title: Activity of neurons in limbic cortex during stimulation of somatosensory zones.
abstract: The effect of high-frequency and burst stimulation of the first and second somatosensory zones on the activity of identical neurons in the anterior limbic cortex was studied comparatively in acute experiments with cats. A histogramic analysis of neuronal responses in the limbic cortex showed that most background-active cells responded to stimulation of both the first and the second somatosensory zones. Both zones variously adjusted the activity of neurons in the limbic cortex. It was found that the responses in the limbic cortex with the maximum density of the potentials of long-latent reactions are recorded during stimulation of the first somatosensory zone. It was established that the first and second somatosensory zones exert a preferentially activating influence on neurons in the anterior limbic cortex (51.5 and 66.6%, respectively), inhibitory responses comprised 33.3 and 20.0%, while mixed responses were recorded in 15.5 and 13.3% of the neurons, respectively. It was shown that the somatosensory zones exert a modulating influence on the activity of neurons, thus participating in the regulation and processing of information entering the limbic cortex.
