(a), (b) Each channel represents the electrode position and
(c) represents PLV of each channel
Fig.3. Classification Performance
SLR input data as a minimum amplitude of LFP from 0 to 500
ms after the sound onset (a), average amplitude in 300ms in SS
(b), PLV of Non-Spindle LFP. 10-fold cross- validation (c).
