neurotransmitters

A range of small-molecule chemical substances released by EXOCYTOSIS from a nerve ending on the arrival of a nerve impulse. Neurotransmitters are specific to particular neurons. They interacts with receptors on adjacent structures to trigger off a response, either excitatory or inhibitory. The adjacent structure may be another nerve, a muscle fibre or a gland. The main neurotransmitters are acetylcholine, glycine, glutamate, dopamine, noradrenaline, adrenaline, serotonin, histamine and GABA (gamma-amino-butyric acid). With the exception of the adrenalines all the neurotransmitters are AMINO ACIDS or derivatives of amino acids.

Neurotransmitters

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.

Depression Affected by Many Neurotransmitters

We rarely have enough change in tyrosine levels with normal food, but if you administer it alone, it can increase the production of neurotransmitters.

Food & mood

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.

Chemical, brain may serve as pain thermostat

Neurotransmitters convert the electrical information into chemical information that can cross the synapse and stimulate or inhibit the next neuron (Hyman 2005).

Review: the clinical utility of urinary biogenic amines and other neurotransmitters

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.

Why brain cell communication is so fast

Receptor: A protein usually found on the surface of a neuron or other cell that recognizes and binds to neurotransmitters or other chemical messengers.
