The Pineal Overall aim : To achieve an integrative understanding of the relationship between the biological clock (the suprachiasmatic nucleus) and the pineal gland and how the pineal hormone, melatonin, regulates daily (circadian) and seasonal (circannual) biological rhythms. Specific Study Objectives To define : the suprachiasmatic nucleus (SCN), the superior cervical ganglion (SCG), the pineal gland, melatonin, free running, time cues, periodicity, seasonal affective disorder To describe - the evolution of the pineal gland - the biosynthesis of melatonin, - how daylength is converted into a biochemical signal

Unformatted text preview: -how the activity of the biological clock (the SCN) drives circadian rhythms-how melatonin regulates the activity of the SCN To draw the retinal-pineal pathway (note the PVN here) To explain-how destruction/disease (e.g. blindness) could interfere with the SCN, melatonin and activity rhythms-how the intrinsic clock rhythm (periodicity) of the SCN affects activity rhythms (the human is at 25h; a known mutant hamster is at 23h)-what happens to melatonin in constant darkness/constant light-effect of light on melatonin-jet lag-role of melatonin in reproduction...
