retrograde label of central nucleus neurons by dye transport from injections into the pontine parabrachial nucleus and the nucleus of the tractus solitarius combined with cgrp immunohistochemistry established that many neurons in the central nucleus which receive dense pericellular innervation from cgrp-immunoreactive axons are projecting caudally to the parabrachial nucleus or , to a lesser extent , to the nucleus tractus solitarii .
