Even if depression starts with a single abnormal
neurotransmitter, things that happen afterward turn it into a multisystem disease, at least as far as serotonin and the hypothalamic-pituitary-adrenal axis are concerned," said Dr.
We rarely have enough change in tyrosine levels with normal food, but if you administer it alone, it can increase the production of
neurotransmitters.
In a larger sense, the experiment suggests that
neurotransmitters like serotonin play a dual role in pain - passing messages between individual nerve cells, but also modulating the general level of responsiveness of the entire system.
Serotonin is a
neurotransmitter in the brain that is thought to play a key role in controlling depression.
Neurotransmitters convert the electrical information into chemical information that can cross the synapse and stimulate or inhibit the next neuron (Hyman 2005).
An electrical signal causes the containers and membrane to fuse and the
neurotransmitters flow from the nerve ending to be captured by other nerve cells.
Receptor: A protein usually found on the surface of a neuron or other cell that recognizes and binds to
neurotransmitters or other chemical messengers.
Serotonin (5-HT): Reduced levels of this
neurotransmitter within the brain are associated with feelings of depression, aggression, irritability, anxiety and despair.
The effect of polychlorinated biphenyls on the uptake of dopamine and other
neurotransmitters into rat brain synaptic vesicles.
Inhibition of reuptae allows buildup of
neurotransmitters in the synapse and activation of the auto-receptors, leading to a decrease in firing activity, said Dr Blier.
Neurotransmitters are chemicals that permit the passage of signals within the brain.
Serotonin, famed as the target of Prozac and other antidepressants, acts as a
neurotransmitter, relaying signals from one brain cell to the next.
