A neural impulse is an electrical signal that travels along the axon of a neuron, as a result of the movement of ions across the neuron’s membrane. This electrical signal is generated in response to a stimulus that the neuron has received. When the stimulus is strong enough, it triggers the opening of ion channels in the neuron’s membrane, allowing positively charged sodium ions to rush into the neuron. This surge of positive charge depolarizes the neuron, creating an electrical signal or an action potential. This electrical signal travels down the axon due to changes in membrane potential, and when it reaches the end of the axon, it triggers the release of neurotransmitters into the synaptic cleft between that neuron and another. This chemical signal then propagates to the next neuron, and the process repeats. Thus, neural impulses play a crucial role in the communication between neurons that underlies all aspects of nervous system function, including sensation, perception, movement, and cognition.
