Electrical responses of neurons (modifications of the electrical potential across their membranes) may be local (restricted to the place that received the stimulus) or propagated (may travel through the neuron and its axon). Propagated electrical impulses are termed action potentials. Neurons communicate with each other at synapses by a process called synaptic transmission.
