Abstract
System and methods consistent with the present invention decode brain signals. The system includes a receiver for receiving an input signal representing multiple individual neuron signals, and a frequency filter for separating the multiple neuron signals from the received input neural signal. A rectifier full wave rectifies the filtered neural signal and an integrator integrates the rectified neural signal to obtain an envelope of the rectified neural signal. As a result of this processing, sample values of the neural signal envelope represent neurological activity.
