Neuroepithelium, the developing brain

Artist’s impression of neuronal organisation in the brain based on experiences and research in neuroanatomy. The light blue ovals are the nuclei of cells in darker blue. The green within the cells represents actomyosin (a protein complex composed of actin and myosin). The pink dots are centrosomes (important in the organisation of microtubles). The large red area is the embryonic ventricle (areas of the brain that contain cerebrospinal fluid). The image attempts to capture the dynamics of the proliferating brain.
