The process in evolution where an organism develops a head with concentrated sensory and nervous systems at the front of its body.
Cephalization is an important step in the evolution of many animal species, allowing for better sensory perception and coordination.
Cephalization is formed from "cephalus" (from Greek "kephalē", meaning head) and "-ization" (meaning the process of making or becoming). The term refers to the evolutionary trend in which the nervous system and sensory organs become concentrated in the head region of an organism.
Think of 'head' ('cephalus') and the process of 'becoming' ('-ization') to remember that cephalization means the process of developing a head with concentrated sensory organs.
