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.     

The British Archaeological Association Honorary Secretary’s Report For 1939

Abstract

In the Lady chapel at the east end of the north aisle of the church at Pucklechurch (Gloucestershire) are two effigial monuments, which have received little scholarly attention. The monuments are attributed to William de Cheltenham (d. between 1371 and 1374) and his wife Eleanor, and were set up in his lifetime within the chantry chapel dedicated to St Mary which William received licence to establish at Pucklechurch in 1337. Little remains of the chapel except an exquisite altar frontal. During the 19th century the two effigies were transposed. Various aspects of the conception and design of the Pucklechurch monuments reflect developments in monumental sculpture in Herefordshire.     

La Salle dite de L'Echiquier,au Château de Caen

RECOGNITION IN THE Castle Museum, Nottingham, of a ‘lost’ sword from a Viking-age warrior's grave excavated at Donnybrook, Co. Dublin, in 1879, has prompted a reassessment of the burial, which is discussed in relation to other Viking-age burials in the ‘Irish Sea province’. Detailed metallurgical analysis of the sword, undertaken during conservation, has provided important information about the techniques of its construction, and has demonstrated the potential of a variety of analytical approaches.     

Selective woodland exploitation for charcoal production. A detailed analysis of charcoal kiln remains (ca. 1300–1900 AD) from Zoersel (northern Belgium)

A detailed study of charcoal burning activities has been made for the Zoersel forest (Northern Belgium) based on an inventory of charcoal kiln remains, the analyses of wood charcoal and other charred botanical macroremains and radiocarbon dating of 10 of these kilns. Age determination of the youngest kilns was refined by dendrochronological analysis of trees growing on top of these kiln sites. The results show that, although many kilns were found, charcoal was produced in Zoersel only at certain moments during late and post-medieval times suggesting that charcoal burning was not a part of the regular management practice of these forests. The wood used for the production of charcoal mainly consists of taxa of alluvial (alder) forests while the kilns are situated on sites that currently are rather dry, with an oak dominated vegetation. For the older kilns, this contrast could be explained by an important change in local soil conditions. The younger kilns may be related to the conversion of alder woodland to grassland in the lower parts of the domain, with the kilns being constructed in the nearby dryer woodland areas.
