[Boris Bernhardt]

Hi all,

Tamara’s BIC lecture happening in 10 mins.

We also have a zoom link for folks at home https://mcgill.zoom.us/j/83896756724

Best,
Boris

We wondered if this robust level of organization evolved to support resting state patterns, or if functional connectivity during complex processing might reveal different or possibly smoother or “more perfect” gradients.

We compared rest and movie gradients topologically, assessed the test-retest reliability of both, and applied Connectome-based Predictive Modeling (CPM) to test whether movie or rest gradients provide higher predictive accuracies of behavioral measures. Our movie-watching results underscore the hierarchical organization of the brain observed in resting state gradients, but also provide novel information about cortical organization during complex processing. Based on these initial analyses, we suggest that movie gradients may provide useful tools for future work, especially in psychiatric and pediatric populations.

Her lab creates, tests and shares movies to evoke specific symptoms and types of processing during fMRI scanning, with a focus on child psychiatric disorders. She attended medical school and completed residency and fellowship training at Yale University. She is currently an assistant professor at the University of British Columbia, and a clinician scientist at the BC Children’s Hospital Research Institute. In addition to running the Naturalistic Neuroimaging Lab, she continues to practice as a psychiatrist, providing telehealth care for children and families in remote northern BC communities through BC Children’s Hospital.
