Coordinated activity within and differential activity between large-scale neuronal networks such as the default mode network (DMN) and the control network (CN) is a critical feature of brain organization. The CN usually exhibits activations in response to cognitive tasks while the DMN shows deactivations; in addition, activity between the two networks is anti-correlated at rest. To address this issue, we used functional MRI to measure whole-brain BOLD signal during resting-state and task-evoked…

From Molecular to Behavior: Higher Order Occipital Cortex in Major Depressive Disorder.

It is demonstrated that middle temporal (MT) visual area, known to mediate the perception of visual motion, provides a strong candidate for biomarker in MDD, and elevated MT ALFF relates to specifically retardation in behavior as measured by the Hamilton subscore.

Subacute changes in brain functional network connectivity after nocturnal sodium oxybate intake are associated with anterior cingulate GABA/glutamate balance

A placebo-controlled, double-blind, randomized, cross-over pharmacological magnetic resonance imaging study with a nocturnal administration of GHB, combined with magnetic resonance spectroscopy of GABA and glutamate in the anterior cingulate cortex, allowing to identify a neural pattern of pharmacological modulation of the SN, which may serve as a neurobiological signature of the wake-promoting effects ofGHB.

Human brain functional MRS reveals interplay of metabolites implicated in neurotransmission and neuroenergetics

An up-to-date overview of fMRS research in the last three decades is provided, both in terms of applications and technological advances.

A Resting-State Functional MR Imaging and Spectroscopy Study of the Dorsal Hippocampus in the Chronic Unpredictable Stress Rat Model

It is demonstrated that susceptible- and non-susceptible subjects show differential alterations in hippocampal GABA and glutamate metabolism that, in turn, associate with changes in functional connectivity, consistent with previously reported stress-induced metabolomic changes that suggest overall neurotransmitter dysfunction in the hippocampus.

Aging alters the mediating effect of endogenous GABA on the interaction between functional connectivity and motor-state transitions

Age-related alteration of the preferred state of endogenous GABA concentration may reflect a generic compensatory mechanism allowing for higher temporal precision in neural tuning and maintaining a higher behavioral functioning level.

Neurochemical and brain functional changes in the ventromedial prefrontal cortex of first-episode psychosis patients: A combined functional magnetic resonance imaging—proton magnetic resonance spectroscopy study

The results indicated that ventromedial prefrontal cortex functional connectivity changes were positively correlated with higher local GABA+ level in first-episode psychosis patients and altered neurochemical concentration and functional connectivity provide insights into the pathology of schizophrenia.

Reductions in rostral anterior cingulate GABA are associated with stress circuitry in females with major depression: a multimodal imaging investigation

Findings indicate that reduced GABA in females with MDD was associated with connectivity differences within and across key networks implicated in depression.

Perceived Stress, Cortical GABA, and Functional Connectivity Correlates: A Hypothesis-Generating Preliminary Study

A relationship between perceived stress and GABAergic functioning in DLPFC, a core node of the CEN, an intrinsic network thought to underlie goal-directed attentional processes is supported and may inform treatment strategies to improve outcomes in stress-related conditions.

Does an Over-Connected Visual Cortex Undermine Efforts to Stay Sober After Treatment for Alcohol Use Disorder?

The increased across-community interaction of the ventromedial PFC and the visual cortex in relapsers at timepoint 1 may be an early indicator for treatment failure in a subgroup of AUD patients.

GABA, Glutamate and Neural Activity: A Systematic Review With Meta-Analysis of Multimodal 1H-MRS-fMRI Studies

A systematic review and meta-analysis of available studies examining the relationship between 1H-MRS glutamate and/or GABA levels and task-related fMRI signal in the healthy brain found converging evidence of negative associations between GABA Levels and local brain activity and positive associations between glutamate levels and distal brain activity, outside of the 1H -MRS sampling region.



Resting-State Glutamate and GABA Concentrations Predict Task-Induced Deactivation in the Default Mode Network

Results demonstrate significant associations of glutamate and GABA with DMN deactivation, and high regional GABA concentration in the PCC/PCu area is associated with enhanced deactivation induced by the task in the same region, whereas high glutamate concentration isassociated with reduced deactivation.

Coupling of functional connectivity and regional cerebral blood flow reveals a physiological basis for network hubs of the human brain

A tight coupling between blood supply and brain functional topology during rest and its modulation in response to task demands is indicated, which may shed light on the physiological basis of human brain functional connectome.

Baseline GABA concentration and fMRI response

Neurotransmitter changes during interference task in anterior cingulate cortex: evidence from fMRI-guided functional MRS at 3 T

Using fMRI-guided functional magnetic resonance spectroscopy to measure metabolite/BOLD associations during a cognitive task at 3 T, an association between induced inhibitory neurotransmitter increase and BOLD changes was observed.

Increase in glutamate/glutamine concentration in the medial prefrontal cortex during mental imagery: A combined functional mrs and fMRI study

Glx concentrations in the medial prefrontal cortex increased during the imagery task, as compared to resting‐state periods preceding and following the task, contributing to the understanding of the biochemical basis of generating or manipulating mental representations and the MPFC's role in this.

Resting GABA concentration predicts peak gamma frequency and fMRI amplitude in response to visual stimulation in humans

The results are supportive of recent theories suggesting that these functional neuroimaging metrics are dependent on the excitation/inhibition balance in an individual's cortex and have important implications for the interpretation of functional imaging results, particularly when making between-group comparisons in clinical research.
