The small, hand-held and self contained GSR 2 is a Galvanic Skin Response monitoring device for home biofeedback. The GSR 2 precisely monitors your stress levels by translating tiny tension-related changes in skin pores into a rising or falling tone. Biofeedback is a training approach that helps you learn to develop greater control over your mind-body connection. It is used in hospitals and clinics, schools and homes to help individuals learn to relax when tapes, meditation, hypnosis and other approaches have not worked. Combine the power of you computer and the ease of use and sophistication of the GSR2 to provide many of the features of sophisticated biofeedback programs at a fraction of the cost.
