title: [Modulation of pyramidal responses of the sensomotor cortex after combined stimulation of the lateral hypothalamus and the sensomotor cortex of the rat].
abstract: Periodical pyramidal tract (PT) stimulation in freely moving rats has been shown to be accompanied by statistically significant increased functional activity of neuronal populations of the sensorimotor cortex (SMC) manifesting as potentiation of the primary positive phase of the pyramidal-cortical response (PCR). When periodical PT stimulation is combined with the lateral hypothalamus (LH) stimulation of the same periodicity, a statistically significant increase in the magnitude of potentiation of the PCR positive phase compared to that occurring without the LH activation is observed. When the periodical PT stimulation is combined with the LH and SMC stimulation of the same periodicity, the potentiation of the PSR positive phase increases significantly in comparison with the potentiation occurring without the SMC stimulation.
