Bilingualism and brain functional asymmetry

The task of the neural organization of the native language, acquired by a direct method and of another language, studied at school, performed correspondingly by the left and the right hemispheres, was studied in the bilingual patient after unilateral electroconvulsive therapy used in psychiatry. It was established that in such a bilingual type the right hemisphere is concerned with the formation of deep semantic structures of the native language while the left hemisphere is responsible for the formation of second language deep structures and of surface structures of both languages. The effect of language learning method on cerebral organization of bilingualism is postulated.     

Neurophysiological codes of words in subcortical structures of the human brain.

Investigations into the cerebral mechanisms of mental activity, using modern mathematical-technical capabilities, allows the transition from study of structural-functional organization to a new stage: the study of neural coding of these cerebral processes.Here we present the results of studying the elementary components of the neurophysiological pattern-code of words and the neurophysiological correlates of the simplest mental processes, generalization, and mental conclusion. The elementary components of the pattern-code are the group sequences of neuronal firing with comparatively stable intervals in between. The processes of mental conclusion and decision making occur when full, compressed, and complex patterns-codes appear in the brain.In discussing the data obtained, the problems of relationship between a part and the whole in activity of cerebral systems is considered, and the hypothesis of a dynamic pace-maker mechanism for cerebral organization of mental activity, is proposed.
