Atypical attentional network dynamics in adolescent depression during emotional movie viewing.

ABSTRACT: Emotion studies have commonly reported atypical emotional processing in clinically depressed adolescents in the context of short-lasting emotional cues. However, interindividual differences in the moment-to-moment brain network dynamics that underlie this impaired emotional reactivity remain unclear, and the use of poorly matched controls and relatively small sample sizes represents major limitations in most neuroimaging depression studies to date. Here, we address these concerns by using the temporal features of a rich naturalistic paradigm (i.e. a clip from the movie 'Despicable Me') to investigate brain network dynamics in 42 clinically depressed and 42 nondepressed adolescents aged 16-21 years, matched for age, gender, and psychiatric comorbidities.
