ABSTRACT:
A neurofeedback technique uses color as its feedback cue. A preferred embodiment of the invention includes an amplifier that receives EEG signals from electrodes (e.g., adhesive electrodes, SQUID sensors, etc.) on or adjacent the person's scalp, a low or band pass filter, a color processor and a display. The color processor converts an aspect of one or more channels of the person's EEG signal(s) to a color and shows that color to the person on the display. The aspect of the EEG that is converted to color can be the frequency or the amplitude of the person's EEG signal(s). If EEG amplitude is used in the conversion process, the instantaneous, average or peak amplitude can be used. This process is dynamic, meaning that the system repeatedly converts the EEG signal to color. Conventional adhesive electrodes or non-adhesive sensors can be used to detect the person's brain activity.
