[Changes in the neuronal background activity of the central gray substance of the midbrain to motor cortex stimulation in rats].
Motor cortex stimulation induced inhibition of the background activity (BA) in 47% periaqueductal gray neurons, excitation--in 20% and had no influence in 32% neurons. Most of the activated neurons (67%) had the 3d type of BA. Neurons with the 1st type of activity did not respond to the cortex stimulation.
