DSI – GRS
(Galvanic Skin Response )
The GSR (Galvanic Skin Response) sensor consists of dry electrodes with an electronic interface that allows it to plug into the auxiliary input channels of DSI-24 or DSI Flex system. It records electrodermal conductivity from the fingertips with included attachment straps.
GRS is the change in skin resistance due to emotional arousal.
DSI electrode types
Dry electrode wrist or finger-cuff
