when we gain a new skill or we get more proficient at a skill so faster more accurate there tends to be more net excitation of the cerebellum to motor cortex communication and that is accomplished by reducing inhibition
The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
the cerebellum communicates with the primary motor cortex and it can do so through what's called inhibition and it has outputs that inhibit the activity of neurons in the motor cortex and elsewhere and that has a profound influence on the execution of motor Behavior and the learning of particular motor behaviors
