The pineal gland, located in the center of the brain and roughly the size of a grain of rice, is an evolutionary remnant of a real eye that existed 500 million years ago; it contains the same light-sensing proteins as the retina, produces melatonin to regulate sleep cycles, and is the only structure in the human brain that is not split into two halves.

👁️ You Have a Third Eye Inside Your Brain #shorts #science追加:
You have a third eye. It is real. It is in the center of your brain. It is called the pineal gland. It is the size of a grain of rice. 500 million years ago, it was a real eye on top of your head. Lampreys still have it. Tuatara lizards still have it with a lens and a retina. Visible through the skin of their skulls. In humans, it sank inward as our eyes moved to the front. Today, it still contains the same light-sensing proteins as your retina. It controls when you sleep by making melatonin. It is the only single structure in your brain not split into two halves. Follow for more.
