[Proposed inhibitory neurons of the auditory cortex in the cat]

A complex of properties of inhibitory neurons in the auditory cortex is defined according to the peculiarities of IPSPs recorded in many cortical neurons. 12 units with such properties were found in a group consisting of 54 cells. These low-threshold units were localized predominantly in layers III-IV, had no background activity and responded to afferent volleys by short-latent barbiturate-resistant discharges (1-4 spikes).
