Weird 60Hz burst on some Ultracortex electrodes only
Hi, maybe some of you with more experience could help me identify the source of this strange artifact that appears from time to time (office settings)
In particular, I am looking for a explanation as to why the frontal electrodes seem to be almost unnaffected whereas the occipital ones are always the noisiest, not matter how much I readjust the Ultracortex on my head. Any leads? could it It be a huge equipment turning on? but why some electrodes only?
Thanks!
Thanks!

@wjcroft thank you so much for providing a reference. I think less than 5kohms is achievable but it takes a lot of fiddling around, especially for the occipital electrodes.
My current office development environment is indeed high interference, but there is little we can do about that right now. In particular, I have found another kind of noise, this time translating into actual jumbling of the packet order as recorded by the latest GUI v4.1.2. Here is an excerpt from a recent data acquisition:
I will try running tests in a cleaner environment, should I keep you updated on this thread or on a github issue? Also, would the move to the WiFi shield eliminate this kind of problem?
thanks
