Experiment description
Explore the nerve impulse through an interactive 3D simulation that shows how the body sends messages. A nerve impulse is a small electrical signal that travels through nerve cells to carry information around the body. When you decide to move or respond to something, these signals travel from the brain through the spinal cord and along motor nerves. As they move, the signal changes between electrical and chemical forms to pass from one nerve cell to another. This rapid communication allows the body to move, think, feel, and react in just fractions of a second.
