A fascinating topic this week, the pineal gland. The neuroendocrine structure that releases melatonin and helps regulate sleep cycles. Also, a structure that throughout history people have tried to assign all sorts of unusual functions. Join us this week as we try to unravel fact from fiction whilst covering location, function, and a smidge of clinical relevance.

Terms covered this week are the pineal gland, melatonin, pineal or parietal eye. Circadian rhythm, diurnal & sleep hygiene.
