    Hi! So excited to share our newest w : Predictive Representations in Hippocampal & Prefrontal Hierarchies. fMRI evidence that predictive representations are organized at multiple scales in posterior-anterior hierarchies in PFC & hippocampus. 1/N

    Fenn, my nearly 4 year old daughter, recorded her first ever solo song today. She came up with all the words herself and I helped her a little bit with the tune. It’s called ‘Dinosaurs in Love’. 🦕❤️🦕

    Today I will be teaching my undergrad course "How to build a brain from scratch" for the 2nd year running. I've put the materials online - include a document with all lecture slides and notes, which is about as long as a decent novel. Enjoy!

    I get asked how to extract facial features (action units, gaze) from face videos but most solutions involve some technical setup (Docker, SDKs). Now, this Colab notebook extracts them from any Youtube video and you don't need to install a single thing on your laptop.

    This is an eggregious case of other-race bias “they all look alike” If the BBC can make this mistake with Kobe & LeBron, that gives you a sense of how common this is with normal people. This has a big impact on eye-witness identification in court cases

    Within a month of the discovery of the Wuhan coronavirus, the has generated an assay for the virus and made the protocol publicly available to the world. This is an outstanding example of the importance of publicly funded scientific infrastructure!

    Very excited about our new paper: "Ventromedial prefrontal cortex compression during learning". vmPFC coding akin to goal-directed dimensionality reduction and tracks attention weights from learning models.

    Dual* first* author papers: did you know you can cite them throughout your paper as Jane, John et al. (2019)? copyeditors just did that for our proofs. Yay! This is what I call true shared first authorship. how about same in ?

    There has been lots of recent interest in how the might provide a domain general hippocampal . e.g. great reviews by and others In this new commentary I question the how universal such a map would be:

    Recent findings suggest the brain uses domain-general encoding to structure experiences based on distance or similarity. Yet the implications for behavior are not well known. Well, we have a new preprint for that! 1/4

    Very happy to have this out! Dopamine transients produce learning about antecedent cues, without making those cues valuable. Thread below summarizes our key points👇 Particularly proud as I spent experiment 3🤮 in a bin between squads while pregnant 😂
