Synchronization of spontaneous activity of skeletal muscle, autonomic nerves, and brain structures in cats.
Acute and chronic experiments with recording of electrical activity of skeletal muscle, autonomic nerves, and some brain formations were performed on cats. Spectral correlation analysis showed that the spatial synchronization of electrical activity for the autonomic nerves and brain formations within the frequency range of 25--35 Hz, revealed by previous investigations, extends also to skeletal muscle. It is postulated that the presence of a widespread rhythm of 25--35 Hz is a factor facilitating the transmission of influences in the nervous system through frequency potentiation of synaptic action.
