Altered markers of brain metabolism and excitability are associated with executive functioning in young children exposed to alcohol in utero

This study identifies altered brain metabolites in children with prenatal alcohol exposure linked to executive functioning and excitability.

Linewidth-related bias in modelled concentration estimates from GABA-edited 1H-MRS

This study investigates how linewidth and SNR affect GABA+ concentration estimates from MRS data using six modelling algorithms, finding significant associations with Lorentzian linewidth.

Harmonisation of multi-site MRS data with ComBat

This paper applies ComBat to harmonize multi-site MRS data, revealing biological effects obscured by site and vendor differences.

Changes in brain metabolite levels across childhood

The paper examines age-related changes in brain metabolite levels in children aged 2-11 years using MRS, finding age-related increases and decreases in several key metabolites in specific brain regions.

NIfTI-MRS: A standard format for magnetic resonance spectroscopic data

The paper introduces NIfTI-MRS, a standardized format for magnetic resonance spectroscopy data to improve sharing and integration across the MRS community.

Intolerance of uncertainty is associated with heightened responding in the prefrontal cortex during instructed outcome uncertainty of threat

The paper examines how intolerance of uncertainty relates to neural responses in the prefrontal cortex during uncertain threat scenarios.

GABA AND GLUTAMATE CHANGES IN PEDIATRIC MIGRAINE

This study measures GABA and glutamate levels in children with migraine using MRS, finding lower glutamate in the visual cortex and associations between metabolite levels and migraine characteristics.

Effects of Transcranial Direct Current Stimulation on GABA and Glutamate in Children: A Pilot Study

This study examines the effects of tDCS on GABA and glutamate levels in children's brains, finding increased glutamate in the HD-tDCS group but no changes in GABA.

Orbitofrontal and Thalamic Influences on Striatal Involvement in Human Reversal Learning

This study uses fMRI and PPI analysis to show that striatal connectivity with lateral orbitofrontal cortex and CM-Pf thalamus differs in their association with speed and quality of reversal learning in humans.

Regional Striatal Cholinergic Involvement in Human Behavioural Flexibility

This study shows that dorsal striatal choline levels are linked to reversal learning performance in humans, supporting the role of the cholinergic system in behavioural flexibility.
