Body-based monitoring of brain electrical activity
First Claim
1. A method for monitoring EEG electrical activity within the brain of a person having a body including a head, said method comprising:
- positioning a sensor at least proximate to portions of the skin of the body with the exception of the head to develop raw signals; and
filtering the raw signals to produce analysis signals including frequency components relevant to EEG brain electrical activity while attenuating unrelated frequency components.

Abstract
Apparatus and methods for monitoring electrical activity within the brain of a person (“brainwaves”) employing electrodes or other sensors connected or placed proximate to portions of the body below the head to develop raw signals. The raw signals are filtered to produce analysis signals including frequency components relevant to brain electrical activity while attenuating unrelated frequency components. Purposes include but are not limited to, biofeedback-based attention training, human performance training, gaming, and relaxation training. Either wired or wireless signal connections are made to electronic circuitry, typically including a digital computer, for performing signal processing and analysis functions.

6. A method for monitoring a mental state of a person having a body including a head, said method comprising:
-
positioning a sensor at least proximate to portions of the skin of the body with the exception of the head to develop raw signals; and processing the raw signals to produce at least one bandpass-filtered state-indicating signal representative of raw signal magnitude within a predetermined frequency range as an indication of the mental state of the person. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method for monitoring the level of attention of a person having a body including a head, said method comprising:
-
positioning a sensor at least proximate to portions of the skin of the body with the exception of the head to develop signals; and analyzing the signals to provide an indication of the person'"'"'s level of attention by isolating frequency components relevant to brain electrical activity indicative of the person'"'"'s level of attention while attenuating unrelated frequency components. - View Dependent Claims (13, 14)
