SCP refers to Slow Cortical Potentials. The brain produces both AC signals (the kind we usually train using neurofeedback), which oscillate between positive and negative numerous times per minute. When you train a signal at 14 Hz, for example, it has 14 positive and 14 negative pulses each second, which we see on the screen as peaks and valleys above and below the baseline on the raw waveform. However, the brain also produces DC signals, which you might see when […]
