Study provides a new framework for investigating and formalizing the cognitive processes behind how humans use tools.
A prosthetic arm that is attached to the bone and controlled by electrodes implanted in nerves and muscles can operate more precisely than conventional prosthetic limbs. Researchers improved the neuroprosthetic hand by integrating tactile sensory feedback, so the patient can "feel" items.
Using robotics, researchers uncover mechanisms in the cerebellum and spinal cord that determine how the nervous system responds to induced changes in step length. The findings could have implications for physical rehabilitation programs for people with movement disorders.
