Motor control refers to the process by which the nervous system coordinates the muscle and limbs to achieve a desired movement or set of actions. This includes the ability to anticipate, adjust and respond to deviations from the desired action.
A brain imaging study shows that humans with more complex cortical folds in a premotor brain region have a higher capacity to learn a challenging new motor skill during six weeks of practice.
Externally applied electrical stimulation over the cervical spinal cord improves arm and hand functions in people with chronic tetraplegia due to spinal cord injury.
Multilingual articulatory representations in the speech-motor cortex of a participant with vocal-tract and limb paralysis enabled the development of a bilingual speech neuroprosthesis.
Prosthetic embodiment, or the incorporation of a prosthesis into one’s sensory and functional body schema, may be achieved by engineering bionic limbs that leverage a closed-loop mechanoneural–machine interface. However, the subjective experience of embodiment remains difficult to define and assess.
The main direction of motor skill-specific information between rat primary motor cortex and dorsolateral striatum is shown to switch from cortex-predominant before learning to striatum-predominant after learning.
