Kudos to @science.org for this self-analysis of the peer review process. These kind of data are never shared and don't have to be. Wildly refreshing to see it out in the open. Editorial and peer review dynamics at elite general science journals | Science Advances www.science.org/doi/10.1126/...

If an action results in error, each neuron requires an individualized teaching signal that guides change in its output. This is the credit assignment problem of learning. Are there neurons in the brain that can compute such a sophisticated teaching signal? Yes. www.biorxiv.org/content/10.6...

Climbing fibers encode the gradient of a loss function for the cerebellum

Neurons in the brain are often many synapses away from motoneurons, yet if a movement results in error, each distant neuron needs a teacher that considers its specific contribution to production of th...

🧠 New preprint! How does the brain build specialized, efficient representations as we grow up? We used manifold learning to track the "intrinsic dimensionality" (ID) of brain activity in ~800 participants (aged 3mo–53yrs), as they performed naturalistic tasks and rested/slept.

New preprint w/ Leo Tiokhin & @lakens.bsky.social! Registered Reports (RRs) are great for science b/c publication is guaranteed before results are known, reducing publication bias & QRPs. This feature supposedly also makes them great for *scientists*. But is that really true? 1/ tinyurl.com/4sy993rr

Career incentives make Registered Reports unattractive under realistic academic conditions

Registered Reports are a publication format designed to reduce publication bias by guaranteeing publication before results are known. This guarantee is considered attractive in the prevailing ‘publish...

Today's #OA spotlight is extra special. Just this week, @mitpress.bsky.social published the 200th article in our OPEN ENCYCLOPEDIA OF COGNITIVE SCIENCE. Congrats to @mcxfrank.bsky.social & @asifamajid.bsky.social! We've come far since the 2023 @cogscisociety.bsky.social in Rotterdam! oecs.mit.edu

The cerebellum plays a role in motor learning and reinforcement learning. But does cerebellar learning generalize to all sorts of tasks? Here we test strong prediction: that cerebellar activity tracks passively learned sensory-sensory associations (statistical learning). See below for the answer!
