Modern psychopharmacology is largely the story of chemical neurotransmission. One must be fluent in the language and principles of chemical neurotransmission to:
Understand the actions of drugs on the brain,
Grasp the impact of diseases upon the central nervous system,
Interpret the behavioral consequences of psychiatric medicines.
When a cell is stimulated or polarized, it fires an action potential. Explain the process and how neurotransmitters are dispersed to other neighboring cells across the synapse.
Explain the concept of a drug’s half-life.
