The process by which new neurons are formed in the brain. Neurogenesis is crucial when an embryo is developing, but also continues in certain brain regions after birth and throughout our lifespan

White coloured nerve tissue in the brain is made up of myelin covered axons, which transmit electrical signals through the nervous system. The white matter lies underneath the grey matter of the cerebral cortex and white matter tracts travel down through the brainstem and into the spinal cord.
