This is the strongest ephys evidence so far for a generative model in the brain that I know of. Congratulations @WadiaVarun! Wonderful collaboration with @UeliRutishauser on science that could only be done in humans. And please check out Fig. 5FG. This is new since biorxiv and really surprised me: the mean response to imagery and viewing is actually the same & there are many cells that respond only during imagery--challenging the idea that signal strength is what distinguishes reality from imagination.

Episodic memory encoding fluctuates at a theta rhythm of 3–10 Hz dlvr.it/TRFjmP

Congratulations Thomas! I had the pleasure of watching the project come to fruition since the beginning of my PhD and it (along with relevant discussions) had a big impact on how I view the cognitive neuroscience of memory. And I'm equally excited about our iEEG collaborations!

Congratulations to our SNL 2025 Award Recipients: Esti Blanco-Elorrieta, David Poeppel, and Jacob Momsen! 👏 Learn more about their upcoming Award Lectures at #SNL2025, see: 2025.neurolang.org/awards-in…

(1/6) Thrilled to share our triple-N dataset (Non-human Primate Neural Responses to Natural Scenes)! It captures thousands of high-level visual neuron responses in macaques to natural scenes using #Neuropixels. Link: biorxiv.org/content/10.1101/…

“All of Canada’s major cities rank highly on all safety and livability indices, but Montreal has that certain je ne sais quoi that sets it apart.” Montreal named among safest cities in the world for travel in 2025 cultmtl.com/2025/02/montreal…

Damn it 🙈I thought I was the first to invent this (plus some basil). Is there still chance to co-write a methods paper?

New manuscript published! ✍️👀 Concept neurons evolve from index neurons through overlapping memories. Check it out here: cell.com/trends/cognitive-sc… 1/15

Such a cool study!

Ever wondered what pupil size can tell us about our sleep? In our new work we show that pupil size dynamics correspond to macrostructure and microstructural events in human sleep, and also influences our response to auditory stimulation (video). biorxiv.org/cgi/content/shor…

A fitting fan for Fan et al. 2025!

Toronto Pearson is aware of an incident upon landing involving a Delta Airlines plane arriving from Minneapolis. Emergency teams are responding. All passengers and crew are accounted for.

Cool @ScienceTM study showed it’s possible to incorporate LED lights into flexible cortical electrodes, thus allowing direct visualization of brain activity during intra-operative functional mapping. science.org/doi/10.1126/scit…

What a treat to start the new year with a new paper from the lab, with @azayhara ! @hongyu_chang and Wenbo Tang found that pupil dynamics in naturally sleeping mice uncover a microstructure of sleep that organizes different types of memory replay: nature.com/articles/s41586-0…

It’s time for THE charger. Today, the USB-C becomes officially the common standard for charging electronic devices in the EU. It means better-charging technology, reduced e-waste, and less fuss to find the chargers you need. #DigitalEU

Human cortical pyramidal neurons are larger, exhibit more complex branching patterns, and feature distinctly nonlinear biophysical properties compared to rat cortical pyramidal neurons. Do these unique characteristics make human neurons more functionally complex? Would that enhance the capability of the human brain to perform complex computational tasks? Is this what makes us human? In our new preprint (see below) with @danielayoeli, @DavidBeniaguev, Christiaan de Kock, @mikilon, and @Segev_Lab we use deep learning to tackle these questions by comparing the complexity of neurons’ input-output (I/O) functions using our newly developed Functional Complexity Index (FCI) tool.

🎉Finally published @PLOSCompBiol ! Why do neurons use low-frequency oscillations for encoding? Why not use higher frequencies for better sampling resolution? We identify a speed-precision trade-off driven by noise, showing that theta (3–8 Hz) maximizes bits/s! Check it out 👇

This is a case of ethnic bias due to tribalism. Where is the data showing that, proportionate to population, Chinese students commit more scientific fraud than Portuguese students, or compared to students from 100 other countries? If you can’t provide the data, it’s prejudice.

In a dynamic world, items appear, disappear, and reappear within seconds. In our latest preprint we show: the reappearance of maintained items guides the prioritization of non-reappearing memory items. biorxiv.org/content/10.1101/…

🧠 A story about the brain, told through self-supervised learning: Grid cells, known for mapping physical spaces, also appear to track *abstract spaces* like ideas and sounds. How? 🤔 Excited to share the first of 2 papers at #NeurIPS2024! With @SarthakChandra @FieteGroup. 1/n
