Objectives :
Objectives Identify the main neurotransmitters of the central nervous system (CNS), and summarize some of their main physiologic effects.
Discuss the significance of the blood-brain barrier in the context of how it allows or prevents the effects of drugs in general.
Describe how, in many cases, control of key activities in the CNS involves more than one neural pathway, each with its own neurotransmitter and set of receptors. This is generally important for understanding much of the specific information presented in later chapters in this unit.
