[Responses of neurons of the embryonal neocortex transplanted into the vibrissa projection area of the somatosensory cortex of the adult rat].
Pieces of embryonic rat neocortex were grafted into the barrel-field of adult rats. Extracellular activity of the grafted neurons was registered 3-4 months later. The background neuronal activity in the grafts did not differ neither in pattern, nor in frequency (3.7 +/- 1.4 spikes per s) from that of the normally developing somatosensory cortex. About 57% of the grafted cells responded to deflexion of the contralateral vibrissae by on-effects, 30%-by phasic increase of discharge frequency and 13%-by initial suppression of spontaneous activity.
