Fig. 8From: Expression of vasopressin and its receptors in migraine-related regions in CNS and the trigeminal system: influence of sexAVP in the red nucleus (R), lateral parabrachial nucleus (LPB) and locus coeruleus (LC). a Large neurons in R showed intense AVP immunoreactivity and in addition, some positive fibers were found in this region. b LPB showed AVP expression in the fibers in a pearl-like pattern (arrows) and c in the LC large bipolar neurons displayed granular staining in the cytoplasmBack to article page
