Impact of frequency drift on gamma-aminobutyric acid-edited MR spectroscopy.
PURPOSE To investigate the quantitative impact of frequency drift on Gamma-Aminobutyric acid (GABA+)-edited MRS of the human brain at 3 Tesla (T). METHODS Three sequential GABA+-edited MEGA-PRESS acquisitions were acquired in fifteen sessions; in ten of these, MRS was preceded by functional MRI (fMRI) to induce frequency drift, which was estimated from the creatine resonance at 3.0 ppm. Simul...
متن کاملGamma-Aminobutyric Acid (GABA) Monograpy
Introduction Gamma-aminobutyric acid (GABA) is a major neuro transmitter widely distributed throughout the central nervous system (CNS). Because too much excitation can lead to irritability, restlessness, insomnia, seizures, and movement disorders, it must be balanced with inhibition. GABA – the most important inhibitory neurotransmitter in the brain – provides this inhibition, acting like a “b...
متن کاملReproducibility of prefrontal γ-aminobutyric acid measurements with J-edited spectroscopy.
γ-Aminobutyric acid (GABA) is the chief inhibitory neurotransmitter of the human brain, and GABA-ergic dysfunction has been implicated in a variety of neuropsychiatric disorders. Recent MRS techniques have allowed the quantification of GABA concentrations in vivo, and could therefore provide biologically relevant information. Few reports have formally characterized the reproducibility of these ...
متن کاملEffect of Curcumin on the Hypothalamus Levels of the Potent Inhibitory Neurotransmitter ,Gamma aminobutyric acid
Background: There are some reports in the literature showing that hypothalamus synthesizes and secretes amino acid neurotransmitters. According to several studies, elevated serum levels of gamma-amino butyric acid (GABA), a potent inhibitory neurotransmitter, have recently been implicated in the pathogenesis of neural diseases. The purpose of this research was to estimate the effects of curcumi...
متن کاملP146: Gamma Aminobutyric Acid (GABA) and its Alterations in Stress
Gamma aminobutyrate (GABA) is a non-protein amino acid that is thought to play an important role in the modulation of the central response to stress. Mechanisms by which GABA may facilitate these responses to stress are metabolic and/or mechanical disruptions. Environmental stresses increase GABA accumulation through cytosolic acidification, induce an acidic pH-dependent activation of glutamate...
