Document Summary
The scientific field concerned with the discovery and study of compounds that selectively affect the functioning of the nervous system. Examples include acetylcholine, serotonin or dopamine); amino acid neurotransmitters (a neurotransmitter that is itself an amino acid. Gaba, glycine or glutamate); and a wide variety of peptide neurotransmitters (also called neuropeptides. Neurotransmitter systems form a complex array in the brain: Here, the appearance of more than one neurotransmitter in a given presynaptic terminal. Muscarinic receptors can be blocked by drugs atropine or scopolamine, producing pronounced changes in cognition, including drowsiness, confusion, memory problems, and blurred vision. This system is important in reward and reinforcement: abnormalities in the mesolimbocortical pathway are associated with some on the symptoms of schizophrenia. Norepinephrine: the two main clusters of neurons in the brainstem releasing norepinephrine (ne)- which is also called nor adrenaline, it is a neurotransmitter produced and released by sympathetic postganglionic neurons to accelerate organ activity.
