Types of Neurotransmitters - Nervous System Physiology

 Effects: Some neurotransmitters are excitatory, some are inhibitory, and others exert both effects, depending upon the specific receptor types with which they interact. Actions: Neurotransmitters that bind to and open ion channels are said to act directly. Neurotransmitters that act indirectly tend to promote broader, longer-lasting effects by acting through intracellular second-messenger molecules.
