ABSTRACT

The concept of neurosecretion is based on special third system that transmits information within the metazoans and accordingly it has been reteriated by several investigatiors. In the pioneering concept of neurosecretion with respect to secretory natures of the neurons occupying the magnocellular regions following adoption of CAHP (Chrome allum haematoxylene phloxene) staining tencnique infact the dual function like secretion as well as conduction and transmission of impulses had to be accepted by the neurologist after a hard trial. The idea of neurosecretory system is developed on the basis of the neurosecretory centers their pathways and neurohaemal organs. The recent light of research attributes the peptidergic neuron elaboration are subjected as bio active peptides distributed in the central nervous system as well as endocrine cells. All the neurotransmitters, neurohormones, classical hormones (Autacoides) can be included in the category of intercellular information transmitters hence the term neurosecretion has a fresh connotation to find its place permanently in the history of neurological studies. In this part of investigation, the attempt has been made to elucided the infliction of different thermal regimes to the cerebral neurosecretory cells.
