Excitatory Neurotransmitter

An excitatory neurotransmitter is a neurotransmitter chemical whose function it is to "excite" or activate a post-synaptic neuron (a neuron on the far side of synapse) that is conveying an electrochemical signal to the body. The most prevalent excitatory neurotransmitter is glutamate which reacts with 90% of the neurotransmitters in the human brain. This type of neurotransmitter can be viewed as an "enabling" substance that allows other neurotransmitters to rapidly conduct their electrochemical signals to the brain or back to the effected nerves.
