What happens if the correct ligand binds to ligand-gated sodium channel in a post-synaptic neuron?
A) An excitatory post-synaptic potential occurs.
B) A second-messenger ion channel opens.
C) A signal crosses an electrical synapses.
D) An inhibitory post-synaptic potential occurs,

Question

Quizplus · Accepted Answer

When the correct ligand binds to a ligand-gated sodium channel in a post-synaptic neuron, an excitatory post-synaptic potential (EPSP) occurs. This means that the membrane potential of the neuron becomes more positive, bringing the neuron closer to reaching its threshold for firing an action potential.
