neurotransmitter

A substance found in chemical synapses that is released from the presynaptic terminal in response to depolarization by an action potential, diffuses across the synaptic cleft, and binds a ligand-gated ion channel on the postsynaptic cell. This alters the resting potential of the postsynaptic cell, and thus its excitability. Examples: acetylcholine, GABA, noradrenaline, serotonin, dopamine. See Table N1. ...

Neurotransmitter

Neurotransmitters are endogenous chemicals that transmit signals across a synapse from one neuron (brain cell) to another `target` neuron. Neurotransmitters are packaged into synaptic vesicles clustered beneath the membrane in the axon terminal, on the presynaptic side of a synapse. Neurotransmitters are released into and diffuse across the syna.....

neurotransmitter

Neurotransmitters are molecules that are used to carry signals from one neuron to another. One neuron releases the neurotransmitter near another neuron's receptors. The neurotransmitter diffuses across the gap between the neurons and locks into a receptor site on the surface of the downstream neuron. This induces a change in the downstream neuron....
