A really cool thing about the gamma pre-SMA result: we found the same effect for negative > positive faces in a recent paper (academic.oup.com/scan/article...). As many before me have said: it is essential to consider how the brain is β€œmoving the body” during emotion processing!

Happy to share a new publication showing stronger theta, alpha, and gamma responses to negative vs positive images. Alpha effects were in several primary and extended visual regions, while gamma effects were in parietal and pre-SMA cortex. See all results -> www.sciencedirect.com/science/arti...

Affective info involves visual and limbic regions, but ALSO systems involved in motor planning.

Oscillatory brain dynamics underlying affective face processing Abstract. Facial expressions are ubiquitous and highly reliable social cues. Decades of research has shown that affective faces undergo facilitated process

NEW paper looking at oscillatory responses to affective faces.

some main findings:
Stronger beta for affective faces across visual regions.
Stronger gamma to angry faces in presupp motor cortex.

Overall, screen time or social media use didn’t β€œmatter”, but specific problematic behaviors. With prior lit, suggests that social media provides more (i.e. constant) opportunity to engage in behaviors problematic to mental health, lead to different trajectories of brain development.

Happy to share a new paper where we show, in later pubertal stages, using social media to make social comparisons relates to 1) weaker extended visual alpha, prefrontal beta power and 2) more symptoms of anxiety and attention problems.
