- Melatonin Synthesis in the Pineal Gland: Effect of Light Mediated
To determine whether pituitary or ovarian hormones are required for light to influence the HIOMT activity of the pineal gland, the effects of continuous illumination or darkness were examined in adult males, immature females (21 days old), adult females.
