Neurotransmitters that move the post-synaptic membrane potential closer to threshold are __________.
A) inhibitory
B) excitatory
C) all-or-none
D) hyperpolarizing

Question

Quizplus · Accepted Answer

Excitatory neurotransmitters make the post-synaptic neuron more likely to fire an action potential by moving its membrane potential closer to the threshold, thus having an excitatory effect on neuronal activity.
