Assume a neuron receives EPSPs and IPSPs from several adjacent neurons. How might that neuron's threshold potential be reached, causing it to produce its own action potential?
A) if IPSPs outnumber EPSPs
B) if IPSPs equal EPSPs
C) if EPSPs outnumber IPSPs
D) if the adjacent neurons contain many axon terminals
E) if the receiving neuron contains many dendrites

Quizplus · Accepted Answer

The neuron's threshold potential is more likely to be reached and generate an action potential if excitatory postsynaptic potentials (EPSPs) outnumber inhibitory postsynaptic potentials (IPSPs), as EPSPs increase the neuron's membrane potential closer to the threshold for firing an action potential.
