Abstract

Contractile activity of the frog bladder induced by electrical stimulation of the IX spinal nerve was shown to have a tubocurarine-resistant component. Two main components of the induced motor response were revealed differing from each other in latency, duration and sensitivity to tubocurarine. One of the components seems to be maintained by the activity of cholinergic fibres of the pelvic nerve and ganglion apparatus of the bladder plexus whereas the other component seems to be due to the results of efferent action of sensory terminals on the smooth muscle cells.

Abstract

The evoked potentials in the anterior suprasylvian and posterior sigmoid gyri to the bulbar vestibular nuclei stimulation were recorded in relaxed anesthetized cats. Neuronal discharges of 70 units in the forelimb cortical zone in the posterior sigmoid gyrus were also recorded. 26 neurons responded to the vestibular nuclei stimulation, 6 of them were identified as cortico-rubral neurons. All of them were activated by the radial-nerve muscle branch stimulation. There was no neurons characterized by the muscle-vestibular convergence from the pyramidal tract neurons. The muscle-vestibular afferent system projection to the cortico-rubral neurons is supposed to play a major role in the tonic muscle coordination of the forelimbs.
