A brain (or encephalon) is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. (wikipedia.org)
While invertebrate brains arise from paired segmental ganglia (each of which is only responsible for the respective body segment) of the ventral nerve cord, vertebrate brains develop axially from the midline dorsal nerve cord as a vesicular enlargement at the rostral end of the neural tube, with centralized control over all body segments.
