A neurotransmitter which plays an important role in memory. It is used for control of sensory input signals and muscular control. ACh is a stimulatory neurotransmitter. When released by muscle nerves, it makes those muscles contract. It is made from the precursor nutrient choline and there is some evidence that increased dietary choline can increase production and use of acetylcholine.
