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.

Two timescales of drift observed; slow drift correlated with behavioral deficit

source_span
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.
study_system
Motor cortex population recordings with focal microlesions
section_title
14. Predictive-coding and dynamical-systems accounts — the role of recurrent excitatory feedback in error signalling, state estimation, and reservoir computing, evaluated against mouse data
evidence_summary
Population-state tracking in motor cortex over short trial blocks; causal perturbation by electrode-mediated focal injury.
