0 a chemical that carries messages between neurons or between neurons and muscles
1 a chemical substance that carries messages from one nerve cell to another in the body
Qualitative and quantitative high performance liquid chromatographic analysis of monoamine neurotransmitters and metabolites in cerebrospinal fluid and brain tissue using reductive electrochemical detection.
Environmental experience also can affect brain chemistry by altering neurotransmitter synthesis, transmitter receptor synthesis, and transmitter uptake systems.
Other neurotransmitters affected include acetylcholine, serotonin and noradrenaline, but the role of these substances in the clinical syndrome is uncertain.
Research efforts to prevent delayed emesis have been directed at blocking neurotransmitter receptors in the brainstem's vomiting center.
On the one hand, glia express different types of neurotransmitter receptors, which enables them to respond to neural signals.
Coordination of neural communication and alterations of astroglial neurotransmitter receptor expression could therefore contribute to disturbed catecholamine transmission in mood disorders.
Additional work is necessary to unravel the neurotransmitter, neuromodulatory, and 0or intracellular mechanisms that regulate the triggering and timing of outer segment disk shedding.
Indeed, they must be complementary, as the neurotransmitter systems involved are very different, but both have modulatory or coordinating functions.
