Which is true?
-The pineal gland, located within the brain's two hemispheres, receives signals from the SCN and decreases production of the hormone melatonin, which helps put you to sleep once the lights go down. -The pineal gland, located within the brain's two hemispheres, receives signals from the SCN and increases production of the hormone GABA, which helps put you to sleep once the lights go down. -The pineal gland also governs functions that are synchronized with the sleep/wake cycle, including body temperature, hormone secretion, urine production, and changes in blood pressure. -The pineal gland rests in a part of the brain called the hypothalamus, just above the point where the optic nerves cross. Light that reaches photoreceptors in the retina (a tissue at the back of the eye) creates signals that travel along the optic nerve to the pineal gland.
