[Conditioned reflex leg placing reaction induced by stimulation of brain structures].
The mechanogram of fore-leg movement and evoked potentials in the leg cortical motor area this as well as biceps EMG were recorded in 4 cats in chronic experiment during conditioned placing reactions, elicited by tactile stimulation of the paw tip and by electrical stimulation of several cortical and subcortical brain structures. Mean latency of the conditioned movement and its dispersion were of the same order of values during reactions caused both by tactile stimulation and by electrical stimulation of the cortical motor area. During placing reactions to the stimulation of the sensory cortex, ventral posterolateral nucleus of the thalamus and the cerebral peduncles these values were significantly higher than in the first case.
