Cortical specificity matters: the importance of stimulating hindlimb representation for the recovery of skilled locomotion after severe spinal cord injury.

BACKGROUND The motor cortex exhibits a somatotopic organization that enables skilled control of lower limbs during locomotion. Following spinal cord injury (SCI), descending cortical commands are completely or partially disrupted, resulting in impaired volitional walking. We previously developed a closed-loop paradigm...

Distinct hindlimb motor cortex subregions encode forward and backward hindlimb movements in rats

The motor cortex is organized to coordinate voluntary movements through distinct subregions that control different parts of the body. Intracortical microstimulation (ICMS) with long-duration trains (LD-ICMS) can uncover complex, behaviorally relevant movement patterns that differ from the simple, joint-specific res...
