Study Details

Study Description

Brief Summary

Sensorimotor (also know as mu) rhythm based brain-computer interfaces (BCIs) are a tool for controlling electronic devices using only brain signals. Often, the computer software that analyzes mu-rhythm brain signals constantly adapts to the individual user's brain signals when the training target location is known. The investigators want the BCIs to be more universal, and not depend on knowing the target location. Therefore, the investigators will test the effect removing adaptation has on accuracy of using a mu-rhythm BCI.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Mu Rhythm with adaptation	Other: Brain computer Interface Mu (SMR) rhythm; 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 10 sessions.
Experimental: Mu Rhythm without adaptation	Other: Brain computer Interface Mu (SMR) rhythm; 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 10 sessions.

Outcome Measures

Primary Outcome Measures

1. Accuracy of a mu rhythm BCI using adaptation versus no adaptation. [10 times over 5 weeks]

   Accuracy with which subjects can select one of two targets after a 3-second time period. The accuracy for a run is calculated as the % of the trials in which the correct target is selected. The average accuracy will be calculated for each of the 10 usage sessions and changes over the sessions will be tracked.
