[HTML][HTML] Pseudo-linear Summation explains Neural Geometry of Multi-finger Movements in Human Premotor Cortex
How does the motor cortex combine simple movements (such as single finger
flexion/extension) into complex movements (such hand gestures or playing piano)? Motor …

Hierarchy between forelimb premotor and primary motor cortices and its manifestation in their firing patterns
Though hierarchy is commonly invoked in descriptions of motor cortical function, its
presence and manifestation in firing patterns remain poorly resolved. Here we use …

Bilateral population activity in the motor cortex and its role in upper limb control
TC Dixon - 2021 - escholarship.org
A canonical understanding of how the brain controls arm movements assumes that each
hemisphere delivers commands exclusively to the contralateral limb. This has been …
