It was acetylcholine, the first neurotransmitter discovered, that gave us our initial glimpse of how brain cells communicate. It is a wonderful molecule! Acetylcholine is important for learning and memory. It has also been shown to enter the brain while dreaming.
These solid sterling silver earrings are about one inch long and are attached to sterling silver French ear wires. They come with an info card about acetylcholine in a gift box.
