Table 6. Distribution of Pax6+ cells during neocortical development.

Macaque age	Total Pax6+ cells	Radial units	VZ	iSVZ	oSVZ	CP (incl. PP/SP/MZ)
E50	1023	3	89% (910/1023)	6.7% (68/1023)	4% (42/1023)	0.3% (3/1023)
E65	2098	3	33.9% (704/2098)	11% (239/2098)	55% (1154/2098)	0.1% (1/2098)
E80	1915	3	20% (381/1915)	26% (493/1915)	51% (974/1915)	3% (67/1915)
E100	1043	2	24% (247/1043)	6% (61/1043)	67% (701/1043)	3% (34/1043)

Numbers represent the average percentage of Pax6+ cells in each compartment of the developing somatosensory cortex per radial unit, averaged across n radial units. Cells were identified through Pax6 immunoreactivity in a minimum of two 200 µm wide radial unit sections from each age in each species. Numbers in parentheses indicate the total number of Pax6+ cells counted in each compartment.
