One article describes the role of the pineal gland in more technical terms here: “The role of the nonvisual photoreception is to synchronise periodic functions of living organisms to the environmental light periods in order to help survival of various species in different biotopes.”
The pineal gland is best known for its role in producing the hormone melatonin from serotonin (triggered by the absence of light) and affects wake/sleep patterns and seasonal/circadian rhythms. Like a tiny pea-sized pine cone it is located near the center of the brain, between the two hemispheres and is a unique brain structure insofar as it is not protected by the blood-brain-barrier. This may also explain why it is uniquely sensitive to calcification via fluoride exposure.
More Than An Endocrine Gland
Technically the mammalian pineal gland is neural tissue, and the cells within the pineal gland – the pinealocytes – have characteristics that resemble the photorecetpor cells in the retina....read more>>>...
