Study Description
Brief Summary:
The purpose of this research is to develop tools to help people who are paralyzed. These tools are called brain-computer interfaces (BCIs). BCIs would allow a person to use brain signals to operate technology. Specifically this project's goal is to design a BCI to operate a switch.

Condition or disease Intervention/treatment Phase
Healthy Device: Brain Computer Interface Switch Phase 1 Phase 2

Detailed Description:
The investigators want to make a BCI that can be used to operate commercially available technologies for communication, environmental control or computer access. The BCI would replace a switch to let people operate these technologies without moving. However, investigators need people to test the BCI so they can determine how effective it is in replacing a switch.

Arms and Interventions

Arm Intervention/treatment
Experimental: Pilot Testing Device: Brain Computer Interface Switch
Subjects will wear an EEG cap for 1-2 hours typical per session and use the brain computer interface to operate assistive technology. Subjects will be asked to participate in 14-20 sessions.

Outcome Measures

Primary Outcome Measures :
  1. Accuracy of Using the BCI as a Switch to Select From 4 Targets Using Scanning [ Time Frame: 8 sessions over 2 months ]
    Average accuracy for selecting one of 4 targets with a switch operated by a brain-computer interface controlled by power in the sensorimotor rhythms. The 8 sessions were conducted over a 2 month period. Accuracy was calculated as the percentage of trials in which the target was correctly selected. Trials for all sessions were combined to create the overall average. Therefore, there is no standard deviation. .
