Foundations of Neurofeedback – Outline

Unlike the other components which all have a defined frequency range (e.g. 8.0-10.0 Hz for alpha), DC potentials are recorded with a low-frequency cutoff of 0.00000 Hz. That is, if the sensor is “sitting” at a steady offset of, say, 150 microvolts, then that signal can be recorded and trained. ................
