The pineal hormone melatonin interacts with the neuroendocrine system via high affinity binding sites. The density of these receptors is increased after 72 h constant light or pinealectomy in both rat pars tuberalis and suprachiasmatic nuclei. The present results show that, in rat PT and SCN, this increase can be inversed by a single melatonin injection (50… CONTINUE READING
