To understand how a nerve impulse travels along the neuron, the complete pathway of the neuron must be understood. The impulse is essentially a message that is sent to the brain. More »

Nerve impulses travel directly across connected synapses via electricity, while the impulses use special chemicals to cross non-touching synapses, according to the Science Museum of the South Kensington Museum in London.... More »

Nerve impulses begin with a change in the charge of voltages found in axon walls, which are stimulated by ions moving in and out of the neuron walls. Nerve impulses are formed from a change in voltage, which then creates... More »
