Repeated Viewing of a Film Clip Changes Event Timescales in The Brain Many everyday experiences share a recurring structure: routines, familiar routes, rewatched films, and replayed songs. How do repeated encounters with such structure alter the brain’s representations ...

How do the brain’s event representations change as we gain familiarity with an experience?

Brain regions’ representations can become coarser or finer as events become familiar. Slow-timescale structure predicts memory.

How does the cerebellum contribute to cognitive functions? The role of the cerebellum in motor functions is well understood. But why is the same circuitry engaged in functions such as working memory, language, and social cognition? This Unsolved Mystery…

Why is the #cerebellum (known for coordinating motor functions) also engaged in #cognition? @diedrichsenjorn.bsky.social & @actlab.bsky.social investigate the problems that have made it so difficult to answer this question and outline strategies to make progress. 🧪 #NeuroSky

New paper alert! 🚨

We found that the brain's compass is remarkably stable at two scales

1️⃣ the system maintains its internal organization for weeks
2️⃣ It "remembers" its orientation for weeks, even after a single visit

This may be key to how the brain aligns its other maps.

We test the link between serial dependence (as an index of continuity) and event boundaries (indexing segmentation). A few key findings in the thread:

Building compositional tasks with shared neural subspaces Nature - The brain can flexibly perform multiple tasks by compositionally combining task-relevant neural representations.

Thrilled that my paper is out in the @nature.com. We explored how the brain builds complex tasks by compositionally combining simpler sub-task representations. The brain flexibly performs multiple tasks by dynamically reusing neural subspaces for sensory inputs and motor actions

A unifying account of replay as context-driven memory reactivation A context-driven memory model simulates a wide range of characteristics of waking and sleeping hippocampal replay, providing a new account of how and why replay occurs.

Really thrilled that this paper led by @neurozz.bsky.social is now published in its final version in @elife.bsky.social!!

This is a memory-focused (as opposed to RL-focused) account of the detailed characteristics of forward and backward awake and sleep replay!

Sleep pressure and slow-wave-rich NREM sleep exert distinct effects on cerebral vasomotion and on brain pulsations driven by respiratory and cardiac forces. Heightened sleep pressure (following 35 h of wakefulness) promotes vasomotion (yellow box). Slow-wave-rich NREM sleep enhances brain pulsations driven by the respiratory and cardiac cycles—more so in gray and white matter than in the ventricles (red boxes). The respiration- and cardiac-driven brain pulsations also intensify with deeper sleep (N3 > N2) and correlate with EEG delta power, which is a measure of slow-wave activity (light vs. dark red boxes).

Sleep supports brain health partly by regulating fluid dynamics to clear waste. @ulvlarsen.bsky.social &co probe the relation between #sleep & fluid movement in the human #brain, finding that #SleepPressure & intensity have distinct effects on brain pulsations @plosbiology.org 🧪 plos.io/3XQWCL6
