Please read this comment regarding acceptable Cyton impedance ranges,

Thank you for your advice. We tried it, and it reduced our impedance to below 100 kohms.

* In the OpenBCI GUI impedance/N-status check, we typically see around ~5000 kΩ impedance per channel even after all the gel application.

Happy to request impedance test video before

I'm using dry electrodes. They definitely often have poor skin contact, but I already tested them on a person without any hair and had the same outcome at one point. Also, the impedance test is workin

All signals are railed, although the impedance test is confirming low resistivity.

I'm using the electrode gel cap with the Cyton Board and while I got good SNR on the first day of use, it has dropped significantly on subsequent days and I can't seem to recover it. After the first d

When analyzing data using EEGLab, I noticed increased amplitude and strong high frequencies in channels F3 and F4. I then checked the impedance values ​​of channels F3 and F4, which were normal, aroun

Are you still seeing expected impedances? In other words has the impedance degraded over time, since they were new?

* At what point should this be considered normal wear vs. electrode degradation affecting impedance and signal quality?

By Good Signal vs Noise metrics- I meant, is there any objective measure (like impedance) to confirm the contact quality so we can say “this channel contact/setup is OK and we are getting a good sign

The GUI / Cyton 'impedance widget' WILL NOT work with Thinkpulse, because that widget depends on the ADS1299 chip acting as current source on the passive (non active) electrode having direct skin cont

In the discussion above, we saw that Julien mentioned the impedance test should be correct with a x24 gain, but he didn't test it. We tested it with "no contact" with the head and it doesn't

To clarify on the impedance, Cyton WITHOUT Thinkpulse uses a current injection method to measure skin impedance. This cannot work through an active electrode. The impedance widget displayed impedances

Impedance: since impedance results may not be reliable, what’s the best way to verify

re: impedance. See this comment at link below by Julien, the Thinkpulse developer.

contact” case, the Open BCI GUI is showing low impedance, which is confusing to me. Because in the Open BCI documentation, it says otherwise. Attached the ss.

Despite correct placement and consistently excellent impedance values (typically 4–10 kΩ across channels), the EEG signal is almost always flagged as “Near Railed” or “Railed,” with rail percentages f

During impedance testing, the impedance values of certain leads remain around 3 or 4kΩ.
