Dr. Donnelly wears a headband with three electrodes attached on the inside. The electrodes connect with his forehead. A small transmitter box, in back of his head, sends neural signals to a receiver box that is connected to the modem port of the computer. The receiver inputs the signals to the computer through the modem port where they are input to the computer in real time to a software application that converts the signals into frequency and amplitude values.

On the computer monitor, you can see the brainwaves that are being input when this picture was taken.

Brainwave Music

Hannah is sending her brainwaves to the computer, and you can see her brainwave signals on the monitor
. Dr. Donnelly is making a documentary videotape of Hannah's experience.


Ryan is transmitting his brainwaves to the computer while Hannah videotapes him for the documentary video. Ryan's brainwaves are being output from the computer to a MIDI device that converts values of the brainwave signals to MIDI notes which are then input to a Roland keyboard.

Hannah's brainwaves are also being output through the midi translator box and input to the Roland keyboard. By doing this, Hannah, like Ryan is making brainwave music.
Samples of their brainwave music can be heard from the Brainwave Music link.


Ryan concentrates to focus his attention. As his focus increases, he relaxes, and the brainwaves begin to settle down. The more he relaxes, the more the frequencies lower and switch from beta to alpha and theta frequencies.
