[Synchronization of the background activity of skeletal musculature, autonomic nerves and cerebral structures in cats].
The background electrical activity of skeletal muscles, autonomic nerves and several brain structures was recorded in cats under acute and chronic conditions. The spectrum-correlation analysis showed that the spatial synchronization within the range of 25 to 35 Hz between autonomic nerves and brain formations (established in previous experiments) comprises the skeletal muscles as well. One of the possible mechanisms by which the rhythm of 25 to 35 Hz facilitates activity in the nervous system is suggested to be related to the frequency potentiation of the synaptic transmission.

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.
