Cephalization is considered an evolutionary trend, whereby nervous tissue, over many generations, becomes concentrated toward one end of an organism. This process eventually produces a head region with sensory organs. Cephalization is intrinsically connected with a change in symmetry. It accompanied the move to bilateral symmetry made in flatworms...

In biology, cephalization is a term proposed to denote a tendency in the development of animals towards a localization of important parts in the neighbourhood of the head, as by the transfer of locomotive members or limbs to the head (in the Cephalopoda, for example). The term is also used to indicate the degree in which the brain dominates over th...
