		Many neurotransmitters are removed from the synaptic gap, after they have activated their specific receptors, by transport proteins residing in neuronal and glial plasma membranes.
		It is important to remove neurotransmitters from the synaptic gap so that they do not continue to stimulate or inhibit the firing of the postsynaptic neuron.
		Neurotransmitters may be either excitatory or inhibitory; that is, they may be of a type that fosters the initiation of a nerve impulse in the receiving neuron, or they may inhibit such an impulse (more at synapse).

	Neurotransmitter Repletion
		Neurotransmitters are the naturally occurring chemicals inside your body that transmit messages between nerve cells.
		Hinz to formulate “Mixed Neurotransmitter Dysfunction Theory.” Five percent of patients with a given neurotransmitter dysfunction disease are purely a serotonin dysfunction, 5% of patients are a purely catecholamine dysfunction, and the remaining 90% of patients are a mixture of both serotonin/catecholamine dysfunction and lie along a spectrum between the two extremes.
		This implies for the vast majority of patients with a neurotransmitter related condition, the serotonin system and the catecholamine system (dopamine, norepinephrine, and epinephrine) must both function properly for the entire system to be healthy and free of neurotransmitter disease.

	Neurotransmitters : by Ray Sahelian, M.D. how to increase neurotransmitter naturally
		A neurotransmitter is defined as a chemical messenger which is released from the synaptic terminal of a neuron at a chemical synapse that diffuses across the synaptic cleft and binds to and stimulates the post-synaptic membrane.
		Neurotransmitter testing is not a reliable way to determine how a person will respond to a particular medicines or supplement for conditions such as depressions, anxiety, ADHD, etc. Neurotransmitter testing could reveal a neurotransmitter imbalance that would be accurate for that particular time period only.
		Neurotransmitter testing is appropriate in cases of neurotransmitter imbalance or excess such as pheochrmocytoma and other clear cut medical conditions.

		Neurotransmitter testing can be particularly useful in determining which psychotropic medications, if any, would be best suited for a particular patient.
		Through the use of urinary neurotransmitter testing, the doctor was able to identify imbalances that were likely contributing to the patient's problems.
		Urinary neurotransmitter testing provides relevant clinical data for the healthcare provider, allowing for a more informed decision to be made when determining which psychotropic medication is best for the patient.

		Insufficient activity of the neurotransmitters serotonin and norepinephrine is a central element of the model of depression most widely held by neurobiologists today.
		The conceptual case for the effectiveness of neurotransmitter precursors builds upon the idea that depression is a result of an inadequate amount or insufficient activity of one or more neurotransmitters.
		On the other hand, the decision with respect to neurotransmitter precursors and prescription antidepressant drugs is not necessarily a case of "one or the other." Growing numbers of individuals are combining various prescription drugs with alternative treatments, and the ranks of M.D.'s integrating alternative treatments into their practice is increasing.

	Medical Dictionary: Neurotransmitter - WrongDiagnosis.com
		Neurotransmitter: Endogenous signaling molecules that alter the behavior of neurons or effector cells.
		Neurotransmitter is used here in its most general sense, including not only messengers that act directly to regulate ion channels, but also those that act through second messenger systems, and those that act at a distance from their site of release.
		Neurotransmitter : any of a group of substances that are released on excitation from the axon terminal of a presynaptic neuron and travel across the synaptic cleft to either excite or inhibit the target cell; included are neuromodulators, neuroregulators, neuromediators, neurohormones, and neurohumors, whether or not acting at synapses.

		Neurotransmitters found in the urine are not neurotransmitters filtered from the renal arterial blood and excreted into the urine.
		Neurotransmitter lab testing prior to starting amino acid precursors has no value if the goal of treatment is to optimize relief of disease symptoms.
		After reviewing thousands of neurotransmitter lab assays, we have observed that urinary neurotransmitter responses to amino acids (to the right) represent the response of serotonin and dopamine when a dosing change in a serotonin precursor (5-HTP) is given in combination with a dopamine precursor (tyrosine and/or L-dopa).

	Neurotransmitter Precursors
		The neuronutrient food and hence- the makeup of the brain can be altered by tryptophan, tyrosine and choline because they are the precursors of neurotransmitters substances that are released from a neuron or nerve cell when it fires.
