Thrilled to share our lab's first preprint on the neural mechanisms underlying helping behavior in mice! 🧠🐭 We show that dorsal hippocampal networks play a key role in rescuing a distressed peer: biorxiv.org/content/10.110…

🧵 1/8 The Illusion of Thinking: Are reasoning models like o1/o3, DeepSeek-R1, and Claude 3.7 Sonnet really "thinking"? 🤔 Or are they just throwing more compute towards pattern matching? The new Large Reasoning Models (LRMs) show promising gains on math and coding benchmarks,…

This marks my first-author contribution as part of the Maren Lab team! Our findings shed new light on the mechanisms underlying context-dependent extinction of learned fear. Huge thanks to @StephenMaren , @tugcettuna , and @MicTott for teamwork. biorxiv.org/content/10.110…

Fantastic to be part of this unique conference in Pipa, Brazil. Great science, inspiring students and the weather wasn’t bad either. Massive thank you to @_vitorLdS Andressa Radiske, Caro Gonzalez and @RhythmicSpikes for organising. Onwards and upwards for the global south!

Very grateful to have organized the Meeting on Neural Mechanisms of Cognitive Function in Northeast Brazil🇧🇷 with @M_Caro_Gonzalez, @_vitorLdS & @RhythmicSpikes. Unforgettable days of science and connection. Thanks to @IBROorg and the #SimonsFoundation

Check out my preprint on hippocampal ripple diversity, with @_vitorLdS and David Dupret at @MRCBNDU, where we reveal that distinct CA1 laminar profiles of ripples are associated with different reactivation dynamics: doi.org/10.1101/2025.0… #hippocampus

New preprint about SWRs, this time in HUMANS! 🤩 With @MaslarovaAnna & JiyunShin, we’ve (i) developed a pipeline to analyze SWRs in intracranial EEG, and (ii) created ripmap, an open-source toolbox that allows versatile inspection and curation of events 🧵 biorxiv.org/content/10.110…

❗RESEARCH OPPORTUNITIES📷 We're hiring for an ambitious @wellcometrust project exploring brain mechanisms of planning/inference in psychosis 🧠 Multiple scales: from single neurons to human behaviour/fMRI and neural networks. 1 post-doc 1 clinical fellow 👀

Congratulations to Unit postdoctoral researcher Dr Vitor Lopes dos Santos on winning the Director’s Award for Open Research for 2024! mrcbndu.ox.ac.uk/news/vitor-lop… @NDCNOxford @OxfordMedSci @UniofOxford @The_MRC

Want to hear more about hippocampus-to-cortex feedback circuit? Our paper with the Basu lab is out in Nat Neuro! rdcu.be/eak1k . Well done Tanvi Butola!

Step 1: Fire all of the government employees who make air travel safe. Step 2: Let America see the consequences of those actions. Step 3: Outsource the safety jobs he eliminated to his own company. Step 4: Profit. How very expected.

As Elon Musk was reportedly slashing Education Department contracts, SpaceX secured a multimillion-dollar “supplemental” deal from NASA. buff.ly/4hBiNxo

When Big American tech does it, they argue gobbling gigabytes of proprietary data is “fair use”, when someone else does it “against the terms of service”.

There are lots of good reasons why replacing traditional closed book exams with open book ones is a good idea. Framing it to be about “reducing attainment gaps” doesn’t help anyone. telegraph.co.uk/news/2025/01/2…

Researchers paid $8.968 billion for their findings to be freely accessible. 🧵1/10
