An inhibitory postsynaptic potential

Question

Quizplus · Accepted Answer

[ $\mathrm{VC} 2 \mathrm{~b}$ ]. An inhibitory postsynaptic potential hyperpolarizes the postsynaptic membrane, taking it farther from threshold. Opening $\mathrm{Cl}^{-}$channels would hyperpolarize the postsynaptic membrane by driving the membrane potential toward the $\mathrm{Cl}^{-}$equilibrium potential (about $-90 \mathrm{mV}$ ). Opening $\mathrm{Ca}^{2+}$ channels would depolarize the postsynaptic membrane by driving it toward the $\mathrm{Ca}^{2+}$ equilibrium potential.
