In an EPSP (excitatory postsynaptic potential) , there is a

A) net movement of Na⁺ out of the cells.
B) net movement of Cl⁻ into the cells.
C) decrease in action potential amplitude.
D) local hyperpolarization.
E) local depolarization.

Question

Natsidzirai Madhawu · Accepted Answer

Final Answer : E, Explanation :  EPSPs involve a local depolarization of the postsynaptic membrane, making the neuron more likely to fire an action potential. This is typically due to the influx of positively charged ions like Na+.
