Figure 3: Simulated ECoG experimental setup. Experimenter-controlled mouse position on the simulation computer modulates the high-gamma power of simulated directionally tuned ECoG signals. These signals are output at 2400 Hz using a National Instruments D/A card and are read into the Craniux system using the g.USBamp amplification system and BCI2000. The Craniux system then decodes the desired cursor position from the simulated signals using the population vector algorithm.
