[Activity of neurons of the motosensory cortex during natural locomotion in the cat].

Abstract

The activity of 42 neurons in the motosensory cortex was recorded during natural linear locomotion in two awake cats. Periodic alternations of the activity in 9 of 12 PT cells and in 13 of 30 non-PT cells were observed with respect to the locomotor cycle (modulation). The depth of the modulation of PT cells and non-PT cells was the same. The maximal-minimal activity ratio in the cycle was 16 for very modulational PT cells and was 4 for less modulational PT cells.
