[Tonic inhibitory effect of the cat brain on spinal interneurons]
Abstract:
Cord dorsum potentials were recorded in the acute experiments on cats. The relationship between the N-component of the cord dorsum potentials and the strength of stimulation of the big femoral nerve was studied. After the transsection of the half of midbrain tegmentum the increased curve slope indicating the rise in cord interneuron excitability was mainly observed on the contralateral side. The same results were observed after the removal of the contralateral somatosensory cortex or contralateral section of midbrain basis. The data indicate the tonic inhibitory influence of cortical structures on cord interneurons, which participate in the transmission of somatosensory signals.
