    New preprint! We measured the complexity of model-based (MB) and model-free (MF) decision strategies using a novel adaptation of the information bottleneck. TLDR: human MF and MB strategies can be equally complex, and more MF does not = less flexible. Details in thread 1/18

    New in eLife: We characterized the function of the extensive projections from the auditory cortex to the inferior colliculus. Activating the projections directly, but not suppressing them or modulating cortical inhibition, affected collicular activity.

    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!

    Anyone who doubts that preprints are an amazing force for good should be swayed by this: the receptor for the Wuhan coronavirus is already identified and in the public domain thanks to h/t

    Check out our new preprint in which we find that Trump's tendency to repeat claims (whether true or false) increases the perceived truth of those claims, even for democrats!

    Cool work by ! “There was no correlation between how trustworthy someone’s face appeared and how much that person actually shared,” Dr. Lempert said. “It’s easy enough to recognize a face but hard to recall that additional information.”

    What makes a good lab? Are group meetings really the best way? In the we recently reexamined how we organize our weeks, and then redesigned everything in a systematic way (100% democratically!). I blogged about our design process and takeaways:

    Dr. Ma’s seminar at was awesome. He was amazingly insightful and candid about his path in academia, and gave great guidance and suggestions to help deal with a lot of the anxiety and worry we all feel in this career. Highly recommended!

    Processing of sounds in the auditory pathway is shaped not only by feedforward, but also feedback connections. By manipulating the projections from the auditory cortex to the inferior colliculus, we infer principles about the function of this feedback:
