In terms of the photo you gave, what is the source? I see that there are alternating patterns with 8 channels relatively 'RAILED' in magnitude or no/bad electrode connections. And the other groups of

When we record EEG signals from a person, the electrodes placed on the forehead often become "railed,". Despite adjusting the electrodes to ensure they make proper contact with the skin, th

connecting the electrodes, some of them are not railed. Also, I checked the impedance, and most of them are between 10 and kOhm.

Also, I dropped 3 channels since the stream data through GUI is not railed and does not have a good signal-to-noise ratio.

Which is not railed but also doesn't look like signal (?)

Recently I have bought the OPenbci ALL-IN-ONE ACTIVE EEG ELECTRODE BUNDLE. When _ connected the 16 channels and started to test the kit, almost all the channels were railed 100%.

See this thread on suggestions for getting 'unrailed'.

I notice that even when the channel starts climbing to get railed the uVrms (if that's the same thing we're talking about) still remains well bellow 100, but since the channel eventually gets railed i

Why do channels get "railed" in the first place? understanding this might help me know how to get the setup I want to work:

Today I tried moistening my earlobes and pressing on the ear clips. This two actions returned the Railed to its normal values, on channel 10 I can even see myself blinking hard, but the noise is still

I have a problem. When I launch the Ultracortex helmet with Cyton and Daisy, all channels begin to show the same large noisy signal, at which the Railed is about 60-80%. The helmet worked fine before.

The recording files use microvolts. Did the EEG Time Series on the screen during recording appear to be 'railed' or not? The recording file is RAW with no pre-filtering.

I'm unsure what the unit used here is (?) -- I assume uv? If so it does indeed seem like everything I have is railed, but this doesn't match with what the GUI is telling me

During a session, the cyton board/wifi shield seemed to crash after getting railed, and since then we have not been able to reestablish a connection with it or the board. The wifi shield will still sh

as you can see from the picture, channel 5 EEG which is snap electrode gets immediately near railed and climbing, eventually completely railed if will stay long enough I take it from my last trails.

When I set it up my EEG golden electrodes get “Railed” as in the picture, and stop receiving a signal.

Did you try the link I gave for reducing 'railed' condition? OR switching off the railing channels?

Due to the nature of dry electrodes and me being a suboptimal eeg-on-head placer I expect a bunch of the electrodes will end up railed and most (all?) of them will be very noisy.
