[Role of dominant motivation in organizing the functions of the higher divisions of the auditory analyzer in the cat].
In chronic experiments on cats, reorganization of initial interrelations between alpha-activity of higher parts of the auditory analyzer during acoustic stimulation was of a selective character and depended on motivational properties of the elicited excitation. A conditioned acoustic signal of alimentary situation, greatly intensified the functional conjugation of the majority of studied auditory projections and a number of non-specific structures, while in a defence situation there was a considerable reduction of correlative dependence between compared characteristics of the auditory centers state and a change in the hierarchy of their functional interrelations.
