1974-present Pairs of participants sit side-by-side before a monitor, each wired with EEG sensors to the scalp. On the monitor they see the real-time image which reflects the correlated output of their brainwave activity after it has passed through a computer (originally the PDP 11, most recently the Macintosh.) This image is superimposed on their video image (a camera sits atop the monitor.) Through extensive public participation, Sob ell was able to prove that participants are able to influence one another's brainwaves nonverbally.
Sobell has installed the piece for public participation at Sepulveda VA Neuropsychology Lab, Los Angeles; Houston's Museum of Contemporary Art; and Long Beach Museum of Art.
