Study Summary
The investigators will use fMRI to map movement activity in motor and somatosensory cortex using enriched imagery in people with chronic tetraplegia. The investigators expect that somatotopic organization of movement activity will be preserved in people with upper limb impairments, which can be quantified using the strength, area, and location of sensorimotor activity. Accurate mapping of the motor and somatosensory cortices using covert stimuli will help guide brain-computer interface (BCI) electrode design and placement. Moreover, these advanced mapping procedures will provide new insights into the functional interactions between sensory and motor areas of the brain after injury or disease.
Primary Outcome
Volume of peak activity strength in sensorimotor cortex for attempted movement of right thumb (D1).
