Distribution of Pax6+ cells during neocortical development.

<p>Numbers represent the average percentage of Pax6+ cells in each compartment of the developing somatosensory cortex per radial unit, averaged across <i>n</i> 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.
