41. This process would increase the acetylcholine levels and would have cholinergic effects. 42. Moreover, every nerve that controls that muscles in the body releases acetylcholine . 43. Nicotine mimics the effects of a neurotransmitter called acetylcholine . 44. Perhaps alcohol acts on the same receptor as nicotine, the acetylcholine receptor. 45. The researchers'hypothesis is that acetylcholine promotes the brain's activities. 46. By activating its receptor, acetylcholine directs the cells to stretch and flatten. 47. Dopamine-producing nerve cells have acetylcholine -receptor molecules on their surfaces. 48. The antibodies lock onto the receptors in place of acetylcholine , preventing contraction. 49. All work by raising acetylcholine levels in the brain. 50. Eventually, stored acetylcholine is made available, and the amplitudes increase again.
