Table 3. Density of Tbr2+ cells per 2500 mm² in dense inner band and diffuse outer band.

Macaque age	Total Tbr2+ cells counted	Density of dense inner band	Density of diffuse outer band
E50	286	32	NA
E65	784	25	12
E80	322	21	15
E100	157	13	5

Density measurements are average number of Tbr2+ cells in the dense inner band and diffuse outer band counted in at least three 2500 µm² regions of interest at each age in each species. Bands were identified by the pattern of Tbr2 immunoreactivity.
