Fig. 3. CARTp-immunoreactive perikarya in the diencephalon and
the mesencephalon. A: Immunoreactivity in the rostral diencephalon.
Note stained cells in the nucleus of Bellonci (B; arrows). B: Immunoreactive
cells and fibers in the infundibulum (inf) and the dorsal
hypothalamic nucleus (dHy). C: Stained cells of the magnocellular
preoptic nucleus (Mg) in the wall of the infundibulum (inf). Note that
their long dendrites are oriented laterally, toward the surface of the
brain. D: Immunoreactive cells in the hypothalamus and the Edinger-
Westphal (EW) nucleus and intensely stained axon terminals in the
neural lobe of the pituitary gland (pn). Sagittal section. Rostral is to
the left. E: Immunostained infundibular neurons with long dendrites
at the level of plane E in Figure 1. Note stained perikarya in the
ventromedial (VM) and the posterior entopeduncular nuclei (epp).
F: Immunostained fibers in the pars nervosa (pn) of the pituitary
gland and median eminence of the hypothalamus. The intermediate
pituitary lobe (pi) is immunonegative, whereas some cells in the distal
lobe (pd) reveal weak immunoreactivity. G: Detail of the median
eminence, with small and less numerous stained dots in the internal
zone (iz) and large stained dots and short varicose fibers in the
external zone (ez). Hd, dorsal habenula; Hv, ventral habenula. 3rd,
third ventricle. Scale bar 200 m in A,B; 100 m in C,E; 300 m in
D; 150 m in F; 15 m in G. |
