ABSTRACT

Histophysiological status of the neurosecretory cells to one of the major ganglia has been studied to correlate the impact of temperature fluctuation [low (4°C, 10°C), near ambient (20°C, 25°C) and high (30°C, 35°C)] on their secretory dynamics. Side by side, the histochemical nature of the neurosecretory material has also been recorded. In both the profiles of study individuals exposed to near ambient temperature are being considered as normal. And finally, the histochemical analyses are made under different temperature regimes cited elsewhere on the cerebral neurosecretory elements to ascertain correlative biochemical changes.
