How does presynaptic calcium cause potentiation?
a. It lingers in the synaptic cleft without being cleared away,
resulting in sustained activation of the postsynaptic cell.
b. It is thought to activate proteins associated with NT vesicle
exocytosis.
c. False! Calcium does not cause potentiation; it only causes
facilitation.
d. It enters the cell through NMDA receptors and lead to insertion
of more AMPA receptors to the postsynaptic membrane.
