Basic Concepts of Neurotransmission

Pediatric Clinics of North America, 2011
An understanding of synaptic neurotransmission is fundamental to the understanding of various neuropsychiatric symptoms and disorders. It is also essential to the discovery of pharmacologic agents that modulate neurotransmission to alleviate such symptoms and conditions.

Effects of Cannabinoids on Neurotransmission [PDF]

, 2005
The CB1 cannabinoid receptor is widely distributed in the central and peripheral nervous system. Within the neuron, the CB1 receptor is often localised in axon terminals, and its activation leads to inhibition of transmitter release. The consequence is inhibition of neurotransmission via a presynaptic mechanism.

Metabolism and Neurotransmission [PDF]

, 1983
Oxidative metabolism is essential for normal neuronal function. The brain consumes 20% of the oxygen that is used by the body even though it represents only 2% of the total body mass. Most of this oxygen is utilized for the catabolism of glucose and the production of ATP.

Dementia and neurotransmission

International Congress Series, 2002
Abstract We investigated the influences of subcortical projections on the cerebral cortex in regard to glucose metabolism using positron emission tomography (PET) with F-18-labeled fluorodeoxyglucose (FDG). We speculate that not only cholinergic but also noradrenergic, serotonergic or dopaminergic projections onto the cerebral cortical neurons may be

Chemical Neurotransmission

2008
Publisher Summary This chapter presents a discussion on chemical neurotransmission and role of chemical neurotransmitters in the prefrontal cortex. It begins with an introduction to neurotransmitters and neurotransmitter receptors. Cells produce certain chemical substances called neurotransmitters and neuromodulators that, through specific receptors ...

Neurotransmission in Hepatic Encephalopathy

1990
After a careful characterization, a rat model of fulminant hepatic failure galactosamine-induced was utilized in order to evaluate the neurochemical changes and the histological alterations which occur during the developing of the encephalopathy. Following these studies, normal rats were treated with toxins claimed to be the primary agents of hepatic ...

Roles of glutamine in neurotransmission

Neuron Glia Biology, 2010
Glutamine (Gln) is found abundantly in the central nervous system (CNS) where it participates in a variety of metabolic pathways. Its major role in the brain is that of a precursor of the neurotransmitter amino acids: the excitatory amino acids, glutamate (Glu) and aspartate (Asp), and the inhibitory amino acid, γ-amino butyric acid (GABA).

Neurotransmission und Neuromodulation

2012
In diesem Kapitel werden die Besonderheiten des zentralen und peripheren Nervensystems bezuglich der Wirkmechanismen von Arzneimitteln besprochen. In diesem Sinne beschaftigt sich dieser Abschnitt mit der Synthese und Degradation, der prasynaptischen vesikularen Speicherung sowie der Freisetzung und Wiederverwertung von Transmittern.

Purinergic Neurotransmission and Neuromodulation

Annual Review of Pharmacology and Toxicology, 1983
Conflicting views abound on the peripheral neurotransmitter and neuromodulator roles of purine compounds. Substantial organ- and species-related variations have become apparent. There is, however, a body of compelling evidence for such roles, if not so broad and ubiquitous as those envisioned (7) for the central nervous system.
