Movie Watching for Individual Functional Brain Network Estimation in Adolescents

This study compares functional brain network estimation using resting state crosshair fixation and movie watching in adolescents, finding similar network topography with minor border shifts.

Disentangling Brain-Psychopathology Associations: A Systematic Evaluation of Transdiagnostic Latent Factor Models

This study evaluates transdiagnostic latent factor models for brain-psychopathology associations using neuroimaging data, finding no consistent improvement in predictive utility over summary scores.

Menarche onset is an inflection point for mental health and brain development

The paper identifies menarche as an inflection point for mental health and brain development in adolescent females using longitudinal data.

Charting the brain networks of impulsivity: Meta-analytic synthesis, functional connectivity modelling and neurotransmitter associations

This study investigates the neural correlates of impulsivity using meta-analytic synthesis and functional connectivity modelling, identifying distinct brain networks associated with decision-making and action control.

Success versus failure in cognitive control: meta-analytic evidence from neuroimaging studies on error processing

The paper uses meta-analytic evidence to show brain regions involved in error processing versus successful response in cognitive control tasks.

The Burden of Reliability: How Measurement Noise Limits Brain-Behaviour Predictions

Low phenotypic measurement reliability severely limits out-of-sample brain-behaviour prediction accuracy and prevents models from fully benefiting when neuroimaging sample sizes scale from hundreds to thousands of participants.

A spatiotemporal complexity architecture of human brain activity

This study identifies complexity drops in functional MRI signals as a mechanism linking neural regularity to functional network architecture in the human brain.

Individual Differences in Delay Discounting are Associated with Dorsal Prefrontal Cortex Connectivity in Youth

This study links individual differences in delay discounting to specific patterns of dorsal prefrontal cortex connectivity in youth using resting-state fMRI.

Fingerprinting and behavioural prediction rest on distinct functional systems of the human connectome

This study shows that connectome fingerprints, used to identify individuals, are distinct from neural features predictive of behavior, suggesting they may not be as functionally relevant as previously thought.

Spatially localized fMRI metrics as predictive andhighly distinct state-independent fingerprints

The paper demonstrates that regional homogeneity (ReHo) fMRI metrics can uniquely identify individuals and correlate with intelligence, showing high stability and potential for precision medicine.
