Document Summary
Amino acids are the most common class of neurotransmitter found in the brain. Almost all forebrain synaptic communications are accomplished by one of these neurotransmitters. Glycine - major inhibitory neurotransmitter in the spinal cord and hindbrain. *named after the drugs that are specific agonists to each receptor. Excitotoxicity: neural injury such as stroke may cause excess release of glutamate, which is toxic to neurons. *gaba will always give you an inhibitory effect. Released in all parts of axon terminal, not just active zone. Endorphins: endogenous opioid peptides. (same as what heroin and opines bind to) The gas nitric oxide (no), differs from other neurotransmitters. Does not follow the rules needed to be a neurotransmitter; special case. Produced in locations other than the axon terminal- mainly in dendrites, and diffuses as soon as it is produced, rather than released. Serves as a retrograde transmitter because it works backwards by diffusing back into the presynaptic neuron.
