[Identification and properties of callosal neurons of the sensomotor region of the rabbit cerebral cortex].

Antidromic unit responses to the stimulation of the homotopic area of the contralateral hemisphere were specified in the cortical sensorimotor area of the unanaesthetized rabbit. The response latencies and their variability, the maximal reproduced stimulation frequencies, stability of the response, presence of certain contesting relationships between the background activity and the tested action potentials are as a whole reliable criteria for identifying extracellularly recorded callosal neurons. The criteria of certain relationships between the background and evoked action potentials allowed to disclose callosal neurons with slow conduction.
