Dissociable cerebellar pathways for reach correction and learning
Neuron · By Courtney I. Dobrott, Abdulraheem Nashef, Matthew I. Becker & Abigail L. Person ·
The Brief
- Dobrott et al. tested the long-held idea that the cerebellum encodes movement corrections.
- In mouse reaches, the researchers identified spontaneous and induced errors.
- They found robust cerebellar output even when no overt corrections occurred; the source summary is truncated before the optogenetic results are described.
Why it matters
The study suggests cerebellar activity can be present without visible movement corrections, which bears on how the cerebellum contributes to motor control and learning.
Who’s affected
- neuroscientists studying motor control and cerebellar function
