[Correlation between the brain serotonin and the hypothalamic neuro-secretion in rat (author's transl)].

Parenteral administration of PCPA (200 mg/kg) induces changes in the quantitiy and the distribution of hypothalamic neurosecretion. This action appears very quickly and increases during the 48 hours following the injection. The histologic observations disclose a large accumulation of neurosecretory material in the supraoptic nuclei and in the accessory magnocellular groups of the anterior hypothalamus.
