Re: EMG from Hand Muscles

Hello! I'm having similar problems to the users above. I'm collecting GSR and my pair of flat CMS/DRL electrodes doesn't seem to connect properly (the blue light is blinking) when applied to the back of the hand, the arm or the forehead. I've tried massaging some gel into the skin beforehand, but it...

I have the passive flat GSR electrodes but what I'm asking about are the CMS/DRL electrodes, which the GSR manual indicates should be placed on the back of the hand.

Hello, I'm new to Biosemi and I'm trying to figure out how to record just GSR for my experiment. I have a few questions: 1. Where should I place the CMS/DRL electrodes? On the ActiveTwo GSR manual it sais to place them on the back of the hand (see http://www.hum.uu.nl/uilots/lab/resources/GSR.PDF). ...
