Figure 2. From: Spontaneous brain activity relates to autonomic arousal.

Specific activation associated with the skin conductance response (SCR). The red color indicates voxels with positive relationships, while the green color indicates voxels with negative relationships.

Figure 5. From: Spontaneous brain activity relates to autonomic arousal.

Psychophysiological interaction analysis results. Regions in green indicate that the contribution of PCC to those regions is increased by SCR, or the response of those regions to SCR is increased due to the contribution of PCC. Regions in red indicate an enhanced anti-correlation between PCC and these regions by SCR.

Figure 4

Figure 4. From: Spontaneous brain activity relates to autonomic arousal.

The connectivity changes in default mode and other brain networks before and after regressing SCR out. The red color indicates voxels with decreased anti-correlated connectivity, while the green color indicates voxels with decreased positive connectivity with PCC after regressing out SCR.

Figure 3. From: Spontaneous brain activity relates to autonomic arousal.

Connectivity between PCC and other brain regions without regressed out SCR related brain activity. The green color indicates voxels with positive correlated connectivity of PCC, while the red color indicates voxels with anti-correlated connectivity. P < 0.001 and k > 120 resampled voxel size thresholds were used to plot this figure.

An example of skin conductance response (SCR) and PCC time courses from a single participant, along with frequency analysis of all subjects. (A) Raw unfiltered skin conductance signal showing the non-specific SCRs during rest from a single subject. (B) Band pass filtered signal showing SCR curves after detrending of A. (C) Average power spectral density of SCR signal for 15 subjects. (D) PCC time course from a single subject. (E) Band pass filtered and detrended PCC time course of D. (F). Average power spectral density of PCC signal for 15 subjects. (G) Averaged PCC-SCR coherence of 15 subjects.
