I am excited to share my first paper, showing that episodic memory formation is theta rhythmic, is now published in Nature Human Behavior! Check it out here: rdcu.be/e6pzS. Thanks to my PI, Katherine Duncan, and to my collaborators for their support on this journey! Stay tuned for iEEG follow up 🧠
New paper out from the Duncan Lab in Nature Human Behaviour! Congratulations to lead author Thomas Biba @tbiba.bsky.social for all his hard work through the peaks and troughs, seeing this through to publication!
Big thanks to our collaborators!

Yes it was a sucky one indeed.
New paper alert! 🚨
We found that the brain's compass is remarkably stable at two scales
1️⃣ the system maintains its internal organization for weeks
2️⃣ It "remembers" its orientation for weeks, even after a single visit
This may be key to how the brain aligns its other maps.

🚨 new work from the lab on how eye movements 👀 versus orofacial movements influence 🐭 visual cortex activity 🧠 #neuroscience #behavior #neuroAI
13% success rates at #CIHR, is a really 87% fail rate for>4000 scientists. At a time when 🇨🇦 is investing millions to recruit more scientist into a broken funding environment. 🇨🇦, U need a strong science foundation 2 attract success. #CIHR, fix your science foundation, it is eroding in real time

Tough relationship to manage 😐
New eLife paper is out! We explore the link btw 2-phase perception/generation learning methods like wake-sleep, and what may happen in the brain under on psychedelics. Turns out hallucinations are consistent with hijacking phasic learning, essentially running both wake and sleep phases at once.
Are you thinking about doing neuroscience outreach but want to make it more exciting or hands on?

Wonderful and inspiring opening session at the CIFAR/TWCF Winter School for the Neuroscience of Consciousness, here in beautiful wintery Montebello, in Quebec. All of the participants gave 60 second intros to themselves and their interests. What a great group of people.

In this piece for @thetransmitter.bsky.social, I argue that ecological neuroscience should leverage generative video and interactive models to simulate the world from animals' perspectives.
The technological building blocks are almost here - we just need to align them for this application.

🧠📢 New preprint alert
Large-scale ephys is exploding but spike sorting remains the computational bottleneck. A 2-hr, 6-probe Neuropixels 2.0 Quad Base session can take over a week to sort on a single machine. Here's a better solution. 🧵

Lossy WavPack compression (up to 7× reduction) has minimal impact on sorting accuracy. This offers major storage savings without sacrificing quality.
Conceptual Roadmap of the present study. To examine the relationship between the metabolic costs of visual processing and aesthetic pleasure, we used both computational and physiological measures to quantify metabolic costs during visual processing: 1. Model-derived estimates of metabolic costs based on the activation of a deep neural network; 2. Metabolic activity of human brains, specifically in the visual processing areas. We found that both measures were inversely related to aesthetic pleasure.
Energy efficiency drives evolution, and humans may have evolved pleasure-based signals to optimize actions. Does this extend to aesthetic pleasure?
Yes!

A study in Nature Communications identifies BNST theta and prefrontal BNST coherence as intracranial biomarkers predicting depression outcomes after deep brain stimulation. Lower activity predicted better long-term benefit, linking brain circuits to emotional bias and anxiety. 🧪
