Current Opinion in Neurobiology, 1994
In the past year, our knowledge of neurotransmitter transporters has increased significantly. Recently, new members of two families of plasma membrane uptake carriers have been cloned, and the stoichiometries, physiological function and mechanisms of modulation of some of these transporters are now better understood.

Annual Review of Neuroscience, 1996
Synaptic vesicle exocytosis is rapid and highly localized, which are features that arise from the organization of the presynaptic active zone, where vesicle fusion occurs. Colocalization of calcium channels with the proteins making up the vesicle docking machinery at the active zone, combined with the low affinity and high cooperativity of the calcium ...

Cellular and Molecular Neurobiology, 1990
1. To study physiological roles of substance P (SP), gamma-aminobutyric acid (GABA), enkephalins and other endogenous substances, we developed several kinds of isolated spinal cord preparations of newborn rats. 2. In these preparations, various slow responses of spinal neurons evoked by stimulation of primary afferent C fibers were depressed by a ...

Neurotransmitters as morphogens
1988Publisher Summary This chapter presents considerable evidence for morphogenetic functions of neurotransmitters during embryonic development, a role that may derive from their appearance early in evolution, still evidenced today by their presence in primitive organisms.

Essays in Biochemistry, 1998
NO and CO are small gaseous molecules that can be synthesized de novo in neuronal tissue and can diffuse readily through the plasma membrane. NOS inhibitors prevent the induction of LTP in the hippocampus, and studies with NOS knock-out mice and viral overexpression of mutated NOS indicate that the endothelial form of the enzyme is probably responsible

Nanosensors for neurotransmitters
Analytical and Bioanalytical Chemistry, 2015Neurotransmitters are an important class of messenger molecules. They govern chemical communication between cells for example in the brain. The spatiotemporal propagation of these chemical signals is a crucial part of communication between cells.

Archives of General Psychiatry, 1982
The most predictable anxiolytic effects of neurotransmitters are linked to the activation of a gamma-aminobutyric acid (GABA)-ergic subsystem associated with specific benzodiazepine receptors. Recent studies have indicated that subtypes of benzodiazepine receptors may be associated specifically with anxiolytic actions.

NEUROTRANSMITTERS AND INTRAOCULAR PRESSURE*
Fundamental & Clinical Pharmacology, 1988Summary— The role of the ocular autonomic nervous system in IOP regulation has been well established. Pharmacological and autohistoradiographic studies confirmed the high density of beta2 and alpha2 receptors on ciliary processes and iris epithelium. Their respective pharmacological activation or blockade is discussed.

Neurons send out a multitude of chemical signals, called neurotransmitters, to communicate between neurons in brain, and between neurons and target cells in the periphery. The most important of these communication processes is synaptic transmission, which accounts for the ability of the brain to rapidly process information, and which is characterized ...

Neurotransmitters and cognition
2006Cognition deficits have receivedmuch attention over the last two decades. The severe impairment of cholinergic function in dementias, particularly in age-related cognitive decline andAlzheimer’s disease has been indicated. However, loss of cholinergic activity may play a key role in the cognitive symptoms but it cannot clearly demonstrate the entire ...
