    I'm happy to share that my paper is finally out, showing that the effect of TMS in brain activity depends on the connectivity profile of the target region and proposing an imaging marker to predict its effect

    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

    There are (at least) two ways to reduce fear memories: - extinction (stim no longer signals punishment) - overexpectation (stim A = fear, B = fear, but learn A+B is not EVEN WORSE) overexpectation uses OFC, extinction uses IL

    Off to a great start in 2020 with our latest paper showing that LC-NE modulates amygdala activity and drives stress-induced extinction deficits. Congrats to and twitterless Tom on this oustanding work!

    Awesome to have this collaborative effort from the out, with , in . In it, we asked if the PE exhibited by DA at cue onset is just an error, or if it also carries the upcoming prediction. 1/n Thread below 👇

    Varying the timing of manipulations in a Pavlovian task reveals a temporally restricted role of neurons primarily in reinforcing stimulus–reward associations, and less related to directly generating movements

    Got a new paper out in (w/ ) showing that algorithmically optimizing associative learning experiments may substantially increase inference accuracy. Similar approach could be used in other learning/decision making exp. paradigms.

    We have a new paper in ! In it, we show that the prediction error does NOT function as a model-free cached-value signal. Read on for a brief summary of our key points.

    Magnum opus by @CarlesRaver in . A pathway by which central nucleus of amygdala inhibits the parabrachial nucleus, thereby regulating pain perception. This amygdalo-parabrachial pathway is also causally involved in chronic pain.
