＊題目：The fine structure of the cerebral representation of language: a new perspective from stroke-induced aphasia and fMRI

＊演講摘要：
A dominant neurological tradition views linguistic functions as represented in designated brain loci (a k a “language centers”). That is, it is believed that functional units are supported in anatomical units. The nature of the functional units has changed over the years, shifting from modalities (e.g., speaking, listening, repeating and naming) to linguistic levels (e.g., morphology, syntax, and semantics), to processing components. Anatomical units have by and large remained unchanged – from grossly defined Broca’s area (“the third frontal convolution of the left cerebral hemisphere”), to Wernicke’s area (around the Sylvian Fissure), to the Arcuate Fasciculus and the Angular Gyrus, all in the left cerebral hemisphere. The clinical diagnosis of aphasia has been determined accordingly.

Both functional and anatomical analyses have been based on rather imprecise descriptions. They are, moreover, not entirely in accord with many recent scientific results, that have led to much more precise descriptions of both function and anatomy in the language domain. I will present recent neuroanatomical and neurolinguistic results – from anatomico-behavioral studies with patients with aphasia, and from fMRI studies with healthy adults, that make the picture more precise and nuanced. Specifically, I will present results of experiments that use advanced methods in computational anatomy and in neuroimaging in order to improve anatomical precision, and exploit advances in linguistics in order to improve functional resolution.

This will lead to a redefinition of some of the language regions. This revised view will hopefully have clinical and therapeutic benefit which I will try to sketch.
