That explains a lot! 😅

Met an old pal at #SfN25, he's still waiting to hear back from reviewer #3

Managed to squeeze in one more head-direction themed get-together in the sun to wrap up #SfN25 🧭☀️🧠

@apeyrache.bsky.social @svenkrausse.bsky.social @anujvadher.bsky.social & Paul Dudchenko

👋 At #SfN25? Interested in how head-direction cells anchor to visual cues?

🧠 Come visit me Tuesday Morning (8am - 12pm)
📍 Poster RR15

showing work w/ @adrian-du.bsky.social on parallax in PoSub and what we learn from it for visual cue integration. Come say hi or DM for a coffee chat! ☕️ #Neurosky

Finally, on Tuesday morning, @svenkrausse.bsky.social from Alpha Renner's group will present a super exciting finding of parallax errors in the head-direction signal that they observed in my PoSub recordings [Board number RR15] [4/n]

Then on Sunday afternoon, @anujvadher.bsky.social will present a late breaking poster on how this Fragile X rat model phenotype may (or may not) translate to impairments in path integration [Board number: LBP110] [3/n]

In the late breaking poster session on Saturday afternoon (i.e. today!) I'll be showing how the head-direction system in the rat model of Fragile X Syndrome fails to perform weighted integration of visual and self-motion cues, likely due to deficits in self-motion coding [Board number: LBP041] [2/n]

Great to be back at SfN in San Diego, even though the weather gods have decided to go full 'Scottish summer' this year 🌧️
If you're here and you're into spatial navigation do check out the posters below 👇 [1/n]

Having a great time at the @flatironinstitute.org CCN software workshop in San Diego! Do check out their fantastic Python packages Pynapple @pynapple.bsky.social (for general neurophys analysis) and NeMoS (for GLM) github.com/flatironinstitute/nemos - they are an absolute pleasure to work with 🤩

A neural state space for episodic memories Episodic memories are highly dynamic and change in nonlinear ways over time. This dynamism is not captured by existing systems consolidation theories …

I wrote a thing on episodic memory and systems consolidation. I hope you all enjoy it and/or find it interesting.

Attentional failures after sleep deprivation are locked to joint neurovascular, pupil and cerebrospinal fluid flow dynamics - Nature Neuroscience Yang et al. show that moments of failed attention we experience after sleep deprivation reflect brief ‘sleep-like’ episodes in the brain, corresponding to a brain- and body-wide event with altered brain activity, pupil size and brain fluid movement.

Dopamine ≠ reward but turns out, also not the learning molecule we thought.

If DA RPE is the emperor, this work SCREAMS it was running naked all the time.

This paper got quite some attention recently. Let's simplify it a bit.

Falling asleep follows a predictable bifurcation dynamic - Nature Neuroscience Li et al. propose a conceptual framework to study the phenomenon of falling asleep based on electroencephalogram data. They show that a tipping point marks the brain’s nonlinear wake-to-sleep transiti...

My co-authors have yet to move to Bluesky, so I'm pleased to announce our latest work has just been published in @nature.com Neuroscience. Amazing work led by Junheng Li, revealing that falling asleep follows a predictable bifurcation pattern #neuroskyence #sleep

Let’s use a good occasion to break my Bluesky shyness 😅 — a new article just came out!
This one goes back to data from the very start of my PhD, and I’m so happy to see it finally published 🧠

A mean-field model of neural networks with PV and SOM interneurons reveals connectivity-based mechanisms of gamma oscillations Classic theoretical models of cortical oscillations are based on the interactions between two populations of excitatory and inhibitory neurons. Nevertheless, experimental studies and network simulatio...

Various theoretical properties derived for gamma oscillations based on canonical E-SOM-PV microcircuit connectivity using mean-field modelling, which moves beyond classic Wilson-Cowan models in important ways

Turns out once you get into ring attractors it's quite hard to give them up... Who knew?!

And thanks so much for all the first-hand linguistic info, super interesting 🤩

This one! L. Llewellyn-Jones is a top Welsh historian and a big proponent of what he calls the 'Persian version' (😉) of classical history... Basically relying more on Persian sources (like the inscriptions in Persepolis) than the super-biased Hellenic accounts. Highly recommended!

Oh Wow! I just read somewhere that the word originates from classical Persian, could it be true?

I actually just finished reading an awesome history book about the Achaemenid dynasty... coincidences abound🙂

New paper from the lab 🚨
Led by Ali Golbabaei, this study explores the how the composition of prefrontal cortical engrams changes with memory age:

Thank you 🙂

Thanks Kadjita!

Thanks Elnaz, fingers crossed 🤞🏻

Thanks Dan, and congrats on your position at Yale! Looks like a good year for Peyrache lab alumini 🧭

A 🍍 spotted in the wild at @edinburgh-uni.bsky.social!

Great crash course on neuro data processing with @pynapple.bsky.social and @spikeinterface.bsky.social delivered by @matthiashennig6.bsky.social, @wulfdewolf.bsky.social and Chris Halcrow. So nice to see both libraries working so well together

You've never seen a Polish word before? 😅

Thanks Flor, hope all is well!!
