Inclusion Criteria: * Between the ages of 18-45 years old * Right-handed. * Covid has been found to have neurological effects in some people, but mostly the effects on sensorimotor control and neurophysiology are unknown.

Exclusion Criteria: * Past or present history of seizure, stroke, any brain or peripheral nerve disease, severe head trauma, or spinal cord surgery. * Learning or attention conditions such as ADHD. * Orthopedic or pain conditions, or a history of seriously injured bones, joints or muscles in either arm. * Lack of normal or corrected-to-normal vision.
