"WebbThe neurotransmitter can either help (excite) or hinder (inhibit) neuron B from firing its own action potential. In an intact brain, the balance of hundreds of excitatory and inhibitory inputs to a neuron determines whether an action potential will result. Neurons are essentially electrical devices.

WebbNeurotransmitters are chemical messengers that your body can’t function without. Their job is to carry chemical signals (“messages”) from one neuron (nerve cell) to the next target cell. The next target cell can be another nerve cell, a muscle cell or a gland. Your body has a vast network of nerves (your nervous system) that send and ...
