Building the Brain

Cellular architecture of the mouse embryo brain (neocortex, in particular) at E10.5. Different cell types are shown in different colours: salmon (neuroepithelial cells, NECs), orange (asymmetrically dividing NECs), blue (first neocortical neurons), and red (Cajal-Retzius cells). NECs and some differentiating neurons are anchored to the pial basement membrane (in yellow).
