Intersubject representational similarity analysis uncovers the impact of state anxiety on brain activation patterns in the human extrastriate cortex

This study uses ISRSA to show state anxiety modulates extrastriate cortex activity in response to emotional images, revealing a brain-behavior association through multivariate analysis.

Heroes and villains: opposing narrative roles engage neural synchronization in the lateral inferior frontal gyrus

The paper examines neural synchronization in the default mode network during the appearance of protagonists and antagonists in movies, finding higher synchronization in the inferior frontal gyrus and orbitofrontal cortex for protagonists.

Topographical similarity of cortical thickness represents generalized anxiety symptoms in adolescence

The paper identifies a cortical thickness topography in adolescents associated with generalized anxiety symptoms using inter-subject representational similarity analysis.

Similarity in Functional Connectome Architecture Predicts Teenage Grit

The paper shows that grit in teenagers is linked to similar functional connectome architecture across individuals and stability within individuals.

Meta-analytic activation maps can help identify affective processes captured by contrast-based task fMRI: the case of threat-related facial expressions

The paper compares meta-analysis maps (MAMs) of emotion categories with individual contrast maps (ICMs) from task fMRI data to identify affective processes related to threat-related facial expressions.

A connectome-wide functional signature of trait anger

This study identifies brain connectivity patterns associated with trait anger using a large sample and connectome-wide analysis, finding hyperconnectivity in action-related regions.

Amygdalostriatal coupling underpins positive but not negative coloring of ambiguous affect

The paper investigates how amygdala activity integrates contextual cues with facial expressions to determine valence, finding that amygdalostriatal coupling supports positive but not negative affective integration.

Maternal Overprotection in Childhood is Associated with Amygdala Reactivity and Structural Connectivity in Adulthood

This study finds that higher maternal overprotection in childhood is linked to increased amygdala reactivity to explicit threat signals and reduced structural integrity of the uncinate fasciculus in young adulthood.

Microstructural integrity of white matter moderates an association between childhood adversity and adult trait anger

The paper examines how white matter microstructural integrity moderates the link between childhood adversity and adult trait anger using diffusion MRI data.

General Functional Connectivity: shared features of resting-state and task fMRI drive reliable and heritable individual differences in functional brain networks

This paper introduces General Functional Connectivity (GFC) to improve reliability and heritability of intrinsic connectivity estimates by combining resting-state and task fMRI data.

Corticolimbic circuit structure moderates an association between early life stress and later trait anxiety

The paper examines how structural features of the corticolimbic circuit moderate the link between childhood adversity and trait anxiety in young adults.

Paradoxical Associations Between Familial Affective Responsiveness, Stress, and Amygdala Reactivity

The paper examines how subtle variations in caregiving, specifically familial affective responsiveness, influence amygdala reactivity to interpersonal threat in adolescents, revealing paradoxical associations with stress levels.

Trajectories of Alcohol Use Initiation and Risk to Develop an Alcohol Use Disorder During Adolescence: A Role for Stress and Amygdala Activity

The paper identifies two trajectories of alcohol use initiation in adolescents and links early initiation to increased risk of AUD, stress, and amygdala reactivity.
