With ThoughtStream, we've introduced the world's first personal galvanic skin response (GSR) biofeedback training system: accurate as many clinical models, yet extremely easy to use.

We designed ThoughtStream to travel: lightweight, attractive, with an unique palm-of-the-hand sensor. We include an attractive carrying case, headphones and a manual - everything you need to get started!

If you are serious about exploring the advantages of biofeedback, a Windows 98+ computer program is available at no charge.

ThoughtStream features:

Unique four-color visual display shows you exactly how you are doing
Eight sensitivity levels for beginning to advanced training
Exceptionally smooth audio feedback
PC interface option
Can interface with and control the MindLab Pro system
New! Mental Games multimedia software package now available

The WaveRider Pro has one dedicated channel for reading GSR and four multi-purpose low noise channels for reading signals from the brain, heart and muscles. A more sophisticated Biofeedback monitor.
