Table 2 Criteria for selection of EEG structures

From: Electroencephalographic profiles for differentiation of disorders of consciousness

  Frequency [Hz] Duration [s] Min. amplitude [μV]
Delta waves 0.2 – 4 >0.5 70
Sleep spindles 11 – 15 0.5-2.5 12
K-complexes* 0.05 – 2.5 0.3 - 1.5 100
Theta waves 4 – 8 > 1 15
Alpha waves 8 – 12 > 1.5 5
Beta waves 15 – 25 > 0.5 4
Spikes* 0.2 – 7 0.05 - 0.35 50
  1. Parameters of functions from MP decomposition, used for automatic detection of relevant waveforms. *For K-complexes an additional constraint on the phase, enforcing a negative deflection and condition for the amplitude to exceed also the background amplitude by factor 1.5, for spikes or the amplitude to exceed also the average background amplitude by factor 2.
