Which situation is most likely to lead to the depolarization of a postsynaptic neuron

Question

Quizplus · Accepted Answer

Depolarization occurs when the number of excitatory postsynaptic potentials (PSPs) is greater than the number of inhibitory PSPs. This means that there is a net positive charge entering the postsynaptic neuron, which leads to depolarization and potentially an action potential. Reuptake (A) refers to the removal of neurotransmitters from the synapse, which would not lead to depolarization. Similarly, the release of neurotransmitters (B) does not necessarily lead to depolarization unless there are enough excitatory PSPs to cause depolarization. The presence of inhibitory PSPs (D) would actually prevent depolarization, as they would make the neuron more negative and less likely to fire an action potential.
