in conclusion , in the forebrain and diencephalon ( 1 ) cgrp-like immunoreactivity appears in fibers earlier than in cell bodies , suggesting that at least some of immunoreactive fibers originate from the lower brainstem , and ( 2 ) high density of cgrp-ir structures present in the brain at embryonic and early postnatal stages may indicate that cgrp could be an important factor involved in the developmental organization of the central nervous system .
