PSYC-1000 Chapter Notes -Monoamine Oxidase, Electrical Brain Stimulation, Central Nervous System
Document Summary
Surgery and electrical brain stimulation usually last resorts. Often paired with a form of psychological therapy. Figure 16. 6 how psychotropic drugs reach the brain: psychotropic drugs are able to affect one or more neurotransmitters. Protects brain cells from infection and other threats. The neurotransmitters targeted determine which disorders will be responsive to it. Antidepressants: antidepressant drugs: medications designed to reduce symptoms of depression. Target areas of the brain that are rich in monoamine neurotransmitters: when functioning normally, monoamine neurotransmitters = serotonin, norepinephrine, and dopamine. Many different types as each has its own unique way of altering brain chemistry: monoamine oxidase inhibitors (maois): antidepressants that deactivate monoamine oxidase, an enzyme that breaks down serotonin, dopamine, and norepinephrine. Leaves more neurotransmitters available for synaptic transmission. Not used often due to many negative side effects: some are very dangerous, dangerous interactions with other medications and some types of food. Tricyclic antidepressants: drugs that block the reuptake of serotonin and norepinephrine.
