Figure 4.

Amygdala-associated functional brain networks. A: the resting condition (REST); B: the post-sham condition (SHAM); C: the post-acupuncture condition (ACUP). The functional connectivity maps on the left show the statistical significance level of the correlation (t > 5.8, df = 16, P < 0.01 FDR corrected) in a coronal brain section through the amygdala. The amygdala-associated networks on the right show the strength of a functional connection (the weighted and normalized correlations) between the left amygdala and other selected brain regions. Dotted lines indicate statistically insignificant correlations. For abbreviations refer to Table 1.
