    Check out our new work with , , and ! We show that hippocampal place cells remap in similar + predictable ways across rats. This challenges the standard view that place cell remapping is random. 🐀🧠🗺️ Preprint here:

    New preprint out with and Ale Smidts in which we investigate the neurocognitive mechanisms underlying cheating behavior. We find that cognitive control is not needed to be honest or dishonest per se, but that it depends on an individual’s moral default

    Modulation of plasticity: Place cell reorganization by input from locus coeruleus (LC) to hippocampus (CA1). Activation of LC-CA1 axons near the reward induces place cell overrepresentation, inhibition of them suppresses it. Kaufman, Geiller & Losonczy

    New preprint with and ! arXiv: code: (thread) 1. Many models (e.g., in psych and comp neuro) don't have a log-likelihood in closed form, but we can easily sample observations from the model.
