Abstract
We have studied in acute experiments the neurons of the associative parietal cortex in the cat, using the microelectrode take-off technique. We identified the efferent neurons sending axons to the sensomotor cortex, the red nucleus, and the pontine nuclei by antidromic stimulation. We investigated the collateral branching of axons of neurons projected simultaneously into two of the formations mentioned, using the impulse collision technique. We studied the characteristics of the spatial distribution of efferent neurons in the parietal cortex.
