Figure 3. Correlations between MEG frontal alpha activity and PET glucose metabolism in healthy controls and in depression before and after successful rTMS treatment.

Figure 3

(A) In healthy subjects. Frontal alpha activity correlated well with glucose metabolism in the thalamus (circled in yellow). (B) Before rTMS. Frontal alpha activity correlated well with glucose metabolism in various parts of the prefrontal cortex, but did not correlate with thalamic activity. (C) After successful rTMS treatment. Frontal alpha activity correlated well with glucose metabolism in the thalamus (circled in yellow), brainstem, precuneus, and cingulate cortices. mPFC, medial prefrontal cortex; dACC, dorsal anterior cingulate cortex; MCC, middle cingulate cortex; SMA, supplementary motor area. Brain regions showing significant negative correlations (cluster-level corrected P<0.001) in each condition are shown in red color.
