[Reverse temporary connections upon stimulation of symmetrical portions of the tongue].
Unilateral conditioned and indifferent acoustic stimuli were presented to dogs during the achievement of the unconditioned reflex to the stimulation of the contralateral side of the tongue. Formation of a backward temporary connection was observed with its typical features of a short manifestation of the effector reaction and of its rapid disappearance. A more stable backward connection was formed to previous positive conditioned stimuli, and a less stable one, to previously indifferent ones. It has been found that the elaboration of the backward connection as of a direct one, is attended with the formation of an excitation focus which contributes to a protracted manifestation of backward connections against the background of a contralateral excitation focus. The backward temporary connection, unlike the direct one, rapidly passes into a latent state in which it persists for a long time.
