Guest guest Posted July 24, 2012 Report Share Posted July 24, 2012 When the silver which is underneath the Silver-Chloride begins to show through (shiny spots), you have a bimetallic electrode and should replace it. The Silver/Silver-Chloride is dark, the silver is...well, silver. If you are using snap-in neurotrodes, I just wipe them off with a paper towel. If you have purchased cup electrodes, I dunk them in hot--not quite boiling--water three or four quick dunks, and the paste melts away and leaves them clean. You'll probably get a lot better signal if you use NuPrep or some other mildly abrasive prep and rub lightly for 8-12 seconds at each site before placing the electrodes. Alcohol may remove the oils on the skin, but it's not likely to clean off the dead skin cells, etc. Pete-- Van Deusenpvdtlc@...http://www.brain-trainer.com USA 678 224 5895BR 47 3346 6235The Learning Curve, Inc.

Guest guest Posted July 24, 2012 Report Share Posted July 24, 2012 One thing I didn't mention--with the neurotrodes, I actually get them get down to the silver as quickly as possible, then use them for a long time. It's when they are bi-metallic that they create a battery effect and actually make a signal from the electrodes themselves.

Guest guest Posted July 24, 2012 Report Share Posted July 24, 2012 Interesting. How long can you use them once they are completely down to the silver? Is there some type of cleaner that can be used to take the silver chloride off?

Guest guest Posted July 24, 2012 Report Share Posted July 24, 2012 I'm confused because you first said to replace them when the silver shows. Then you said they work best when worn down to the silver. Have I misunderstood? Thanks!
