A study in Psychiatry Research: Neuroimaging found structural differences in the precuneus, a brain region associated with memory and self-focus, in individuals who tend to ruminate, which is common in depression. The findings suggest that rumination may result from network-level interactions in the brain.
The default mode network (DMN) plays a critical role in human creativity and the generation of ideas, according to recent studies. Researchers are exploring how manipulating this network can influence creativity.
