Communicating with electric fish

In the 1940’s Gray Walter discovered that when a person was subjected to a light flashing at a certain frequency, their brain wave activity would fall in sync with the flashing of the lights. Since then many devices have been developed to entrain brain waves. Most of these devices include small lights mounted in a pair of eye glasses. These lights flash at given frequencies and are controlled by a small computer in the base unit. Today, most Sound and Light Entrainment devices (SLEDs) also include a sound component. SLEDs are used by psychologists in their practices and by the general public for relaxation, stress management, insomnia, accelerated learning and retention, phobias, anxiety, fun, etc.

ElephantNoseFish.jpgENKI uses the bioelectric information from an Electric Fish to trigger human Brainwave Entrainment (or Brainwave synchronization). It generates sound and light pulses to induce a state of relaxation similar to the way traditional (SLEDs) work, but the electric communication signals comes from an electric fish rather than a chip.


The ENKI system is interfaced with the fish using sensors in an aquarium. You experience the electrical activity of the fish directly. The electrical fields are converted by ENKI into “binaural beats”, and light – experienced via Light frames – to stimulate Frequency Following Response.

With ENKI your own bio-electric field is connected to the aquarium allowing the electric fish to sense your presence (video).
