Mapping of Motor and Sensory Brain Activity Using fMRI
In Brief
A clinical study evaluating Motor or sensory imagery with fMRI for Functional Neuroimaging. Completed, enrolled 8 participants across 1 site.
Detailed 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.

Timeline
Interventions
Brain activity will be measured using fMRI while participants imagine different movements or sensations in order to assess the organization of sensorimotor cortical activity after injury
