Hypothalamo-newosecretory complex of Megalaspis cordyla comprises nucleus preopticus (NPO), nucleus lateralis tuberis (NLT) and their axonal tracts. NPO is a paired structure situated on either side of the third ventricle anterodorsal to the optic chiasma and looks inverted Lshape in the sagittal section. NPO is divisible into a dorsal pan, magnocellularis (PMC) consisting of large neurons and ventral pars parvocellularis (PPC) formed of smaller ncurosecretory cells. NLT cells are distributed uniformly in the infundibular floor adjacent to the pituitary stalk. Neurons of PMC and PPC contribute beaded axon8 to form neurohypophysial tract Other neuroendocrine centres like nucleus preopticus basalis lateralis (NPBL) and nucleus preopticus periventricularis (NPP) have also been described. in this species.
