[The activity of the parietofrontal neurons in the cat performing voluntary movement].
Unit activity was recorded in area 5 of the alert cat parietal cortex during trained movement of a contralateral forepaw. 224 of 227 cells modified their activity by producing triggering stimulus and/or realizing the movement. The movement-related activity of 67.0% of neurons occurred before the onset of movements. The parieto-frontal and non-parieto-frontal neurons were identified by the presence of antidromic response to the motor cortex stimulation. The movement-related activity changed before the electromyographic response in 79.0% of parieto-frontal neurons and in 63.3% of non-parieto-frontal ones. Parieto-frontal cells were also marked by more distinct responses to the triggering stimuli, light flashes, acoustic tone and tactile stimuli. Possible involvement of the parieto-frontal neurons is considered.
