Abstract
Responses of single auditory neurons of the cat to sound stimulation were recorded from the medial geniculate body and the cortex with hyperfine microelectrodes filled with 3[image] KCl solution. The narrowest response areas of single neurons were obtained from the medial geniculate among the regions from the periphery up to the cortex while at the cortex they were rather wide as at the periphery. The sigmoid relation between the number of spikes per sec of response and the intensity of sound was observed up to the level of the medial geniculate body and not at the superficial layers of the cortex. It is thus concluded that analysis of compound sounds may be accomplished at the medial geniculate and the function of the auditory cortex may consist in the integration of analyzed sound.
