Details
- scope
- Motor cortex population recordings with focal microlesions
- claim_text
- Encoding patterns underlying low-dimensional motor-cortex states are not strictly stable: they exhibit fast switching and slow drift, with slow drift specifically linked to behavioral performance decrements.

- While changes in fast switch rates were not necessarily associated with behavioral deficits, a significant increase in slow drift was accompanied by a decrease in behavioral performance.
