Two-dimensional Brain-Computer Interface (BCI) using hand imagery and tongue imagery. Imagined tongue movement makes the cursor move up (based upon activity in tongue motor cortex), and imagined hand movement makes the cursor move right (based upon activity in hand motor cortex). Lack of imagery makes the cursor move in the opposite direction. The brain shows power in the surface electrical potential between 77 and 85 Hz. For more information, see the manuscript: "Cortical activity during motor execution, motor imagery, and imagery-based online feedback" by Kai Miller, Gerwin Schalk, Eberhard Fetz, Marcel den Nijs, Jeffrey Ojemann, and Rajesh Rao, in Proceedings of the National Academy of the USA (PNAS), February 2010

  • Hi, is it ECOG or EGG your experiment is using?

  • I need to get your code to smooth activations on the cortex. I've just been using dots.
