I read that the pineal gland is the only part of the human body that is not "connected" to the rest of the body.. it exists near the center of the brain but takes its signals from a lense, like a cornea or eye.. it 'sees' it's signals, it's not connected via 'wiring' to the brain... at least that's what i read... if so, doesn't that mean the pineal gland is not really part of us, just sort of trapped in us?

From what i understand the pineal is the master emotional and spiritual gland whereas the pituitary is the master physical body gland. Could it be the pineal is alien while the pituitary is of this world? And can the pineal gland continue to 'live' in some way, stay active perhaps, without the rest of the brain?
