Humor me: I’m reactivating the latest preprint from the lab (itza “new” trace) 🤓

Come to U10 U11 this morning if you’re interested in NHP cell assemblies, memory replay, wireless recording 100s of units during learning of new and old context-specific sequences, all in freely moving (and sleeping) monkeys #sfn2024

New paper shows causal effects of gaze-contingent stimulation on learning feature-based attention: Treuting et al. (2025) Adaptive Reinforcement Learning is causally supported by Anterior Cingulate Cortex and Striatum. Neuron cell.com/neuron/fulltex… 1/2

🌟 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: nature.com/articles/s4158…

I am and have been fascinated with how memories are formed and stored. A big challenge, not unique to memory, is synthesizing concepts across scales of anaylsis - from molecules to computation. Here I try to distill how we can move forward in understanding memories. Thanks /1

What makes memories last—dynamic ensembles or static synapses? | The Transmitter: Neuroscience News and… disq.us/t/4r3afea Thanks to @JasonSynaptic for organizing!

The best event of #SFN2024 or maybe ever. ticketweb.com/event/pavlovs-…

New research from @perpl_lab sheds light on the circuit organization that supports memory and spatial cognition. 🧠 This discovery helps with our understanding of how our brains process complex cognitive tasks. 🔗 Read the full study here 👉 cell.com/cell-reports/f…

New Paper in @CurrentBiology! Chimpanzees across FIVE communities take rapid turns in gesture-to-gesture exchanges resembling human conversational patterns. Language may not be a pre-requisite for fast-paced, coordinated communication in social species sciencedirect.com/science/articl…

Women are consistently under-cited in neuroscience. @anne_churchlandand and @FDavatolhagh share tools that can help assess citation diversity. thetransmitter.org/publishing/wom…

Cortical interneurons learn on the job! Speculated this was true a decade ago! @JJSherryWU and @artofbiology finally provide evidence! biorxiv.org/content/10.110…

Monumental new work from the @GeorgeDragoi2 lab tackles the question of how replay can parallelize, bind, and compress representations of 15 (!) unique linear track experiences: nature.com/articles/s4159…

Excited to see this out @NeuroCellPress: authors.elsevier.com/a/1jRiE3BtfH9A… We report on a meeting about internal world models in humans, animals, and AI putting Marr's three levels into action across species. @UniFreiburg @IMBIT_UniFR @BrainworldsFR @ThomasBrox @VlachosLab @m_schoenauer

Beautiful. We need more of this! Also newer Kilosort v’s created some issues as it solved others- @SAbbaspoor applied a system of manual curation after KS here; cell.com/cell-reports/f…

This is the first large-animal paper using all DBC deep array probes, but won’t be the last. If you’re into high density sampling (eg #neuropixels, scrolls, etc), and are considering good options for deep/indwelling/wireless/linear recordings, feel free to reach out!

Our MEG/MRI study from @TheCHBH points to subcortical regions involved in alpha modulation: If your left compared to right globus pallidus or caudate are larger, you can better modulate left than right hemisphere alpha power. doi.org/10.7554/eLife.… @eLife

I will stop posting about cycle lanes in Glasgow soon, I promise. But while this news is out there, it's also worth reflecting on just how many people are now using this. Up to 1,500 a day, in all weathers. 13% of journeys on Vicky Rd now are by bike. Change like this matters.
