In fishes, reptiles, and birds they are hollow, and only two in number (corpora bigemina); they represent the superior colliculi of mammals, and are frequently termed the optic lobes, because of their intimate connection with the optic tracts.
McConnell enlisted in the Army Reserve in July 1967 at the height of the Vietnam War but received a medical discharge after less than six months for an eye condition called optic neuritis, according to limited information that has been made public.
The brain of a fish is very small, compared with the spinal cord into which it is continued, and with the nerves which come off from it: of the segments of which it is composed — the olfactory lobes, the cerebral hemisphere, and the succeeding divisions — no one predominates so much over the rest as to obscure or cover them; and the so-called optic lobes are, frequently, the largest masses of all.
