Investigation on the Cortical Communication (CortiCom) System

This trial aims to evaluate a specific BCI model, the CortiCom system. To learn more about the CortiCom Study, email [email protected] or call 410-955-6772.


  • The CortiCom Study will involve:
    • Surgery to implant an electrode grid to control the BCI
    • Training to operate the BCI three days a week at The Johns Hopkins Hospital
  • Participants will receive up to $3,000 in compensation.
  • The study will last six months.

The Cortical Communication (CortiCom) System's electrical grid connects to the rest of the computer system and its software.
