Changes in cellular composition of the neocortex. A) Changes in the total number of cells (left), number of neurons (center), and number of non-neurons (right) in the neocortex at different developmental stages. While the total number of cells and non-neurons increases across the ages we sampled, the number of neurons does not change. B) Changes in total cell density (left), neuronal density (center), and non-neuronal density (right) across development. The density of both cell types was highest at P18, decreased by P35 and then remained unchanged through adulthood. C) The percentage of all cells within the neocortex that were neurons decreased across development. Mean + s.e. Values with different letters are significantly different.
