A [а] is а smаll, lоcalized change in membrane pоtential that оccurs in response to a stimulus. If the change is positive and brings the neuron closer to threshold, it is called an [b], whereas a negative change that moves the neuron further from threshold is called an [c]. Multiple signals can combine through [d], and if the threshold is reached, an [e] is generated, allowing the neuron to send a signal down the axon.
