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 ...

Biofeedback and Self-Regulation, 1990
In this article definitions of stress and distress are proposed and the relationships between stress and activities of neurohormonal systems explored. The idea is developed that stress is a condition where expectations--whether genetically programmed, established by prior learning, or deduced from circumstances--do not match the current or anticipated ...

Neurotransmitters in the retina
Current Eye Research, 1996Processing of visual information within the retina depends in large measure upon a complement of chemical neurotransmitters which are released at synaptic contacts between individual neurons. Numerous investigators have participated in the identification of many of these transmitters and their assignment to specific neuronal subpopulations. However, it

Neurotransmitters in the Brain
1989The brain is the pacemaker of the human body. If this pacemaker does not function life is not possible. In the brain there are more than 10 billion neurons. Each neuron makes more than a thousand contacts. The axons of the neuron branches ramify into several end terminals which are in contact with other cell bodies and dendrites. The propagation of the
