Fig. 2.

Comparison of microglial densities between the left and right anterior midcingulate cortex and between suicide (suic) and non-suicide (non-suic) individuals. a Significant difference in microglial density with a lateralization towards the right side is detected between the schizophrenia (Schiz) and the bipolar disorder BD individuals, not observed in the controls (contr). b Differences between non-suic and suic individuals are evident within the BD group; the BD non-suic subjects display a significantly lower microglial density compared to the suic victims. Comparing BD suic victims with controls, the difference is not significant. In the Schiz group, no significant difference emerges between suic and non-suic individuals regarding microglial density
