Phrenology (study bumps on skull) focused attention to the localization of function- the idea that various brain regions have particular functions. Biological perspective studying links between biological activity and psychological events. Announcing discoveries about the interplay of our biology and behaviour and mind. They share a focus on the links between biology and behaviour. Phrenology faded because it had no scientific basis-skull bumps don"t reveal mental traits and abilities. Neural information system is complexity built from simplicity. Building blocks are neurons, or nerve cells. Each consists of a cell body and its branching fibers that receive messages and conduct impulses toward to cell body (dendrites) The cells lengthy axon fiber passes the message through its terminal branches to other neurons or to muscles or glands. Axons are encased in a myelin sheath a layer of fatty tissue that insulates them and speeds their impulses.
