A sample unit for initiation of stand and the areal distribution of 294 similar units. A. Peri-event time histogram of an example unit for the initiation of stand-up demonstrated high and tonic activity after target onset (Purple inverted triangle) but inhibited during the actual push and Center Release (Pink triangle), bin size = 30 ms. B and C. coronal and vertical view of the distribution areas of similar units in two monkeys. D and E, coronal and vertical view of the distribution areas of similar units in monkey H. F and G, coronal and vertical view of the distribution areas of similar units in monkey V. These areas are close to the midline (0 mm), just anterior to the central sulcus (dotted white line shown). CS: Central sulcus, PA: posterior–anterior, DL: dorsal-lateral.
