| Summary: | To study the organization and cytoarchitecture of the entire olfactory organ, forebrain and pituitary gland in the Indian major carp Labeo rohita, Kluver and Barrera and Aldehyde fuschsin staining techniques are used. In the olfactory system, important cell groups and nuclei identified are mitral cells, smaller sized granular cells and giant cells of nucleus terminalis. In the forebrain, important nucleus of larger sized neurons forming a cluster is located adjacent to the lateral forebrain bundle which is nucleus entopeduncularis in the telencephalon. Diencephalon is divided into preoptic area, hypothalamus, thalamus and epithalamus. In the preoptic area, both AF-positive and AF-negative neuronal groups are identified. Nucleus preopticus which is divided into preopticus pars paraventricularis and pars magnocellularis are AF-positive. In the preoptic area, nucleus of anterior commissure and nucleus preopticus periventricularis are AF-negative. On the ventrolateral side of the horizontal commissure (HC) in the preoptic area, nucleus of HC is localized. In the hypothalamus, behind the HC, tuberai area starts. In this area, nucleus hypothalamics is found on lateral side of the third ventricle. In the tuberai area near the infundibulum, nucleus lateralis tuberis is identified. In the caudal tuberal area, lateral side of the third ventricle shows nucleus recesses lateralis. Dorsal to the tuberal area, paraventricular organ is identified and nucleus inferior lobi is located on lateral side. Dorsal to the hypothalamus, thalamus shows dorsal and ventral thalamic nuclei. In the epithalamus, paired habenular ganglia are present dorsal to the thalamus. Pituitary is platybasic with short stalk and is forward in position. |
