Pineal Gland, what is it and what is its function? episode 011

Pineal Gland geometrically is in the center of the brain. It is the size of a pea. It has more blood flow than any other part of the body except the kidney. The cells in the Pineal gland are the same as the retina in the eyes. The ancient Indian call this for the third eye. If you have watched any Indian movie or some Indian ceremony like marriage party, you have surely seen a red-colored dot Indian people place on the forehead right above the nose between two eyes on the forehead.
