Scientists Reveal Brain's Default Mode Network Structure

A study in Nature Neuroscience reveals the structural complexity of the brain's default mode network (DMN), showing it comprises diverse tissue types that support its role in various mental states, from introspection to decision-making, through distinct anatomical features and connectivity patterns. The research combines postmortem histology and in vivo imaging to map the microstructure and functional pathways of the DMN, highlighting its unique integrative role in human cognition.
