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. It is likely that the neural mechanisms underlying threat perception - like most behaviors studied - involve a number of different neurotransmitter systems. This is the first study linking the expression of astroglial neurotransmitter receptor to the health of an experimental animal. Such parallel findings point to an intimate relationship between the neurotransmitter systems targeted by drugs and the circadian rhythms targeted by chronotherapeutics. Expanded ontogeny of neurotransmitters and their metabolites in the brains of fetal and newborn lambs. Theoretically, the change in any neurotransmitter component could play a decisive role in the micturition problems of older people. Coordinated transitions in neurotransmitter systems for the initiation and propagation of spontaneous retinal waves. This is done by preventing the accumulation of electrolytes and neurotransmitters in the extracellular space and by releasing gliotransmitters that can act on adjacent neurons.
