Very happy to see it out! Congrats!!

Cool! Can't wait to read it

Dorsoventral hippocampus neural assemblies reactivate during sleep following an aversive experience - Nature Neuroscience Synchronization of sharp-wave ripples across the dorsoventral hippocampus during sleep supports coordinated reactivation that represents negative experiences more faithfully than positive ones.

Our paper is out today!!! (not an April fool's day joke) Congrats to authors @azulsilva.bsky.social, @belalima-paiva.bsky.social, Ele Pronier, and mostly to the amazing scientist and human being who led this project @facuumm.bsky.social

I’m building a foundational reading list for our lab (systems & circuit neuroscience, compneuro, modeling, neuromodulators, population coding etc.).

I’d like to crowdsource recommendations.

Which review(s) would you consider mandatory reading for the next generation of researchers?

Adaptive communication between cell assemblies and “reader” neurons shapes flexible brain dynamics Cell assemblies have been proposed as key units of brain activity, underlying diverse functions, but their basic features are not well understood. This study shows that interactions between cell assem...

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

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

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.

Study visually captures hard truth: Walking home at night is not the same for women An eye-catching new BYU study shows just how different the experience of walking home at night is for women versus men.

this heat map study of gender differences of walking through urban environments at night is not surprising, but still sort of incredible to see

It's so heartbreaking to see one of the 'three angry old men'* flirting w the idea of bombing a country so nonchalantly.

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. 🧵

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

Thank you Sanja!

The embedding enables a cool experiment: start with a tetrode in CA1 pyr, lower it gradually, and project the signal at each step.
The tetrode follows the predicted path, and the gamma profiles match the silicon probe data beautifully at each step.
See one going from CA1 pyr to DG midmol below!
