Spindle detection agreement between our CWT detector with fixed frequency ranges (slow spindle: 11–12.9 Hz, fast spindle: 13.1–16 Hz) compared to the same detector with individually adjusted spindle frequency ranges. Agreement was calculated from pooled channels Fp1A2, F3A2, C3A2, and P3A2. CWT, continuous wavelet transform; SWS, slow wave sleep.
