Color-based neurofeedback
First Claim
1. A neurofeedback system, comprising:
- an amplifier that receives EEG signals from a person;
a color processor coupled to said amplifier; and
a display unit coupled to said color processor;
wherein said color processor dynamically converts an EEG signal from said amplifier to a color and shows the color on said display unit to a person being monitored;
wherein said display unit comprises first and second displays that are independently controlled by said color processor; and
wherein a predetermined color is provided on the first display simultaneously with the second display being provided with a color that is determined by said color processor based on the person'"'"'s EEG.

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.
