Figure 3.

Individual examples of relative power spectra for each group visualised over the recording time. Note the consistent α-power elevation in the major depressive disorder (MDD) patients (a), CG25, patient 7; (b), bed nucleus of stria terminalis (BNST), patient 10. In obsessive compulsive disorder (OCD) patients the α-power peak was smaller and less consistent over time (c), BNST, patient 17. Time–frequency representations in the figure were interpolated for the purpose of visualisation. Colour bar indicates relative spectral power (a.u.).
