title: [Correlation between the ipsi- and contralaterally directed nerve fibers from the C2 zone of the rat cerebral cortex].
abstract: On frontal sections of the brain of albino rats, by means of peroxidase technique, studies have been made on peculiarities of distribution of cortical nervous fibers from somatosensory zone C2 in fugal and comissural directions. Horseradish peroxidase was administered electrophoretically in the focus of the response to electrical stimulation of the distal part of contralateral forelimb of the animal. The data obtained were compared with the results of the distribution of labeled fibers from other, more lateral and medial zones. Single retrogradely labeled cells in symmetrical (with respect to peroxidase application zones) C2 areas of contralateral hemisphere were found indicating the existence of single comissural connections between these parts of the brain cortex. It was established that among anterogradely labeled fibers emerging from the label zone in the focus of the response, comissural ones constitute 34-44%, whereas among fibers from the same zone outside the response focus their share increases up to 52-55%.
