Components were classified with ICLabel (version 1.7; Pion-Tonachini et al., 2019), and components with a probability above 0.9 for the Eye or Muscle class were reviewed visually and removed ([N] components). Data were then low-pass filtered (passband edge 30 Hz, cutoff frequency [33.64] Hz at −6 dB, filter length [59] points; pop_eegfiltnew, firfilt plugin 2.8).
