WebAn excitatory transmitter promotes the generation an action potential in the receiving neuron, while an inhibitory transmitter prevents it. Modulatory Neurotransmitters can transmit messages to several cells simultaneously and also help to communicate with chemical transmitters. WebNeurotransmitters are chemical messengers used by the nervous system to relay information from one nerve to another. Optimal neurotransmitter balance is required to maintain proper health. Imbalances can cause the brain and the body to be over- or under-stimulated, producing neurological or psychological symptoms. how did girl scout cookies beginNeurons form elaborate networks through which nerve impulses – action potentials – travel. Each neuron has as many as 15,000 connections with neighboring neurons. Neurons do not touch each other (except in the case of an electrical synapse through a gap junction); instead, neurons interact at contact points called synapses: a junction within two nerve cells, consisting of a miniature gap within which impulses are carried by a neurotransmitter.
