A new drug has its effect at the postsynaptic membrane. Specifically, it opens sodium channels. The effect will be
A)depolarization
B)hyper polarization
C)inhibition
D)to prevent reuptake
E)a more negative resting potential

Question

Quizplus · Accepted Answer

Opening sodium channels in the postsynaptic membrane allows sodium ions to flow into the neuron, causing depolarization. This is because the influx of positively charged sodium ions reduces the membrane potential, making the inside of the neuron less negative compared to the outside.
