Our analyses revealed tripartite associations between anxiety symptoms, participants descriptions of the movie, and brain activity in insula, default mode, and dorsal attention regions. These findings underscore the utility of movie paradigms in research on subjective emotional experiences. 2/2

Patients with and without anxiety watched an anxiety-inducing movie during fMRI. Afterward, they provided open descriptions of the movies. Their responses underwent natural language processing to quantity semantic content. 1/2

Outside my expertise, but I'm interested to know the SNR of the CMR02 measurement. Looks highly variable, even more so than BOLD.

A great week of meetings and presenting in Melbourne, including a visit to @orygen.org.au hosted by @sidchop.bsky.social & Lianne Schmaal. Now off to Brisbane for #OHBM2025. I'll be presenting Tuesday and Wednesday, 9am in the Great Hall both days :)

Social anxiety may be related to physical avoidance of aversive stimuli in an interactive game. Our latest study, led by @purnimaqamar.bsky.social. osf.io/preprints/ps...

Check our latest work ‘Linking Subjective Experience of Anxiety to Brain Function using Natural Language Processing’. Our analyses link movie-evoked brain activity and subsequent interview recordings in a pediatric sample with and without anxiety disorders (doi.org/10.31234/osf...).

Our report on "The Relations Among Anxiety, Movie-Watching, and In-Scanner Motion" is out now in Human Brain Mapping. In short: even anxiety-evoking movies reduce pediatric in-scanner movement compared to 'rest', highlighting its benefit for developmental neuroimaging. doi.org/10.1002/hbm....

Update on our study into movie-evoked changes in brain-heart coherence: in addition to suspenseful vs non-suspenseful movie clips, we've now added a contrast to 'rest' which further supports the idea that anxiogenic movie-watching might reduce brain-heart coherence. osf.io/preprints/ps...
