Multi-vendor standardized sequence for edited magnetic resonance spectroscopy
Saleh, Muhammad G.; Rimbault, Daniel; Mikkelsen, Mark; Oeltzschner, Georg; Wang, Anna M; Jiang, Dengrong; Alhamud, Ali; Near, Jamie; Schär, Michael; Noeske, Ralph; Murdoch, James B; Ersland, Lars; Craven, Alexander R.; Dwyer, Gerard Eric; Grüner, Renate; Pan, Li; Ahn, Sinyeob; Edden, Richard A.E. (Peer reviewed; Journal article, 2019)Spectral editing allows direct measurement of low-concentration metabolites, such as GABA, glutathione (GSH) and lactate (Lac), relevant for understanding brain (patho)physiology. The most widely used spectral editing ... -
New Approaches to the Use of Magnetic Resonance Spectroscopy for Investigating the Pathophysiology of Auditory-Verbal Hallucinations
Dwyer, Gerard Eric (Doctoral thesis, 2019-10-09)Magnetic resonance imaging (MRI) may be considered one of the most useful technological developments in the field of cognitive neuroscience. Above the ability to provide detailed anatomical images, MRI has afforded researchers ... -
No Effects of Anodal tDCS on Local GABA and Glx Levels in the Left Posterior Superior Temporal Gyrus
Dwyer, Gerard Eric; Craven, Alexander R.; Hirnstein, Marco; Kompus, Kristiina; Assmus, Jörg; Ersland, Lars; Hugdahl, Kenneth; Grüner, Renate (Peer reviewed; Journal article, 2019-01-08)A number of studies investigating the biological effects of transcranial direct current stimulation (tDCS) using magnetic resonance spectroscopy (MRS) have found that it may affect local levels of γ-aminobutyric acid (GABA), ... -
Simultaneous Measurement of the BOLD Effect and Metabolic Changes in Response to Visual Stimulation Using the MEGA-PRESS Sequence at 3 T
Dwyer, Gerard Eric; Craven, Alexander R.; Beresniewicz, Justyna; Kazimierczak, Katarzyna Anna; Ersland, Lars; Hugdahl, Kenneth Jan; Grüner, Eli Renate (Journal article; Peer reviewed, 2021)The blood oxygen level dependent (BOLD) effect that provides the contrast in functional magnetic resonance imaging (fMRI) has been demonstrated to affect the linewidth of spectral peaks as measured with magnetic resonance ...
