Document Summary
Chapter seven: life-span development of the brain and behaviour. Development of the nervous system can be divided into six distinct. Caenorhabditis elegans, a tiny worm with fewer than thousand cells , out of which 302 are neurons: since its body is transparent, it is easy to trace the origin of each neuron. In vertebrates, the paths that cells take to form the complete nervous system is more complex: anatomical and genetic studies show that in vertebrates, the paths of development include more local regulatory mechanisms. In rats, exercise boosts neurogenesis- an effect which can be blocked by stresses such as social isolation. New nerve cells migrate: neurons in the developing nervous system are always on the move, at some stage, the cells that form in the ventricular layer through mitotic division move away to their final location. This is a process known as cell migration.
