Mairi2 and Steves,
Do you have links or references for the actual re-numbering? I searched ASET and could not find anything.

I looked on-line but could not find anything. But the neurologist I sometimes work around mentioned it in passing and I was a little confused until I found it referred to in the 2nd edition of Sleep Medicine Pearls page 315.

I'll see if I can get something more specific.

So far all I could find with the electrodes labeled is on page 9 of this:

ftp://ftp.egi.com/pub/documentation/tec ... itions.pdf

Page 5 mentions the changes as being according to the American Electroencephalographic Society guideline.

Hope this helps.

I have asked my EEG dept and they did not hear of this. They also have still brand new still packaged XL-Tek EEG machines, and those head boxes are labelled the old way. So, I have no idea still.

probably places that are not performing higher density EEG's still use the older terminology. And I guess that would by and large be us in sleep medicine.

There are some schematics on this web page for both.

Hello everyone,
I wanted to ask you if there are any equivalents to the A1,A2 electrodes of the 10 20 system to the 256 electrode system?
Which electrodes form the 256 systems could I pick to match the A1,A2?
Thankyou very much in advance.

With so many sites (256) just picking the closest to M1, M2 should suffice for the generalized thing called sleep.
