Could crystal methamphetamine have any physiological effect on this cholinergic synapse given the conditions below:
- No action potential reaches the presynaptic terminal.
- The extracellular Ca²⁺ concentration remains constantly high.
- The Ca²⁺ concentration inside the presynaptic terminal remains constantly low.
- The concentration of acetylcholine (ACh) in the synaptic cleft rises and then falls.
- A postsynaptic potential (PSP) is generated.
- The synapse is a chemical, cholinergic synapse that releases ACh.
