Nature of Glutamate Alterations in Schizophrenia: A Meta-analysis of Proton Magnetic Resonance Spectroscopy Studies.

open access: yesJAMA psychiatry, 2016
IMPORTANCE Alterations in glutamatergic neurotransmission may be fundamental to the pathophysiology of schizophrenia, and the glutamatergic system is a target for novel therapeutic interventions in the disorder.

Magnetic resonance spectroscopy reveals abnormalities of glucose metabolism in the Alzheimer's brain

open access: yesAnnals of Clinical and Translational Neurology, 2018
Brain glucose hypometabolism is a prominent feature of Alzheimer's disease (AD), and in this case–control study we used Magnetic Resonance Spectroscopy (MRS) to assess AD‐related differences in the posterior cingulate/precuneal ratio of glucose, lactate,

Magnetic resonance spectroscopy of an atomically thin material using a single-spin qubit

open access: yesScience, 2017
Getting a sense of atomically thin materials Two-dimensional materials such as graphene and transition metal dichalcogenides provide a powerful platform for optoelectronic applications. As the materials get thinner, however, characterizing the electronic

Elevated brain lactate in schizophrenia: a 7 T magnetic resonance spectroscopy study

open access: yesTranslational Psychiatry, 2016
Various lines of evidence suggest that brain bioenergetics and mitochondrial function may be altered in schizophrenia. On the basis of prior phosphorus-31 (31P)-magnetic resonance spectroscopy (MRS), post-mortem and preclinical studies, this study was ...

Hitchhiker’s Guide to Voxel Segmentation for Partial Volume Correction of In Vivo Magnetic Resonance Spectroscopy

open access: yesMagnetic Resonance Insights, 2016
Partial volume effects have the potential to cause inaccuracies when quantifying metabolites using proton magnetic resonance spectroscopy (MRS). In order to correct for cerebrospinal fluid content, a spectroscopic voxel needs to be segmented according to
