Selective coupling and decoupling prepare distributed brain networks for skilled action

The paper shows that selective coupling and decoupling of neurons across brain networks prepare for skilled actions, with specific neural dynamics predicting action quality and performance.

Evolutionary expansion of the corticospinal system is linked to dexterity in Peromyscus mice

This study shows that forest mice have larger corticospinal tracts and greater dexterity compared to prairie mice, supporting the hypothesis that CSN number expansion enhances motor skills.

Motor cortical output for skilled forelimb movement is selectively distributed across projection neuron classes

The paper shows that different components of motor commands are distributed across two types of cortical projection neurons in mice.

Dynamics of the Cortico-Cerebellar Loop Fine-Tune Dexterous Movement

This study investigates the cortico-cerebellar loop in mice, showing that perturbing the pontine nuclei alters motor behavior and suggests the loop fine-tunes motor commands during skilled reaching.

Motor cortex is an input-driven dynamical system controlling dexterous movement

The paper investigates whether motor cortex activity during skilled movement is driven by local dynamics or external inputs, finding that external inputs are required throughout the movement.
