Information in the form of an electrochemical signal that travels through a neuron in response to a stimulus is called as nerve impulse.

The nerve impulse is an electrical signal that travels down a neuron. This electrical signal transmits commands from the brain to the motor nerves, and carries sensory messages from sensory nerves (skin, ears, nose, eyes, taste buds) to the brain. The transmission of nerve impulses from neuron to neuron is performed by neurotransmitters.
