Imagine two people standing in the same spot, looking at the same Goya. They inspect exactly the same parts of the painting, but in a different order. Later, they talk about what they saw. Ignoring all other differences: are the memories they formed identical?

(1/2) I’m starting a NeuroAI and comp neuro lab at the University of Toronto! How do brains and AI learn from ongoing experience? How do they connect delayed outcomes to past actions, adapt to change, and retain what matters? Recruiting funded PhD students for Fall 2027. Links in the reply 👇

Paper accepted at Imaging Neuroscience! Watch this space for links to the final open-access version. Also, thank you to the commenters on the original post--we incorporated some of your suggestions, which I think made for a better paper.

In honor of International Left-Handers Day, we have an updated preprint on scanning left-handed participants in fMRI studies. Although they're 11% of the population, we routinely screen LH people out of fMRI studies due to concerns about functional lateralization 1/n www.biorxiv.org/content/10.1...

How do 🐁deal with complex landscapes? Turns out they learn a lot very quickly. We think they do this by learning a set of repeated sparse paths, which form a type of compressed world model. Joint work with the Hermundstad lab, led by Tzuhsuan Ma and Alison Comrie: www.biorxiv.org/content/10.6...

A new paper from my PhD work! Attention reshapes how the cortex represents meaning. Does the same thing happen in the cerebellum?

🚨 HyperTools 1.1 is out! 🚨 This is our group's Python library for working with and visualizing high-D data. v1.0 was a ground-up rewrite; 1.1 fixes lots of bugs and adds some fun/useful new features and better data handling. pip install --upgrade hypertools Read on for a tour! 🧑‍💻

Hi all, I'm happy to announce that I have started at the University of Oregon as an assistant professor! My group will use computational methods to study learning and synaptic plasticity. I will be hiring grad students this year--please reach out if you're interested! colinbre@uoregon.edu

Our postdoctoral researcher Mengcun Gao studies how we build a picture of the world out of the patterns in our experience 🧠 How do learners pick out what matters, organize what they find, and generalize beyond what they've directly seen? She'll be presenting at #psynom26 in November!

The rich get richer in visual processing: latest study with @ivntmc.bsky.social shows that we allocate resources preferentially to stimuli that we feel confident in estimating, which makes us better at estimating them...even if the initial confidence was misplaced. doi.org/10.1038/s415...

Tomić et al. show that an internal sense of confidence—acting as an intrinsic reward—similarly biases attention,…

How do philosophers and scientists of mind actually work together, and where does the collaboration break down? ISPSM is launching In Conversation, a new online series that aims to bring philosophers and scientists together to work through questions like these. 📅 23 Oct 2026, 1pm BST/8am EDT

Our paper is out in Nature Communications! In our messy, noisy world, do you find planning difficult/less worthwhile? It's not just you. As we increased the stochasticity in a planning environment, we found that people spent less effort planning: www.nature.com/articles/s41... #cogsci #planning

New lab preprint! @khoudary.bsky.social presents a tour-de-force: a new model of how uncertain expectations should help resolve uncertain sensations, supported by re-analysis of four experiments in monkeys (behavior, ephys) and humans (behavior, fMRI, EEG, intracranial) @meganakpeters.bsky.social

how does memory support perceptual decisions made under uncertainty? this question has scaffolded my entire PhD, and I'm so excited to share part of it in this ✨new preprint ✨ w/ @meganakpeters.bsky.social and @aaronbornstein.bsky.social! link: www.biorxiv.org/content/10.6...

2 yrs ago, I briefly laid out a new theory of how motivation works (AGH). Here, I expand on the problems AGH was trying to solve, why they are hard to solve, what my solution looks like, and how this should change our understanding of thoughts & actions. osf.io/preprints/ps... 🧵A few highlights:
