Imagine a neuron that has several hundred axonal knobs impinging on it. The majority of these axonal knobs are shown to be "firing." However, the neuron in question does not transmit an impulse. Give a valid explanation of why this could occur.
What will be an ideal response?
Both excitatory and inhibitory potentials impinge on neurons. Inhibitory postsynaptic potentials (IPSPs) are "firing," but due to the neurotransmitter released and its action, the postsynaptic neuron is inhibited from "firing" (hyperpolarized).
