Which of the following statements correct describes IPSP? A)It is produced by increased Na⁺ permeability and K⁺ permeability. B)It is produced by increased K⁺ permeability or increased Cl^- permeability. C) It is a small depolarization of the postsynaptic neuron. D) It is produced by increased Na⁺ permeability only.

Question

Quizplus · Accepted Answer

IPSP (inhibitory postsynaptic potential) is a hyperpolarization of the postsynaptic neuron, which is produced by the opening of either potassium (K⁺) or chloride (Cl^-) channels. Option A and D are incorrect because they mention increased Na⁺ permeability, which actually leads to EPSP (excitatory postsynaptic potential) formation. Option C is also incorrect as IPSP is a hyperpolarization, not a depolarization.
