چکیده
►Figure 2: Summed H spectrum acquired during stimulation (A) and rest (B) periods (n=5, NT=56) were subtracted to yield the difference spectrum (C). An additional line broadening (*) of 0.35Hz was applied to the activated spectrum to correct for the BOLD effect on metabolite linewidth (D).

Are glutamate and lactate increases ubiquitous to physiological activation? A 1H functional MR spectroscopy study during motor activation in human brain at 7 Tesla
Recent studies at high field (7Tesla) have reported small metabolite changes, in particular lactate and glutamate (below 0.3μmol/g) during visual stimulation. These studies have been limited to the visual cortex because of its high energy metabolism and good magnetic resonance spectroscopy (MRS) sensitivity using surface coil. The aim of this study was to extend functional MRS (fMRS) to investi...
متن کاملEvaluation of Sensitivity and Reliability of Functional MR Spectroscopy Using Virtual Titration
Introduction Functional magnetic resonance spectroscopy (fMRS) has been used to investigate the activation-related metabolic changes of neurons following stimulation [1]. One of the most critical challenges in fMRS is the extremely tiny signal change, no matter originating from blood-oxygenation level dependent (BOLD) line narrowing [2] or stimulation-induced alteration in metabolite concentrat...

Stimulation period Fig.1 A representative 7T proton spectrum from a single subject:(A) averaged spectrum acquired at rest; (B) averaged spectrum acquired during stimulation; (C) difference between (A) and (B). The peaks seen at 2.01, 2.10, 2.35 and 3.03ppm in the difference spectrum are attributed to linewidth changes due to the BOLD effect as well as concentration changes of metabolites. (D) s...
متن کاملFunctional Magnetic Resonance Spectroscopy: The “New” MRS for Cognitive Neuroscience and Psychiatry Research
Proton magnetic resonance spectroscopy (1H MRS) is a well-established technique for quantifying the brain regional biochemistry in vivo. In most studies, however, the 1H MRS is acquired during rest with little to no constraint on behavior. Measured metabolite levels, therefore, reflect steady-state concentrations whose associations with behavior and cognition are unclear. With the recent advanc...

Introduction. Current proton magnetic resonance spectroscopy (H-MRS) techniques have allowed several researchers to measure changes in glutamate (Glu) concentrations in studies of brain function . Coupled with improved reliability for gamma-amino-butyric acid (GABA) 7 using H-MRS to measure changes as a result of brain activity provides a novel window on brain function 1 which should be of inte...
