title: [Total electrical response to sound in the acoustico-lateral region of the carp, Cyrpinus carpio, medulla oblongata].
abstract: In order to investigate foci of the electrical activity, studies have been made on the topography and form of total reactions to sound in the acoustico-lateral part of the medulla oblongata in the carp C. carpio. Two foci of the activity were found -- medical and ventral ones. Responses in the medial and ventral foci differ with respect to the form, latency (2.0--2.5 and 1.3--1.5 msec. respectively) and amplitude (200--600 and 50--200 microvolts respectively). It is suggested that total reactions in the medial focus reflect the activity of the nervous elements of the medulla oblongata, whereas the responses of the ventral focus reflect mainly microphonic reactions of sacculus of the inner ear of the carp.
