title: Neuronal activity of the supplementary motor area (SMA) during internally and externally triggered wrist movements.
abstract: The activity of neurones was recorded from the supplementary motor area (SMA) of monkeys while they were performing a discrete, arbitrary wrist movement. The cells responded similarly whether there was a triggering stimulus at the time of the movement or not. This experiment indicates that SMA neurones are active both in relation to externally triggered and internally initiated (voluntary) actions.
