Along the way, we examine some of the major neurotransmitter systems in detail. Of these, I begin with the neurotransmitter that pharmacologist Otto Loewi discovered a couple days after Easter Sunday in 1920 while working at University College, London. His equipment was simple but his insights demonstrated true genius. Loewi shared the Nobel Prize for Physiology or Medicine in 1936 with Henry Dale, also a pharmacologist, for their work on chemical neurotransmission, and so it is fitting that I begin with the focus of this work, acetylcholine.

That “anything” could be a certain drug or a disease. A C A S E I N P OINT : ALZ HEIMER ’S DISEASE Sometimes we can learn much about the role of a particular neurotransmitter system by investigating what happens when it is injured or diseased. In the brains of people with Alzheimer’s disease, for example, acetylcholine neurons that project into the hippocampus and cortex very slowly die. The effects of this neuronal death have been the subject of research in my laboratory for more than 25 years.

At that point, the EEG wave will disappear. This pre wave indicates that you were paying close attention to what you thought was about to happen. It is an expression of your brain experiencing anticipation. Experiments in my laboratory and in others have demonstrated that the appearance of this wave of electrical activity requires the normal function of acetylcholine within your frontal cortex. If the acetylcholine neurons that project into your frontal cortex are destroyed, then this wave cannot fully form and you will have great difficulty paying attention to important things, such as the impending appearance of a masked gunman.
