Neural impulse is a term used to describe the communication between neurons in the nervous system. It occurs when a neuron sends an electrical signal, or action potential, down its axon to the next neuron in the sequence. There are several synonyms for neural impulse, some of which include action potential, nerve signal, neuronal firing, nerve impulse, and synaptic transmission. These terms all refer to the same process of communication between neurons in the brain, which is vital for the proper functioning of the nervous system and the body as a whole. Understanding the different synonyms for neural impulse can help individuals better understand the complex processes that occur within the human brain.
