The paper introduces Osprey-MRSI, an open-source software package for fully automated MRSI data analysis and visualization, validated across multiple vendors and sites.

The paper investigates GABA and Glutamate dynamics along with BOLD signals in psychosis patients with hallucinations during a cognitive task, finding baseline Glx differences and altered BOLD-Glx associations.

This paper develops a model to reduce unwanted variance in GABA-edited MRS data while preserving functional dynamics, showing improved SNR and reduced variability in GABA+ estimates.

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

This paper develops a novel UTE 31P 3D MRSI acquisition and processing pipeline, demonstrating high repeatability across different clinical setups.

This study assesses the intra-individual reliability of 1H-MRS measurements in the anterior cingulate cortex over one year, finding that metabolite levels are reliably quantified with small variability.

This paper demonstrates a method to concurrently measure BOLD and metabolite changes during a cognitive task using fMRS, showing significant Glx increases and moderate BOLD correlation.

The paper compares seven algorithms for modelling GABA-edited 1H-MRS data from 222 subjects across 20 sites, finding moderate agreement and highlighting the need for standardized parameters.

The paper examines how glutamate levels in Heschl's gyrus relate to functional connectivity in auditory networks during unpredictable auditory stimulation.

This study uses diffusion tensor imaging and machine learning to predict brain age in schizophrenia and bipolar disorder patients, finding age overestimation in both groups compared to controls.

The paper shows that neural activity in the ventro-medial frontal cortex precedes conscious awareness of entering or exiting a transient hallucinatory state.
