Basic Features of Cortical Connectivity and Some Consideration on Language

摘要: Any theory of the neural mechanisms language requires an understanding cerebral cortex, for this organ undoubtedly plays a part in production and perception speech. The connectivity cortical network, our opinion, is best described statistical terms, since no suggestion specific “wiring” individual neurons cortex has ever gone beyond speculation. picture that huge network elements one kind, pyramidal cells, connected to each other by special kind synapse, residing on dendritic spines. These synapses are very numerous, weak, excitatory probably plastic. four properties make it quite likely structure which stores memory associative way. Also, such would be ideally suited embodying information form cell assemblies, as suggested Hebb. Bearing mind now widely accepted, intruiguing imagine what happens there during comprehension language. One clue provided much-studied visual areas where (thanks work Hubel Wiesel) obvious do not correspond anything level morphemes language, but rather signal events at phonemes or even below. generation syllables process involving large sets neurons, chaining into sentences cooperation several parts brain addition cortex.
