Recording EEG + 8 external electrodes puts ergo signal to 0!
Posted: Mon Sep 08, 2014 10:35 am
Dear support,
I'm currently performing a combined EEG/EMG experiment (64 EEG channels + 8 externals). I'm also using Ergo1 and Ergo 2 channels to record response force signal.
Here is the problem:
When I plug the EEG into the amplifier, the response force signal (Ergo1 and 2) disappears. Note that signal is normal on the 64 EEG channels and the 8 externals. However, when the EEG is not plugged, the response force signal is normal. Any idea about the problem?
Cheers,
Mathieu
