Notes on Pineal Gland
PINEAL GLAND:
Attached to roof of the 3rd ventricle.
Melatonin production:
Melatonin secretion is regulated by sunlight and stimulation of the activity of the suprachiasmatic nucleus in the hypothalamus. Melatonin regulates day/night cycle. It also may regulate onset of puberty. Also contains neuroactive peptides. (TRH, LHRH) and somatostatin. Associated with mechanisms that regulate circadian rhythm. Body rhythms and onset of puberty. There is an association between light, the pineal gland and depression.
Clinical Application:
Often the pineal becomes calcified. Useful in radiology to determine shift of the midline by a space-occupying lesion. Mainly replaced today by the use of CT-scans of the brain. Phototherapy, which acts like sunlight to inhibit melatonin secretion, is effective in the treatment of "winter depression."
