Théodore Flournoy on synesthetic personification

In 1893, Théodore Flournoy published a landmark book on synesthesia — Des phénomènes de synopsie [Of Synoptic Phenomena]. The book presented a pioneering chapter on synesthetic personification, including numerous striking case examples, and it is frequently cited by twenty-first-century researchers as providing some of the earliest examples of the phenomenon. Flournoy employed a broad definition of personification — the representation of stimuli as concrete and specific individuals or inanimate objects. This definition encompassed a more extensive set of phenomena than the definition used by researchers today and was illustrated by cases that would fall outside of contemporary subtypes of synesthetic personification. Yet, Flournoy’s seminal work remains unavailable in English, and the extent of the phenomenon that he described has not been discussed in the contemporary literature. We provide an unabridged translation of Flournoy’s chapter “Des personnifications” [“Of Personifications”].     

Pioneers of Affective Neuroscience and Early Concepts of the Emotional Brain

Views on the representation of emotion in the brain, as formulated about a century ago, are described, with a focus on the Vienna physiologist and psychologist Sigmund Exner, the psychoanalyst Sigmund Freud, and the French physician Israel Waynbaum. All three can be characterized as forerunners in the field of “affective neuroscience”. By the turn of the century, they had developed a neural network theory of emotion which included a stage of pre-cortical processing. In spite of their otherwise very diverse theoretical backgrounds, their concepts of parallel processing routes were highly similar. It is interesting to note that their ideas were on line with present-day views on the neural substrates and physiological characteristics of emotional processing, although none of the three scientists could rely on the refined anatomical knowledge available nowadays.     

The Development of a Scientific Understanding of Synesthesia from Early Case Studies (1849–1873)

The first case of synesthesia was reported in 1812 (Jewanski, Day, & Ward, 2009 Jewanski, J, Day, SA and Ward, J. 2009. A colorful albino: The first documented case of synesthesia, by Georg Tobias Ludwig Sachs in 1812. Journal of the History of the Neurosciences, 18: 293–303. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). However, it took almost seven decades before the idea of synesthesia entered the mainstream of science and, subsequently, art. There are no known new cases described between 1812 and 1848, but in the following three decades there are at least 11 reported cases of synesthesia and many reviews of these cases. This comes at an important period in the history of the neurosciences, and for sensory physiology in particular. However, the literature that describes synesthesia during this period is largely unknown to contemporary researchers and historians. The aim of this review is to discuss the reports of synesthesia during this period, providing translations of some key passages, and to place these reports within the contextual framework of nineteenth-century neuroscience.     

William Alexander Hammond: The Centenary of His Death

In the United States, the field of clinical neurology began within the medical practice of a single physician, William Alexander Hammond. In the 1870s, this New York medical practitioner became the first American physician who limited his practice to patients who suffered from symptoms potentially due to dysfunction of the nervous system. From the experience of his huge practice, Hammond wrote the first American textbook of neurology. With Silas Weir Mitchell, he founded the American Neurological Association. The year 2000 marked the 100th anniversary of Hammond's death and stimulates this brief survey of his life.
