OCD
demonstrated the alterations of PSD which reflects neural activity in TAF task and resting-state.
These PSDs are correlated to psychological measures. Therefore,
alterations of PSD in SN during TAF task seem to be associated with OCD
symptoms.
Power spectra under TAF task and resting state of OCD (red) and HC
(black). During resting state, intrinsic neural activity power within DMN had
significant difference at Bin1 and Bin2. Salience network showed significant
difference at Bin1 and Bin3 during TAF task. (Bin1: 0-0.05 Hz, Bin2: 0.05-0.1
Hz, Bin3: 0.1-0.15 Hz, Bin4: 0.15-0.2 Hz, Bin5: 0.2-0.25Hz)
Independent components of each group under the TAF
task. Spatial maps were thresholded at p < 0.05 using one sample t-test,
corrected for family wise error (FWE). (a) Default Mode Network (DMN), (b)
Central Executive Network (CEN), and (c) Salience Network (SN).
