The rate at which a neuron fires depends on the number of:
A)Number of terminals of nearby interneurons
B)Relative strength of excitatory and inhibitory inputs it receives
C)Postsynaptic receptors on this neuron
D)Autoreceptors on this neuron

Question

Quizplus · Accepted Answer

The firing of a neuron is determined by the balance of excitatory and inhibitory inputs it receives. If the excitatory inputs exceed the inhibitory inputs, the neuron is more likely to fire, whereas if the inhibitory inputs exceed the excitatory inputs, the neuron is less likely to fire. The number of terminals of nearby interneurons, postsynaptic receptors, and autoreceptors can all have an impact on the overall activity of the neuron, but they do not directly determine the firing rate.
