ElectricGuru is a computer program for neurofeedback. The current version of the program uses a fast Fourier transform to extract frequency bands from the raw signal. The band width can be set by the user as low as .125 Hz. Two independent code modules are incorporated internally to calculate FFTs so results can be verified by comparison. A simulator is built into the program to facilitate verification. Numerous graphs are displayed including a brain mirror. Magnitude and phase are both shown. The program plays a tone as a reward signal.
