Examples of post-HI micro-scale ECoG spike transients (A, B) and non-spike ECoG background (C, D). The corresponding reverse biorthogonal wavelet transforms (rbio2.8) of the spikes (E, F) and non-spikes (G, H) at scale 7. The corresponding inverse Fourier transforms of the spikes (I, J) and non-spikes (K, L) using band-pass filter 80-120 Hz. The combination of these three time-series (to form a matrix of size 72×1×3) was used for training and validation of the WF-CNN classifier (M, N).
