The paper examines how childhood maltreatment affects brain structure in 3,711 individuals with MDD and PTSD, finding age- and sex-specific brain morphometric differences.

The paper shows that spontaneous movement suppresses AgRP neuron activity, reinforcing exercise behavior in mice.

The paper models decision-making under uncertainty with qualitative outcomes, showing that quantitative measures can be extracted from qualitative choices and that uncertainty attitudes vary across domains.

This study identifies distinct neural patterns in PTSD patients for traumatic versus sad memories, showing divergent hippocampal representations and symptom severity effects in the posterior cingulate cortex.

This study finds smaller total and subregional cerebellar volumes in PTSD compared to controls using a large dataset and advanced parcellation methods.

This paper compares four methods for harmonizing cortical thickness data across multiple sites and finds that ComBat-GAM is most effective in detecting case-control differences and age-related cortical thinning.

This study examines how PTSD affects neural computations of subjective value under uncertainty using fMRI and a gambling paradigm, finding increased aversion to uncertainty and altered valuation system activity in PTSD patients.

This study identifies hippocampal subfield volume differences in PTSD and depression across 31 cohorts, finding depression has a stronger effect than PTSD, especially in CA1, with comorbid cases showing more pronounced changes.

This study demonstrates that affective flexibility can occur unconsciously, as physiological responses adapt to reversed threat contingencies without conscious awareness of the stimuli.
