    Sad to hear of the passing of Richard Masland, a very generous, thoughtful and careful scientists, and also a good guy. He was a member of my thesis committee and a wise and caring mentor. Thanks for everything, Dick! Rest in peace!

    Happy to share this work! We built a model of a rodent, trained it to solve four tasks, and used methods common in neuroscience to study how the rodent controls its body. , Josh Merel, Yuval Tassa, Greg Wayne and

    Feynman's blackboard at the time of his death left us with the famous epigram: "what I cannot create, I do not understand” (also apparently: "know how to solve every problem that has been solved?!").

    The most important film you will watch this year. Devastating, uplifting, gut wrenching, and beautiful.

    NYT has been a mixed bag the last few years, but credit where credit is due. This is great reporting.

    A layman's write-up of our study, led by Ashesh Dhawale, on how the brain regulates motor variability, published in this week's Current Biology.

    Much is left to figure out about how these behaviors are learned and controlled, but I hope these studies will bring us a step closer to understanding how the mammalian brain learns new motor skills. Thanks for reading to the end!

    Steffen further showed that plasticity at excitatory synapses in DLS is essential for ‘storing’ the learned behaviors. Given that MC input to the striatum is dispensable, this suggests that plasticity happens at one of the other inputs to DLS, perhaps the thalamic ones. 29/n

    He silenced neurons in thalamus that project to the DLS in expert animals with well developed ‘dances’. Upon silencing, no more dancing. Animals reverted back to the species-typical lever pressing behaviors we see early in training and after DLS lesions. 28/n

    However, thalamic inputs to the DLS are comparable in strength and numbers to those from cortex. Steffen probed their function through the lens of the idiosyncratic behaviors we train. 27/n

    Let’s return to the question of how these ‘dances’ are generated. Remember that the DLS, which is an essential cog here, also receives input from the thalamus. If you didn’t know this, it may be because this connection is often omitted from textbook chapters on the BG.
