Abstract

Hypothalamus of Tor putitora consist mainly of nucleus preopticus (NPO), nucleus
laterlais tuberis (NLT) and their axonal tracts. NPO is a paired structure
topographically located on either side of the third ventricle anterodorsal to the optic
chiasma. Based on size of the neurosecretory cells, NPO is morphologically
distinguishable into dorsal pars magnocellularis (PMC) comprising larger neuronal
cells whereas ventrally situated pars parvocellularis (PPG) is formed of smaller cells.
NPO neuronal cells were positive (+) to aldehyde fuchsin (AP) and CAHP but they
were also stainable with acid fuchsin in Mallory's triple stain. A few acid fuchsin
+ve neurosecretory globules were also encountered in NPO. NLT neurosecretory
cells were large, pleomorphic and distributed uniformly at the floor of the brain
close to the infundibulum. They stained readily with acid fuchsin. Herring bodies
(HB) were not observed in the hypothalamo-neurohypophysis of the golden mahseer
