1. A method for training a person to develop useful degrees of voluntary control of personal electroencephalographic (EEG) activity, said method comprising the steps of:
- (a) securing EEG leads to the person;
(b) receiving an EEG signal from the person;
(c) transmitting the resultant EEG signal to a filter;
(d) filtering the EEG signal; and
using a computing device;
(e) monitoring a predetermined EEG frequency band or subband;
(f) determining an EEG frequency value of a preselected aspect of said EEG signal; and
(g) generating a first audio signal at a first frequency that is delivered to said person'"'"'s first ear with minimal delay and generating a second audio signal that is delivered to said person'"'"'s second ear concurrently with said first audio signal, said second audio signal having a second frequency that differs from said first frequency by the value of said EEG frequency value;
wherein said preselected aspect is the frequency at which the peak energy of the EEG signal occurs.
