Disentangling Tinnitus Distress and Tinnitus Presence by Means of EEG Power Analysis
Figure 4
(a) Nonnormalized EEG spectral power adjacency matrix of Pearson product-moment correlations with tinnitus presence. Significance levels ( values) of the correlations are color-coded (one-sided, uncorrected for multiple comparisons). Electrodes on the -axis are aligned from rostral (top) to caudal (bottom), irrespective of laterality. Positions of electrodes on the central line are marked. (b)–(d) Topographic plots of EEG power correlations in the δ-band (0.5–4 Hz) (b), in the α-band (9–12 Hz) (c), and in the γ-band (30–40 Hz) (d) with tinnitus presence and strength of correlations (Pearson’s ) are color-coded.
