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.
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.....Found on http://en.wikipedia.org/wiki/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....Found on http://antoine.frostburg.edu/chem/senese/101/glossary/n.shtml

[See firstly neurotransmission.] The contents of the synaptic vesicles released from the pre-synaptic neuron into the synaptic cleft. These chemicals induce a post-synaptic potential in the receiving neuron.

A chemical mediator released from nerve terminals in response to nerve stimulation and which binds to receptors which are on the surface of other nerve cells. There are a number of different classes of neurotransmitters as well as many different receptor types and subtypes.
