[Formation of systems of unilateral conditioned reflexes following section of the rostral portion of the corpus callosum].

Unilateral conditioned reflexes and two-link reflex systems with regular rhythmic alternation of positive and inhibitory reflexes were elaborated by Abuladze method in four dogs with a preliminarily dissected rostral part of the callosal body. Whereas the rate of formation of simple unilateral positive reflexes did not differ from that of reflex formation in intact animals, the formation of two-link unilateral systems proved to be disturbed. In spite of considerable stabilization of positive and inhibitory reflexes, ultraparadoxical relations were revealed when the same stimuli were applied in the system which testified to the disturbance of the after-effect dynamics. It has been assumed that rostral parts of the callosal body take part in the fixation of traces as the first component of the memory mechanism.
