In neuroscience, the default mode network (DMN), also known as the default network, default state network, or anatomically the medial frontoparietal network (M-FPN), is a large-scale brain network primarily composed of the dorsal medial prefrontal cortex, posterior cingulate cortex, precuneus and angular gyrus.
The default mode network (DMN) is a network of brain regions that are active when an individual is awake and at rest. [25] The default mode network is an interconnected and anatomically defined brain system that preferentially activates when individuals focus on internal tasks such as daydreaming, envisioning the future, retrieving memories ...

A failure of the DMN to deactivate at proper times is associated with poor cognitive function, thereby indicating its importance in attention. [4] In addition to the default mode network, the posterior cingulate cortex is also involved in the dorsal attention network (a top-down control of visual attention and eye movement) and the ...
The default mode network (DMN) is thought to process and represent abstract social information, such as mental states, traits, and intentions. [3] [32] [33] Social cognitive functions such as theory of mind, mentalizing, emotion recognition, empathy, moral cognition, and social working memory consistently recruit DMN regions in human ...
Recent studies have used fMRI to explore specific brain networks, such as the salience network and default mode network, to understand their roles in schizophrenia-related symptoms. Alterations in these networks may affect self-referential thoughts and responses to external stimuli, potentially contributing to symptoms like hallucinations and ...
The salience network is theorised to mediate switching between the default mode network and frontoparietal network (central executive network). [1] [2] [3]The frontoparietal network (FPN), generally also known as the central executive network (CEN) or, more specifically, the lateral frontoparietal network (L-FPN) (see Nomenclature), is a large-scale brain network primarily composed of the ...
One study on personality and network neuroscience selected regions-of-interest based on their inclusion within the default mode network (DMN), the salience network (SN), the cognitive executive network (CEN), or on their strong relation with these networks to investigate the relationship between personality domains and brain activity.
