Abstract: The authors investigated electroencephalographic correlates of positive emotional reactions in 28 infants aged from 3 to 10 months. An analysis of the space organization of the hypersynchronous 4 Hz frequency theta-rhythm attending emotional reactions has shown that depending on the type of impact, neural elements in the anterior or posterior cerebral cortex synchronously come into play. It is assumed that the arrangement of the above type of activity is due to both nonspecific activation of the cortex through the influence of the subcortical structures and due to the mechanisms of local activation becoming involved in the realization of the response depending on the biological quality of the irritant and the nature of the activity induced by it.
