CAT scan image (computed axial tomography) of the brain of a 2 years-old infant, illustrating the degree of development of the cerebral hemispheres (the large, heavily-folded \casing\" of the brain) at birth. The pale green areas indicate regions of the brain not yet fully developed (ie the process of connecting the millions of \"circuits\", involving myelination of nerve fibres within the brain, is incomplete - myelinated nerves conduct impulses faster than non-myelinated ones). This is apparent over the frontal lobes (top). Photograph from the Guigoz film \"Naissance du cerveau dix milliards de galaxies\" by Claude Edelmann."
