If a Neuron Receives Both Excitatory and Inhibitory Signals, Will

question 38

Multiple Choice

If a neuron receives both excitatory and inhibitory signals, will an action potential be generated?

• A) No, because any inhibitory signals will cancel out the excitatory signals.
• B) Yes, but the action potential will be much smaller than if only excitatory signals were received.
• C) It depends; if more excitatory than inhibitory signals are received, then an action potential may result.
• D) Yes, because excitatory signals always stimulate an action potential.
• E) It depends; if more inhibitory than excitatory signals are received, then the neuron will be free to produce an action potential.
