Mapping Electrodes to the skull

squadus

Out of curiosity, is it possible to map electrodes to the skull as opposed to using a cap?

I'm not sure what you are saying, can you elaborate? You can always use cup or other electrodes applied in the 10-20 map, or other maps.

In addition the the videos in that thread, there are others on Youtube showing how to measure 10-20 on the head with a tape measure.
