Brain morphological pattern is associated with the presence, severity, and transition of transdiagnostic psychiatric disorders in preadolescents

In 8,672 ABCD preadolescents, one canonical-correlation-derived brain morphology variate links higher cognition with lower psychopathology and tracks cumulative psychiatric diagnoses and 2-year diagnostic transitions.

Physiological Arousal as a Predominant Source of Individual Differences in Functional Brain Networks

This paper identifies physiological arousal as a major source of individual differences in functional brain networks, showing strong correlations between arousal and network properties across multiple sessions and samples.

Human striatal population state dynamics

The paper identifies human striatal population states resembling canonical SPN states and shows their modulation by task demands, arousal, and behavior using fMRI data.

Maturation of Dorsal Association Tracts during Preadolescence Links to Concurrent and Future Cognitive Performance and Transdiagnostic Psychopathology

This study links WM maturation in preadolescence to cognitive performance and future psychiatric disorders using normative models of brain age.

In vivo disentanglement of diffusion frequency-dependence, tensor shape, and relaxation using multidimensional MRI

This paper introduces an efficient in vivo MD-MRI protocol for whole-brain imaging and demonstrates its feasibility and robustness using phantoms and human scans.

The temporal organization of corticostriatal communications

The paper uses fMRI temporal-unwrapping to analyze corticostriatal communication timing, finding distinct temporal organization of node-pair coactivation patterns.

Dissociable misconfigurations of striatal functional connectivity profiles in smokers

The paper identifies distinct misconfigurations of striatal connectivity profiles in smokers, revealing trait and state-specific alterations linked to nicotine dependence severity.

Not all smokers are alike: The hidden cost of sustained attention during nicotine abstinence

The paper identifies two smoker subgroups based on task performance during a cognitive challenge and shows only one subgroup exhibits attention deficits during nicotine abstinence.

Brain Functional Connectome Defines a Transdiagnostic Dimension Shared by Cognitive Dysfunction and Psychopathology in Preadolescents

The paper identifies a functional connectome pattern linked to cognitive dysfunction and psychopathology in preadolescents, showing heritability and predictive power for psychiatric disorders.

Connectivity profile laterality in corticostriatal functional circuitry: a fingerprinting approach

The paper quantifies functional connectivity profile laterality in corticostriatal circuits, identifies laterality hotspots, and shows their predictive value for language task performance.

Nicotine dependence (trait) and acute nicotinic stimulation (state) modulate attention but not cognitive control: converging fMRI evidence from Go-Nogo and Flanker tasks

This study examines how nicotine dependence and acute nicotine stimulation affect attention and cognitive control using fMRI during Go-Nogo and Flanker tasks, finding modulations in attention but not cognitive control.

Habenular and striatal activity during performance feedback are differentially linked with state-like and trait-like aspects of tobacco use disorder

This study dissociates habenula activity linked with nicotine withdrawal from striatal activity linked with addiction severity using pharmacological fMRI.
