Cross-state stability and maturational similarity of the social brain connectome in children and adolescents

The paper examines cross-state stability and maturational similarity of the social brain connectome in children and adolescents, finding stronger coupling in the social brain and sex-specific age-related effects.

Short-term memory capacity and chronic stress levels predict cognitive effort choice as a function of reward level and effort demand

The paper examines how short-term memory and chronic stress influence cognitive effort choices under varying reward and effort conditions.

Short-term memory capacity predicts willingness to expend cognitive effort for reward

The paper investigates how short-term memory ability influences cognitive effort deployment for reward in humans, finding it is the strongest predictor compared to depression, stress, and reward anticipation.

Gender impacts the relationship between mood disorder symptoms and effortful avoidance performance

The paper examines how gender influences the relationship between anxiety and depression scores and performance in effortful avoidance and reward-seeking tasks.

Reactivation of hedonic but not sensory representations in human emotional learning

This study investigates what aspects of an unconditioned stimulus are transferred to a conditioned stimulus during emotional learning, finding that hedonic rather than sensory features are reactivated.

Lateralization of autonomic activity in response to limb-specific threat

This study shows that autonomic responses to limb-specific threat are asymmetric, with increased EDA in the stimulated limb, suggesting localized rather than global threat preparation.

Decoding representations of discriminatory and hedonic information during appetitive and aversive touch

This study uses fMRI and pattern component modeling to show that hedonic and discriminatory tactile information are represented separately in the brain, with hedonic touch linked to interoceptive and affective regions.

Affectively biased competition underlying sustained attention is tuned to rewarding expressions and is not modulated by norepinephrine receptor gene variant

The paper examines if individual differences in norepinephrine receptor function influence emotionally biased competition during sustained attention, finding no effect of the ADRA2B gene variant.
