Default mode network
Neural network active during rest and mind-wandering
The default mode network (DMN) is a network of interacting brain regions that is active when a person is not focused on the outside world. It is most active during rest, daydreaming, and mind-wandering. The DMN is thought to be involved in self-referential thought processes, such as reflecting on one's own emotions and memories.
Structure[edit | edit source]
The default mode network primarily includes the medial prefrontal cortex, posterior cingulate cortex, precuneus, and the angular gyrus. These regions are connected by white matter tracts and communicate with each other to form a cohesive network.
Function[edit | edit source]
The DMN is believed to play a role in various cognitive functions, including:
Clinical significance[edit | edit source]
Alterations in the default mode network have been associated with several neurological and psychiatric conditions, such as:
Research[edit | edit source]
Research on the DMN has utilized various neuroimaging techniques, including functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). These studies have helped to elucidate the role of the DMN in both healthy individuals and those with mental health disorders.
