Very excited by our first benchmarking results on BMD by the talented @sargechris.bsky.social! By including control models trained on Kinetics that deal trivially with time (i.e. treating videos as image sequences), we find better brain alignment scores for actual video models in early visual areas!
📢 New preprint!
We benchmark 99 image and video models 🤖 on brain representational alignment to fMRI data of 10 humans 🧠 watching videos!

Exciting new study from @alexatompary.bsky.social and Lila Davachi: consolidation-related restructuring and integration doi.org/10.7554/eLif...
Integration of overlapping sequences emerges with consolidation through medial prefrontal cortex neural ensembles and hippocampal–cortical connectivity
Changes in cortical neural ensembles and heightened coupling between the hippocampus and cortex enable the eventual behavioral integration of memories with overlapping sequential information.
