Amazing day for my first tweet. Super excited to share my PhD research, published today @Nature.

We find that contrary to popular belief, cortical reactivations predict the future rather than reflect the past.

NEW: Mark Andermann (@andermann_mark) of @harvardmed and @BIDMChealth brings experimental data and computational modeling together to understand cortical reactivations. Watch the video:

@Artoftheproblem @andermann_mark @andrewlutas @Oren_Amsalem @richlyn_jesseba @JustinMcMahon_ @JDimidschstein @blsabatini If by intelligence you mean the ability to better discriminate between different things in the world, then the brain seems to be able to do this process offline by pushing representations away from each other, and it seems to already "predict" the best way to do that.

[Nghia Nguyen @NghiaDNguyen]

@larshallenius @andermann_mark @andrewlutas @Oren_Amsalem @richlyn_jesseba @JustinMcMahon_ @JDimidschstein @blsabatini I think the common hypothesis is that the brain is making predictions, and if it is incorrect, an error signal updates the future prediction. For us, the "prediction" is hypothesized to drive brain plasticity directly independent of error signals so it is a little different.

Last May, we had excellent speakers from around the world: @mariaahmedch @ambrosipri @davidhbrann @salwan_butrus @alexbchen @NghiaDNguyen @JOuellette19 speaking at our symposium: https://t.co/xMygSASNyU. We hope you will join the tradition to inspire us and be inspired!

Main @CosyneMeeting is over and 3 (among many) posters I learned from:
1- Cortical reactivations predict future sensory responses. Nguyen, ..., @andermann_mark

2- Mechanisms underlying flexible, context-dependent timing in medial entorhinal cortex. @ErinBigus, ..., @jamesgheys1

[@markandermann.bsky.social @andermann_mark]

Excited to share Nghia Nguyen’s graduate work @biorxiv_neursci!

How do offline stimulus reactivations in cortex relate to later changes in stimulus responses (representational drift)?

Cortical reactivations predict future sensory responses.
