![]() ![]() GSR can detect this strong emotion by simply connecting two electrodes(two fingers in one hand). Strong emotion will stimulate your sympathetic nervous system, which causes sweat glands produce more sweat. These results have been interpreted in terms of an active superficial membrane having a relatively low charge. The Galvanic Skin Response Sensor (GSR - Sweating) allows you to measure the electrical conductance of the skin. Current densities beyond 11 μamp/cm2 produce an ‘injury’ effect manifested in GSR and apparent resistance. The effector is a poor rectifier, but there is a pronounced effect of polarity of current on the amplitude of the GSR in the case of large cations or anions combined with smaller ions of opposite charge. GSR and R are reduced by acids and alkalies and by detergents. GSR measures the change in electrical activity, which takes place due to the shift in sweat gland activity (as shown in Fig. Ca ++, increase GSR by several hundred per cent, while at the same time reducing basal resistance (R). 3.1.7 Galvanic skin response There is an increase in eccrine sweat gland activity when saddening, threatening, joyful, etc. ![]() K +, may reversibly reduce GSR amplitude and R by 40% larger cations, e.g. Comparison of inorganic chlorides shows that small cations, e.g. Several membrane-like properties of the effector in the galvanic skin response (GSR) have been measured in humans by comparison of activity at a control site with that of a site subjected to changes of external chemical environment or changes in direction or density of imposed current. ![]()
