Abstract

Pineal destruction and melatonin interference tests reveal the distinct roles of the pineal gland and suprachiasmatic nucleus (SCN) in regulating skin and core temperature rhythms in rats.

  • The pineal gland appears to up-regulate skin temperature, while the SCN down-regulates it.
  • The pineal may serve as the primary regulator for the skin temperature rhythm.
  • The SCN is primarily responsible for controlling the core temperature rhythm.
  • Both nuclei communicate through neuroendocrine signals to maintain circadian temperature balance.
