Figure 6

First row represents group averaged time–frequency maps of inter-trial phase coherence (ITPC) with and without spindle presence during NREM sleep (electrode FCz). Values are Rayleigh Z-corrected to account for unequal number of trials. The second row illustrates z-scored wavelet amplitude values and illustrates a clear increase of spindle activity in the spindle condition relative to the whole NREM recording. Warm colors represent higher values and therefore stronger phase locking or amplitude increase.
