Proposal accepted! It's a proposal to create a one-day trivia contest for @LearnedLeague , but all wins count. If anyone on my twitter is a member, come on July 16th to test your knowledge of ancient roman cuisine.

Our recent paper about the role of the cerebellum as a gateway for the formation of long-term sensorimotor memories is the subject of a story by @thecrimson!

Harvard SEAS researchers found in an August study that the cerebellum is necessary for the formation of new long-term, but not short-term, motor memories. Avi W. Burstein, Bianca G. Ciubancan, and Dionise Guerra-Carrillo report. thecrimson.com/article/2024/…

A recent study examining the kinematics of 3D arm movements in individuals in the sub-acute phase after #stroke found that both weakness and synergy intrusion contribute to motor deficits during the sub-acute period. journals.sagepub.com/doi/ful… #neurotwitter #neurorehabilitation

Our paper – with Tricia Gibo and Maurice Smith – is now out in PNAS! “The Cerebellum acts as the analog to the Medial Temporal Lobe for Sensorimotor Memories”pnas.org/doi/10.1073/pnas.24… An updated #tweetprint:

We found 15 reaching studies examining adaptation after cerebellar damage. While timing data were not available, studies using 4-8 targets– meaning that on average it would take long to revisit the same target – reported >2x impairment than studies that used 1-3 targets. 19/n

I'd like to thank the two (anonymous) reviewers for their constructive feedback, which has definitely strengthened the paper. Special thanks to Sarah Hemminger, @reziliusReza, Amy Bastian, and @herzfeldd for helping us acquire and parse the data. 20/20
