"Speech and Cerebral Localisation”, by Henry Head, Brain, vol. xlvi. Part iv., 1923 (London: Macmillan and Co., Ltd.) 6s.net.
A description of the tests appeared in Brain, vol. xliii., 1920.
The “classical” localisation of cortical function was completed with Wernicke's localisation of a centre for “auditory images” in 1874. Despite Hughlings Jackson, the subject then entered upon a phase of complete sterility which lasted until Marie's “Revision of the Question of Aphasia” in 1906.
The localisation of cortical injuries in Head's cases was as follows: Verbal defects, the lower portion of the central convolutions and the parts beneath them; syntactical, an area above and below the superior temporal fissure; nominal and semantic, between the post central fissure and the occipital region, the latter the more postero-medial.
