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.

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.
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.
their brainwave music can be heard from the Brainwave Music
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.
