    Predictive Routing: "There are no special error-detection circuits or mechanisms." There are instead pathways that are gated by predictions and thus can be activated by unexpected inputs. Amazing monkey electrophysiology work by Andre Bastos

    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!

    My blogpost on how & why we use convolutional neural networks as a model of the visual system is probably the most read thing I've ever written and it's now been expanded & updated into a proper review article, complete with 136 references & 5 new figures!

    I am very excited, to finally share this: Using a functional approach we uncovered a mechanism for whitening, a fundamental computation that decorrelates neuronal population activity for pattern classification by memory networks.

    Thanks to for creating really easy-to-use code for assessing gender balance in your own reference list based on the work from "The extent and drivers of gender imbalance in neuroscience reference lists" .

    New from "Efficient Coding in the Economics of Human Brain Connectomics" Here we develop a model to understand how network structure and metabolic resources support and constrain the efficient transmission of information.

    For a long time, I thought I had to choose between art and science. My time in grad school has taught me there is SO much overlap! I also learned that I thrive at the intersection; doing both balances me out.

    New prepint! We found that similar memories repel away from one another over learning such that they are remembered as further apart than they were experienced. These distortions were associated with reduced interference suggesting an adaptive mechanism.

    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 😂

    We developed a new standard space to compare levels of brain organisation. It stems from a multi-modal cortical wiring scheme, which neatly links local cytoarchitecture to global functional dynamics. The structural manifold preprint and code are out now!

    Out today, "Ventromedial prefrontal cortex compression during concept learning" w . vmPFC compresses information during learning in a goal-directed manner. Its timecourse is unique and parallels attention weights from learning models.

    1/ Hippocampal-prefrontal awake replay paper in the new issue. CA1 reverse replay for retrospection, forward replay for prospection, with opposing learning gradients. CA1-PFC replay supports past recall and future planning for spatial working memory.
