New preprint! Statistical structure skews object memory toward predictable successors. Model simulations show how this bias can arise from the backward expansion of hippocampal representations. w/co-first Cody Dong, @MarlieTandoc & @AnnaSchapiro

🌟 Cai Lab @Nature paper alert! In new work led by @mysteriousjoe_, we find that rest periods after learning not only stabilize new memories BUT ALSO integrate new memories with older ones from days past! (1/9) Read it here: https://t.co/Ur8dbGfuP3

What do artificial and biological vision have in common? Shared architectures? Shared task objectives? In this preprint, we suggest a more general explanation: they share universal dimensions of natural image representation.
Why do varied DNN designs yield equally good models of human vision? Our preprint with @michaelfbonner shows that diverse DNNs represent images with a shared set of latent dimensions, and these shared dimensions turn out to also be the most brain-aligned. https://t.co/vtOOYHQb47

New paper out! We show how children really are little sponges, learning to the same extent regardless of whether we tell them to focus or not! And the fact that @MarlieTandoc managed to see this through from her lab-manager days will forever impress me!!

Children sometimes learn distracting information better than adults do, perhaps because of the development of selective attention. To understand this potential ...

📣 New paper with @mariam_s_aly and @ChrisBaldassano! We show that consolidation improves memory for temporal structure and makes multistep predictions more efficient but less perceptually detailed! Read more here:

Many experiences unfold predictably over time. Memory for these temporal regularities enables anticipation of events multiple steps into the future. Because tem...

Sad to be missing CCN myself, but @neuro_zz is there! Go check out this new project we are very excited about tomorrow!
Excited to present new work w/ @AnnaSchapiro at #CCN2024! On Thursday, I will present results showing that, through meta-learning, properties resembling distinctions across the neocortex-hippocampus hierarchy emerge in ANNs [Poster B89]

How are multiple interconnected memories reactivated during #sleep? We've published our opinions, but here I'd like to highlight recent findings from other groups. Tl;dr: multiple memories can be (almost) simultaneously reactivated & shared contexts drive this reactivation 1/8

📢The latest from talented @SAbbaspoor 's PhD is out in @cellreports! You into ensembles (@DiagBiochips DA or #neuropixels in #nhp)? ❤️CA1 microcircuits? Wonder why we don’t know how they support #memory or behavior in #primates? Like inhibitory cell types? Cell Assemblies in😴?
Excited to share that the latest @perpl_lab paper is published in @CellReports. We describe the dynamics of superficial and deep CA1 pyramidal cells and identified putative groups of inhibitory cells in freely moving, thinking, and sleeping macaques. 1/n

We are hiring 2 RAs in the AML (now at University of Oregon) with an anticipated start date of late summer/early fall. I promise it will be a fun place to study motivation, affect, and memory! Find more info about the position in the ad below, and a link to apply in the thread.

Excited to share new work @icmlconf by Loek van Rossem exploring universal aspects of representation learning Why is it that large, complex models often learn similar representations? And why might these be similar to the brain? How can we understand this theoretically? (1/11)

Turns out we learn from imagined experiences via an endogenous prediction error! Complementary behavioral, computational & neural evidence in this #preprint by awesome lab alumna @aroma_dabas, w/@rasmusbruckner & @HeidrunSchultz. https://t.co/SrkgksEdlr
@MPI_CBS @CUPsychandNeuro
Excited to finally share the preprint of the major study of my PhD! 🥳 With @rasmusbruckner, @HeidrunSchultz and @rg_benoit , we investigated whether we can learn from imagined experiences much the same way that we learn from actual experiences. 1/5 https://t.co/fGDdJe2S6v

Super excited to share this one, out now in J Neuro! Memory reactivation during sleep does not act holistically on object memory. Led by the amazing @lizsiefert!!
Out now in J Neurosci! Using real-time TMR, we find that sleep reactivation transforms memories, improving certain memory features at the cost of others. W/ Sindhuja Uppuluri, Jianing Mu, @MarlieTandoc, @JamesWardAntony, @AnnaSchapiro
