Study Investigators






Goal: We aim to quantify motor cortical dynamics associated with static and dynamic grasping behaviors. Further, we will characterize the impact of somatosensory feedback on motor cortical dynamics and cortico-cortical sensorimotor communication.   

M1-S1 Responses and Communication










Study population and setting:

  • Participants include individuals with upper limb paralysis who have an intracortical sensorimotor brain-computer interface implanted as part of clinical trial 
  • Study is conducted under an FDA Investigational Device Exemption
