Cell assemblies are drawing increasing attention in neuroscience, but one could argue that they are just an epiphenomenon. Is the activity of cell assemblies relevant for the brain? The short answer is yes. The long answer is in our paper, now online at PLOS Biology. 🧵👇 1/10 doi.org/10.1371/jour...

Happy to announce the 2nd Hippocampus Green Meeting 📍 Barcelona, Spain 🗓️ May 11–12, 2026 Organized together with Manu Valero, Lisa Roux and Dan Bendor 🎤 Keynotes: Nachum Ulanovsky & György Buzsáki ‼️ Call for abstracts now open 🔗 hippocampusgreen.net/wp/ #HippocampusGreen

1) This is a great idea. 2) I would be happy to mentor a project like this. If you want to do a project eg at the intersection of Philosophy of Science and NeuroAI, please feel free to reach out to discuss, or just put my name as a suggested mentor!

Interested in doing a PhD on how #psychedelics (or other psychoactive substances) impact psychological or social processes @durhampsych.bsky.social ? Have a look at the NINE DTP scheme, now open. DM me if interested.

Thrilled to announce I'll be joining the Division of Neuroscience at @manchester.ac.uk as a Lecturer in Feb '26! The DuLab will explore how the brain integrates sensory streams into internal maps 🌐 using the rodent head-direction circuit, the 'neural compass', as a starting point for the journey 🧭

Spread the word! 🗣️🎙️ Together with @azulsilva.bsky.social and Bluesky-less Magdalena Miranda, supported by @elife.bsky.social, we’re organizing a webinar bringing together people working in science communication and outreach. Please, feel free to share the flyer with anyone who might be interested!

This is beautiful work and quite the discovery. This also plays nicely with the idea that superficial place cells are rigid and deep are flexible. Seems to suggest that the flexibility is more about past rep's integrating with newer rep's, than the opposite.

The naturalist Jane Goodall died today at 91. Hope, she argued, is not merely “passive wishful thinking” but a “crucial survival trait.” Revisit a conversation with Goodall, from 2021: nyer.cm/F55JtsS

I’m pleased to share our new paper, “Hippocampal ripple diversity organizes neuronal reactivation dynamics in the offline brain”, out in @cp-neuron.bsky.social ! With @vitorlds.bsky.social and David Dupret, we show that diversity in ripple current profiles shapes reactivation dynamics

The Sosa Lab website is now live! www.sosaneurolab.com We will be seeking a postdoctoral researcher to join the growing team! If you are a rodent neuroscientist and interested in doing systems neuro work in the mountains 🏔️, please check out the "Join" page.

1/ 🚨 New preprint! 🚨 Excited and proud (& a little nervous 😅) to share our latest work on the importance of #theta-timescale spiking during #locomotion in #learning. If you care about how organisms learn, buckle up. 🧵👇 📄 www.biorxiv.org/content/10.1... 💻 code + data 🔗 below 🤩 #neuroskyence

Proud to take on this challenge: building the new Centro de Neurociencias Cajal @institutocajal.bsky.social into a space where neuroscience crosses boundaries and transforms how we understand the 🧠!!

Going to open an escape room where hippocampus researchers have to solve riddles without using space as an explanation for everything

Our collaboration - from PhD work - examining input-specific (EC L3) contributions to rate and temporal coding in CA1 place cells is now out in @natcomms.nature.com 🔬🧠 rdcu.be/evWtz

I know it’s popular to think of citations as attribution of credit, but a part of me also likes to think of them as a trail of fun breadcrumbs for someone 20 years in the future.

this heat map study of gender differences of walking through urban environments at night is not surprising, but still sort of incredible to see news.byu.edu/intellect/st...

It's so heartbreaking to see one of the 'three angry old men'* flirting w the idea of bombing a country so nonchalantly. Like 90million ppl are at the mercy of the 'noise' in his drift diffusion process--is it accumulating to this bound or that bound😞 *see this: www.theguardian.com/commentisfre...

It's officially published!! In my main postdoc work with @markplitt.bsky.social and @lgiocomo.bsky.social, we found that the hippocampus simultaneously encodes an animal's spatial position and its experience relative to reward in parallel population codes. 🧵 www.nature.com/articles/s41...

My latest Aronov lab paper is now published @Nature! When a chickadee looks at a distant location, the same place cells activate as if it were actually there 👁️ The hippocampus encodes where the bird is looking, AND what it expects to see next -- enabling spatial reasoning from afar bit.ly/3HvWSum

I'm pleased to share our new work, “Spatio-temporal organization of network activity patterns in the hippocampus”, out in @cp-cellreports.bsky.social ! With Demi Brizee & David Dupret, we track how oscillations and spiking behaviour map onto hippocampal layers using an LFP-based embedding. (1/13)

🧠🍄Have you used classic or non-classic #psychedelics? We are running an anonymous online study on how these experiences relate to mental processes. Share your experience (takes less than 15 min):👉 durhamuniversity.qualtrics.com/jfe/form/SV_...

Does publishing serve science or is science serving publishing? Damian Pattinson and I (@elife.bsky.social) argue scientific publishing has evolved into a system that, rather than facilitate scholarly communication, distorts and dictates it. onlinelibrary.wiley.com/doi/10.1002/... #OpenScience

I made this figure panel size guide to avoid thinking about dimensions every time. Apparently this post is going to be a 🧵! So feel free to bookmark it and save some time of yours.

This is not to be missed. You’ll spend your day trying to make RNNs psychotic. And we’ll pay you for it!

Talk 17: @smikulovic.bsky.social talking about how he work led in her lab about neural mechanisms underlying #helping in mice. Such a unique research direction. looking forward to her talk. 🤓

Given all that is going on consider this quote from Bertram Russell's 1930 book The conquest of Happiness: “The man who can be interested in the structure of atoms or the way in which a beetle navigates, is likely to get a joy in life which no amount of success in the pursuit of power can give. ”

Great work by @c0rr34m.bsky.social, @smikulovic.bsky.social and colleagues.
