Assemblage Biography and the Life Course: An Archaeologically Materialized Temporality of Richard and Sarah Hopkins

A substantial assemblage of material culture deposited ca. 1843–45 in Cambridge, England, is examined from a biographical perspective in terms of what it tells us of the preceding century or so—ca. 1730-1845—rather than the contemporary 1840s. It reveals a materialized temporality, bound up principally with the lives of the college cooks Richard and Sarah Hopkins but also numerous other individuals. The assemblage is also viewed from the perspective of the processes of discard and deposition, and the likely relationship of those involved in this to Richard and Sarah Hopkins.     

Ivory Coast Prehistory: recent developments

Ten years after Raymond Mauny's overview of Ivory Coast archaeology, Robert Chenorkian summarizes and illustrates recent developments in Ivoirian prehistory: palaeolithic industries discovered in stratigraphy, epipalaeolithic artefacts with¹⁴C dating, neolithic industries, and new data on shell middens. A table of radiocarbon dates resulting from the last ten years of research is included.     

Optical dating and sedimentary record from the terrace depositional profile of the Warta River (Central Poland)

Results of OSL dating and sedimentary studies from the profile of the low alluvial terrace of the middle Warta River are presented. The samples were dated using the single-aliquot regenera-tive method. Dating was used to establish a timing of the Weichselian Late Glacial events in the river valley environment. Stable conditions on the floodplain are expressed by the deposition of organic-rich series radiocarbon dated at 12 900-12 600 cal BP and 11 600-10 770 cal BP. Samples for OSL dating were collected from the mineral material deposited during the intensification of flood events during the Weichselian decline. The results obtained for the alluvia range from 12.78 ± 0.62 ka b2k to 14.33 ± 0.74 ka b2k. Sedimentological criteria allowed to distinguish between particular flood events. Overestimation of OSL ages is probably a result of rapidity of environmental changes in that time.     

Rice,Ethnicity, and the Collation of Archaeobotanical Data for Prehistoric Korea

Nationalism and archaeology are universally and almost unavoidably intertwined. The multilevel influence of nationalism not only delimits the legitimate interpretations of archaeological data but also determines the retrieval, analysis and dissemination of data. This point is illustrated in the present study with a historical overview of archaeobotanical data collation at four prehistoric sites, two in North Korea and two in South Korea, that were excavated between 1957 and 1981. The paper examines the persistent and increasing archaeological interest since the early 1970s in the search for rice, a crop that constitutes an integral part of the Korean ethnic identity. The remains of rice have tended to receive more scholarly attention, be subject to extended discussion, and be more widely publicized, compared to the relatively neglected research on the remains of other “miscellaneous” crops. This demonstrates that botanical remains from archaeological sites, often presented as an outcome of scientific scrutiny, are a social product and that greater attention needs to be paid to local archaeological concerns before the data are compared internationally or across different research traditions.     

Deglaciation and Human Colonization of Northern Europe

Few places worldwide experienced Late Glacial ecological shifts as drastic as those seen in the areas covered by, or adjacent to, the massive ice sheets that blanketed much of the northern hemisphere. Among the most heavily glaciated regions, northern Europe underwent substantial ecological shifts during and after the Last Glacial Maximum. The climatically unstable Pleistocene–Holocene transition repeatedly transformed far-northern Europe, placing it among the last regions to be colonized by Paleolithic societies. As such, it shares paleoenvironmental and archaeological analogues with other once glaciated areas where human populations, entrenched in periglacial environments prior to glacier retreat, spread into newly deglaciated territories. Perhaps most significant for northern Europeans were post-glacial effects of the Younger Dryas and Preboreal periods, as shifts in climate, plant, and animal communities elicited several adaptive responses including innovation, exploration, and the eventual settlement of once glaciated landscapes. This paper is a detailed review of existing archaeological and paleoecological evidence pertaining to the Late Upper Paleolithic of northern Europe, and offers theoretical observations on human colonization models and ecological responses to large-scale stadial and interstadial events.     

An Alternative Way Towards Food Production: The Perspective from the Libyan Sahara

Food production originated in various ways in different parts of the world. Plant domestication with the adoption of agriculture has been successful in some areas, but not in others, where animal domestication with nomadic pastoralism proved to be more effective. Likewise, the preceding phases of pre-adaptation and development of a broad spectrum of wild resource exploitation followed different pathways, according to the locally available resources, climatic and geographic conditions, and social organizations. Northern Africa greatly contributed to the understanding of the origin of food production under preconditions that differed from those in the Fertile Crescent. Apart from a narrow strip along the Nile valley, northern African lands are arid and scarcely productive for agriculture. Nevertheless, early studies interpreted northern African archaeological records of the Early and Middle Holocene according to the traditional north-western Mediterranean and Near Eastern frames of reference. Consequently, terms such as Epipalaeolithic, Mesolithic, and Neolithic were uncritically applied to northern African contexts. This paper compares and discusses the evidence for food production in the Near East and northern Africa, considering the question of introduction or local breeds of domesticated animals in the Maghreb and the Sahara. It then reviews the relevant data for long-held diffusionist models of pastoralism into Africa to provide a different perspective and the proper means of interpretation of the northern African archaeological records. Finally, it examines some recent findings from the Tadrart Acacus, in the Libyan Sahara, which contribute to clarification of distinctive African pathways and propose an alternative model for the beginnings of food production.     

Agricultural production in the Central Asian mountains: Tuzusai,Kazakhstan (410–150 b.c.)

Abstract

The site of Tuzusai is located in the Tien Shan Mountains of eastern Kazakhstan; occupation at the site between 410 B.C. and a.d. 150 represents the transition between the Saka and Wusun periods (Saka: 800–200 b.c.; Wusun: 200 b.c.–a.d. 400). Iron Age people of Central Asia are often described simply as mobile pastoralists, yet at Tuzusai, we have evidence that agriculture was practiced along with pastoral transhumance. This multiresource economic system combined pastoralism and hunting with the cultivation of a variety of crops. Our new finding is significant because Tuzusai has the first clear evidence for the presence of agriculture from the Iron Age of northern Central Asia. The diversity of crops grown at Tuzusai required varying labor and time inputs and a well-planned scheduling system.     

The earliest evidence of domesticated wheat in the Crimea at Chalcolithic Ardych-Burun

Abstract

This paper reports the discovery of the earliest evidence of domesticated wheat in the Crimean peninsula from the Ardych-Burun shell midden site, Ukraine. The Ardych-Burun site dates to middle of the 4th millennium cal b.c. For the first time, the chronology of a Ukrainian Chalcolithic period site has been established through direct radiocarbon dating of cereal grains retrieved from it. This discovery allows for a wider discussion of the chronology and geographical origins of domesticated plant species in Ukraine and the role the Caucasian corridor may have played in the spread of agriculture into eastern Europe. The presence of cereal crops in the southern Crimea enriches our understanding of the subsistence strategies of the coastal population, which was previously linked only with pastoralism, hunting, and the exploitation of marine resources.     

Landscapes of Prehistoric Northwestern Sichuan: From Early Agriculture to Pastoralist Lifestyles

We describe a preliminary survey of a relatively unknown part of the eastern Himalayas: northwestern Sichuan. This survey revealed that three phases of occupation are represented across the landscape. Large settlements with dense remains characterize the landscape during the Neolithic (3400–2000 cal b.c.). Following a hiatus in occupation, stone-cist graves characterize the region during the Bronze Age (1450–800 cal b.c.). The lack of settlement remains from this period indicates that mobile pastoralism increased in importance. Finally, between a.d. 500 and 1500, dense scatters of ceramics over a wide altitudinal range correspond to a fragmentation in Tibetan history, when local warlords established themselves in the region. While some changes in occupation and subsistence practices are linked to climate change, others relate to changes in political power. We argue that further survey work is needed to expand our understanding of past land use and the development of pastoralist practices.     

Vernacular names for African millets and other minor cereals and their significance for agricultural history

Apart from the well-known cereals such as sorghum and millet, Africa has a number of small millets, notably fonio, iburu, ?ef and Paspalum scrobiculatum which are poorly represented in the archaeobotanical record. The fragmented distribution of fonio suggests that it was formerly more widely cultivated. The paper uses the patterns discerned in vernacular names to explore their history. Fonio is the most widely distributed and its vernacular names fall into two significant subgroups, in the Mande/Atlantic area of West Africa and in Central Nigeria. Iburu names are only recorded for Nigeria, although there is another region of cultivation in the Atakora mountains in Benin. Names for ?ef are extremely similar throughout the Ethiopian region, suggesting that the crop has been dispersed by a dominant culture, probably the Ethiosemitic speakers, perhaps as part of the diffusion of seed/plough agriculture. The paper calls for further more detailed research on these important and neglected species.     

Deconstructing twinned towers: Lisbon's Expo '98 and the occluded geographies of discovery

This paper develops a critique of Western representations of discovery, centrality and self-identity via a focus on Portugal's Expo '98. Two of the towers of the title were incorporated into the site of Expo '98 (the last universal exposition of the twentieth century), which offered the chance to reiterate the importance of Portugal's imperial discoveries on a global stage and to reaffirm Portuguese national identity in the process. The paper examines how historical and geographical narratives of imperialism and the ‘Portuguese voyages of discovery’ were reworked in Expo '98 to resurrect a national sense of pride in belonging to and pioneering Europe. Critical postcolonial perspectives which break with Eurocentrism are required if the role of other cultures and histories in the Portuguese contribution to the making of modernity is to be appreciated. Such perspectives enable wider reflections about the constitution of the West and the non-West in the making of a multifaceted modernity of which expositions (and monumental towers) are concentrated expressions.

Portugal's was the pioneer empire in more ways than one, and it exhibited all the defects as well as all the glories of the age it inaugurated. No Nation of the fifteenth or sixteenth century ever saw more, reported a greater variety of things, or left more of its imprint on the modern world, whose chief characteristic, after all, is mobility.

Knowing scale: intelle©tual property rights,knowledge spaces and the production of the global

In this article, I am concerned with the importance of knowledge spaces to the construction and politics of scale. I draw together literatures on re-scaling with feminist critiques of knowledge to show how struggles over the scale at which knowledge claims are represented and legitimized are an important, and under-recognized, element of rescaling. I draw from Neil Smith's (1984) concept of scale-jumping to see the construction of the global space of knowledge as a scale-jump in which one particular situated knowledge, Western folk belief, is redefined as global and universal. What distinguishes it from other forms of local/anecdotal/unrecognizable knowledges is its relation to power and its capacity to achieve a scale-jump in which it is defined as global knowledge. I contrast the social, economic and power relations associated with knowledge in the village of Puno in the Philippines with those of technoscientific knowledge, as manifested by regimes of intellectual property, to show that knowledges are not a natural way of understanding a separate, pre-existing world but inform how that world is experienced. I build upon David Turnbull's (1997) concept of knowledge spaces to reveal all knowledges as not only arising from a particular context but also as creating that context.

Connaître l'échelle: les droits relatifs à la propriété intellectuelle, les espaces de savoir et la production du mondial

Dans cet article, je me penche sur l'importance des espaces de savoir dans la construction et les politiques d'échelle. Je marrie les corpus sur les transformations d'échelle et les critiques féministes du savoir pour montrer comment les débats qui entourent l'échelle à partir de laquelle les prétentions au savoir sont représentées et admises comme légitimes sont une dimension importante et peu connue des transformations d'échelle. Le concept de saut d'échelle proposé par Neil Smith (1984 Smith, N. 1984. Uneven Development, Oxford: Basil Blackwell.  [Google Scholar]) me sert de point d'appui pour mieux situer la construction d'un espace mondial du savoir en tant que saut d'échelle par lequel un savoir contextualisé, en l'occurrence les croyances folkloriques occidentales, est redéfini en fonction du mondial et de l'universel. Ce savoir se démarque des autres formes de connaissances locales/anecdotiques/indiscernables par son rapport au pouvoir et par sa capacité d'opérer un saut d'échelle vers un savoir mondial. Je compare les relations sociales, économiques et de pouvoir liées au savoir dans le village de Puno aux Philippines avec celles qui relèvent du savoir technoscientifique, telle qu'elles se manifestent dans des régimes de propriété intellectuelle, pour montrer que ces connaissances ne sont pas un moyen naturel de comprendre un monde distinct et préexistant, mais représentent plutôt une source d'informations sur la manière dont le monde est connu. Je prolonge le concept des espaces de savoir de David Turnbull (1997 Turnbull, D. 1997. Reframing science and other local knowledge traditions. Futures, 29: 551–563. [Crossref], [Web of Science ®] , [Google Scholar]) afin de démontrer que toutes les connaissances proviennent non seulement d'un contexte en particulier, mais qu'elles peuvent également créer ce contexte.

Sabiendo escala: derechos de propiedad intelectual, espacios de conocimiento y la producción de lo mundial

En este artículo trato la importancia de espacios de conocimiento con relación a la construcción y la política de escala. He unido literatura sobre el reescalar con críticas feministas sobre conocimiento para ilustrar como la lucha sobre la escala a que se representa y legitima los conocimientos es un elemento del reescalar importante y poco reconocido. Hago uso del concepto de Neil Smith (1984 Smith, N. 1984. Uneven Development, Oxford: Basil Blackwell.  [Google Scholar]) de saltar escalas para ver la construcción del espacio mundial de conocimiento como un salto de escala en que un conocimiento particular, la creencia folklórica occidental, se redefine como mundial y universal. Lo que le diferencia de otras formas de conocimiento locales/anecdóticas/irreconocibles es su relación al poder y su capacidad de saltar de una escala para otra, así redefiniéndose como conocimiento mundial. Comparo las relaciones sociales y económicas y relaciones de poder asociadas con conocimiento en el pueblo de Puno en las Filipinas con las relaciones de conocimiento tecnocientíficas, tal como son manifestados por regimenes de propiedad intelectual para ilustrar que los conocimientos no representan una manera natural de entender un mundo separado que ya existía, sino que informan la manera en que se experimenta ese mundo. Amplio el concepto de espacios de conocimiento de David Turnbull (1997 Turnbull, D. 1997. Reframing science and other local knowledge traditions. Futures, 29: 551–563. [Crossref], [Web of Science ®] , [Google Scholar]) para revelar que todos los conocimientos no sólo surgen de un contexto paricular, sino que también crean ese contexto.     

Isotopic Reconstruction of the Late Longshan Period (ca. 4200–3900 BP) Dietary Complexity before the Onset of State‐Level Societies at the Wadian Site in the Ying River Valley,Central Plains,China

During the late Longshan period (ca. 4200–3900 BP) settlements on the Central Plains of China underwent a diversification in food production technologies, which set the stage for rapid economic and social development. The introduction of novel domesticates such as rice, wheat, cattle, and sheep not only provided more food choices, but also changed ideas concerning land use, farming techniques, and the use and mobilization of large scale labor forces. To better understand the contribution that these new dietary items and practices made to shaping the late Longshan period societies, a stable isotope ratio study of humans (n = 12) and animals (n = 42) was conducted at the late Longshan period site of Wadian. The human δ¹³C and δ¹⁵N values are clustered into two distinct groups. One group of nine individuals (δ¹³C = −9.9 ± 0.7‰; δ¹⁵N = 7.5 ± 0.5‰) had a predominately C₄ diet based on millet grains with little protein input from the domestic animals. The other group of three individuals (δ¹³C = −14.3 ± 0.8‰; δ¹⁵N = 10.2 ± 0.3‰) had a mixed C₃/C₄ diet of millets and rice and were consuming sheep and cattle. The animals also displayed dietary diversity with the pigs (δ¹³C = −11.3 ± 2.5‰; δ¹⁵N = 6.9 ± 1.0‰, n = 10) and dogs (δ¹³C = −10.1 ± 1.0‰; δ¹⁵N = 7.2 ± 1.1‰, n = 7) having mostly a C₄ plant based diet (millets). In contrast, the cattle (δ¹³C = −12.8 ± 2.1‰; δ¹⁵N = 7.6 ± 0.7‰, n = 9), sheep (δ¹³C = −16.7 ± 0.9‰; δ¹⁵N = 7.6 ± 0.1‰, n = 2), and cervids (δ¹³C = −20.8 ± 0.9‰; δ¹⁵N = 5.0 ± 1.2‰, n = 10) had diets with a greater contribution from C₃ sources such as rice and wild plants. The discovery that humans and animals had different subsistence patterns indicates dietary complexity at Wadian and that rice agriculture, and cattle and sheep husbandry practices were already an important part of the local economy by the late Longshan period in the southern region of the Central Plains of China.

Generational differences in women's attitudes towards paid employment in a British city: the role of habitus

Most studies of women's work orientations are based on the attitudes and experiences of women with dependent children and conceptualise women's decision-making in terms of moral positions on the combination of paid work and motherhood. Thus, work orientations are understood within a ‘gender model’ (Dex 1988 Dex, S. 1998. Women's attitudes towards work, New York: St. Martin's Press.  [Google Scholar]), which assumes that women's family situation drives their attitudes towards paid work. This article draws on qualitative interview data collected from interviews with women in two age groups living in Oxford, UK, to explore generational differences in women's work orientations and labour market behaviour. Drawing on a Bourdieusian framework, it considers specifically how changing social, economic and moral geographies, incorporating expectations about women's economic and caring roles, have influenced the habitus of older and younger women. The results of the study suggest that whilst caring responsibilities clearly influence women's attitudes and employment patterns, paid work is more important to younger women's sense of themselves and ‘gender models’ of work orientations do not adequately describe their attitudes.     

Airports and air-mindedness: spacing,timing and using the Liverpool Airport, 1929–1939

Some popular texts have associated airports with a lack of identity. It is supposed that people are alienated from these ahistorical and interstitial spaces (Augé 1995 Augé, M. 1995. Non-places: Introduction to an Anthropology of Supermodernity, London: Verso.  [Google Scholar]; Castells 1996 Castells, M. 1996. The Rise of the Network Society, Volume 1: The Information Age: Economy, Society and Culture, Oxford: Blackwell.  [Google Scholar]). Other approaches have tended to ignore their sociality, exploring their role within transport networks rather than what goes on within. Through a discussion of the early beginnings of British airport development and the construction of Liverpool Airport at Speke, I attempt to show how there are other contextual geographies to airports. By using the concept of air-mindedness—a moral geographical concept that promoted the belief in the possibilities of aircraft mobility, this paper discusses how social identities became bound to flight, forming the context to the development of the airport and both local and national belonging. This examination will reveal the embeddedness of airports within the times, spaces and uses from which they are produced and consumed. Archival research provides the material for this discussion.

Les aéroports et le sens des choses de l'air: l'espace, le temps et l'utilisation de l'aéroport de Liverpool, 1929–1939

Un nombre d'écrits populaires ont dressé un parallèle entre les aéroports et un déficit d'identité. Les gens, suppose t'on, se sentent aliénés par ces espaces ahistoriques et interstitiels (Augé 1995 Augé, M. 1995. Non-places: Introduction to an Anthropology of Supermodernity, London: Verso.  [Google Scholar]; Castells 1996 Castells, M. 1996. The Rise of the Network Society, Volume 1: The Information Age: Economy, Society and Culture, Oxford: Blackwell.  [Google Scholar]). Dans d'autres cas, on a fait fi de leur socialité, explorant alors leur rôle au sein de réseaux des transports plutôt que de s'intéresser à ce qui se passe dedans. Une discussion sur les tout débuts de l'expansion des aéroports britanniques et de la construction de l'aéroport de Liverpool à Steke tente de montrer comment les aéroports sont situés dans des contextes géographiques différents. Grâce au concept du sens des choses de l'air—un concept moral en géographie qui renforçait la croyance dans les possibilités de mobilité qu'offre l'avion, cet article traite de la façon dont les identités sociales se rattachent au vol créant ainsi le contexte dans lequel se situe le développement de l'aéroport et de l'appartenance locale et nationale. Dans cette étude, il est question de l'enchâssement des aéroports dans les époques, espaces et usages à partir desquels ils sont produits et consommés. La discussion fait état des résultats d'une recherche en archivistique.

Aeropuertos y air-mindedness: espacio, tiempo y el uso del aeropuerto de Liverpool 1929–1939

Algunos textos populares asocian los aeropuertos con una falta de identidad. Se supone que la gente se siente distanciada de estos espacios ahistóricos e intersticiales (Augé 1995 Augé, M. 1995.

The Rise of the Network Society, Volume 1: The Information Age: Economy, Society and Culture, Oxford: Blackwell.  [Google Scholar]). Los enfoques de otros no tienen en cuenta el aspecto social y exploran el papel del aeropuerto en las redes de transporte en vez de explorar lo que pasa dentro del mismo aeropuerto. Por un estudio de los inicios del desarrollo del Aeropuerto Británico y la construcción del aeropuerto de Liverpool en Speke, pretendo mostrar que, con respecto a los aeropuertos, hay otras geografías contextuales para explorar. Haciendo uso de la idea de ‘air-mindedness’—un concepto geográfico moral que fomentaba confianza en las posibilidades de movilidad aeronáutica—este papel habla de cómo las identidades sociales llegaron a ser vinculadas a la aviación, así formando el contexto para el desarrollo del aeropuerto y un sentido de pertenencia, tanto local como nacional. Este estudio revela hasta qué punto los aeropuertos se han arraigado en los tiempos, espacios y usos de los cuales son producidos y consumidos. Hago uso de investigaciones de archivos para este debate.

Influence of Uncertain Source Parameters on Strong Ground Motion Simulation with the Empirical Green's Function Method

A combined stochastic and Green's function approach was developed to simulate strong ground motions in Southwest Western Australia (SWWA) in a previous study. Although it was demonstrated that adopting the source parameters derived from other regions yielded reasonable simulation of ground motions in SWWA as compared with a few available strong motion records, the effect of source parameter variations on simulated ground motions was not known. This article performs a statistical study of the effects of random fluctuations of the seismic source parameters on simulated strong ground motions. The uncertain source parameters, i.e., stress drop ratio, rupture velocity, and rise time corresponding to the empirical source models are assumed to be the respective mean value of the parameter and normally distributed with an assumed coefficient of variation. The Rosenblueth's point estimate method [Rosenblueth, 1981 Rosenblueth, E. 1981. Two-point estimates in probabilities. Applied Mathematical Modelling, 5: 329–335. [Crossref], [Web of Science ®] , [Google Scholar]] is used to calculate the statistics of the simulate ground motion parameters corresponding to different magnitudes and epicentral distances. The accuracy of the Rosenblueth's point estimate method in estimating the mean and standard deviation of ground motion PGA, PGV, and response spectrum is proven by simulating the ground motions from an ML6.0 and epicentral distance 100 km event with both the Rosenblueth's point estimate method and the Monte Carlo simulation method. A sensitivity analysis is preformed to investigate the effect of random fluctuations of each source parameters on strong ground motion simulation. A coefficient of variation model for ground motion parameters is developed based on the simulated data as a function of the variations of the three source parameters and earthquake magnitude, which can be used in probabilistic predictions of earthquake ground motions with uncertain source parameters.     

The Elmenteitan Obsidian Quarry (GsJj50): New Perspectives on Obsidian Access and Exchange During the Pastoral Neolithic in Southern Kenya

Early pastoralists in southern Kenya exploited obsidian sources to supply large regional exchange networks that persisted from c. 3200 to 1400 years ago. Obsidian exchange networks have been a source for speculation on the social and political nature of early pastoralism in eastern Africa. Herders who produced a discrete set of material culture called “Elmenteitan” mainly relied on a particular obsidian quarry site on the upper slopes of Ol Doinyo Opuru (Mt. Eburru), in the Central Rift Valley. These implications of the Elmenteitan pattern for herder social organization have not been systematically investigated. This paper reports on recent surveys and initial excavations at the Elmenteitan Obsidian Quarry (GsJj50) on Mt. Eburru as the central node of a prehistoric herder exchange network. Research revealed a series of stratified extraction and workshopping loci concentrated across a roughly 200-m² extent. Spatial, faunal, ceramic, and lithic datasets support communal resource access by small groups, rather than centralized control. This research has implications for interpreting the role of centralized quarries and resource nodes in the formation of mobile herder exchange and alliance. Networks were an important risk-reduction strategy in unpredictable environments and helped facilitate the spread of African pastoralism.     

Postlesion Recovery of Motor and Sensory Cortex in the Early Twentieth Century

This article addresses early work on partial recovery that followed small motor cortical lesions. Leyton and Sherrington (1917 Leyton, ASF and Sherrington, CS. 1917. Observations on the excitable cortex of the chimpanzee, orang-utan and gorilla. Q J Exp Physiol, 11: 135–222.  [Google Scholar]) studied the motor cortex in apes, hoping to learn more about the contralateral muscle representations. Then they placed small lesions within the precentral cortex, followed by a loss of the contralateral muscle twitches. The sudden loss remained for about one week, but recovery was observed and continued for weeks, up to a standstill. Sherrington and Graham Brown (1913) Graham Brown, T and Sherrington, CS. 1913. Note on the functions of the cortex cerebri. J Physiol (Lond), 46: xxii [Google Scholar] observed the same results in a serial, chronic experiment on a chimpanzee. The brain was sent to Monakow's Brain-Institute in Zurich for investigating the lesions and the degeneration pattern. Constantin von Monakow (1853–1930) had been a pioneer on recovery after acute lesions, coining the term “diaschisis.” During WWI, Graham Brown and Stewart (1916) Graham Brown, T and Stewart, RM. 1916. On disturbances of the localization and discrimination of sensations in cases of cerebral lesions, and on the possibility of recovery of these functions after a process of training. Brain, 39: 348–454. [Crossref] , [Google Scholar] studied a soldier in a British army hospital who suffered from a cerebral gunshot wound, localized in the sensorimotor cortex. Early and prolonged rehabilitation was successful. In 1950, Glees (1909–1999) and Cole (Oxford) placed a small motor-cortical lesion in macaque monkeys; for a few days, the monkeys had difficulties and were slow for the task. Daily training was resumed and recovery was accelerated by alimentary reward. Finally, Lashley (1890–1958) understood that handicapped patients “achieved their goal with variable means.” This demonstrated the value of active and prolonged rehabilitation, in addition to the (passive) recovery of function.
