| How does an impulse work/travel? |
|
Definition
| It travels by tiny bursts of electrical power. When an outgoing message reaches the end of the axon, the axon releases a special chemical called a NEUROTRANSMITTER, and the message jumps the sapce between neurons (called a SYNAPSE) and continues traveling along the dendrites of the new neuron. |
