The paper examines pre-stress functional brain connectivity in relation to anxiety during war-related stress and finds lower baseline connectivity between the right nucleus accumbens and right amygdala is linked to higher subsequent anxiety.

This study identifies mood variability and responsiveness to recent events as markers of well-being using computational modeling and a mood modulation task.

This study links trial-by-trial mood dynamics during gambling tasks to neural oscillations in adolescents using MEG, finding beta-gamma power related to reward expectation and localized brain sources.

The paper shows that earlier experiences have a stronger influence on reported mood than recent events, using computational modeling and neural evidence.

This paper reviews reward processing as a cause and predictor of depression, identifies challenges, and finds reward processing abnormalities are not yet clinically predictive but may have causal roles.
