Figure 3

Median (thick lines) of wavelet phase coherence between (a) BP vs. SASLEFT, (b) BP vs. HbO2 and (c) SASLEFT vs. HbO2. (d–f) Phase differences for the coherence in (a–c). Coloured shading indicates the interquartile range (25th, 75th percentiles) for 30 subjects. Coherence below the 95th percentile of the surrogates (light grey line and shading) is not considered significant.
