Figure 2. Gamma Power and Suicidal Ideation and Depression.

Figure 2.

Images of normalized, root mean square gamma power (30–50 Hz) estimates associated with suicidal ideation (SI) and depression (MADRS – without SI) from the linear mixed-effects model are superimposed on a high-resolution structural scan. Images are thresholded at pFDR<0.05. A network of regions centered in the insular cortex showed associations with SI scores, while a more dorsal, distributed network of regions showed associations with MADRS (without SI) scores in our patients. In addition, within insular cortex, bilateral anterior regions showed significant associations with SI, while more dorsal, posterior (and left-lateralized) regions were associated with MADRS (without SI) scores.
