Default Mode Network
A network of brain regions in neuroscience that activates automatically when the brain is not engaged in external tasks. It is involved in self-referential thinking, memory recall, and prospection, and is closely associated with rumination and mind-wandering.
Timeline (last 90 days)
Resting-state fMRI studies show that even when performing no task, the brain has widespread connectivity such as the default mode network, and each region still has spontaneous activity.
Multiple studies have proposed that psychedelics may temporarily break fixed neural connectivity patterns by altering the activity of the brain's default mode network (DMN)
Psilocybin has been found to significantly reduce DMN connectivity strength within hours and promote the formation of temporary connections between brain regions that do not normally communicate
Patients with depression and PTSD often exhibit hyperactivation and rigidity of the DMN
The default mode network primarily includes regions such as the medial prefrontal cortex, posterior cingulate cortex, and precuneus
The rumination state is associated with overactivation of the default mode network.
During event updating, parts of the default mode network interact with the hippocampus, potentially transferring recently experienced events to long-term memory while clearing short-term memory.
The default mode network (DMN) is a set of brain regions that show increased activity when the brain is in a task-free state, primarily including the medial prefrontal cortex, posterior cingulate cortex, and inferior parietal lobule.
Long-term meditation practice has been observed to be associated with increased gray matter density in the prefrontal cortex and decreased activity in the default mode network.
When a person is in a state of overthinking, the Default Mode Network (DMN) is highly active, leading to rumination and escalating anxiety; when entering goal-directed action, the task-positive network is activated and DMN activity is suppressed.
