Understanding the Default Mode Network (DMN) and Its Role in Depression
When analyzing the brain’s large-scale networks, researchers have identified a compelling connection between the Default Mode Network (DMN) and depression. But what exactly is the DMN, and how does it contribute to depressive mental health conditions?
By exploring how this network influences mood, cognitive function, and decision-making, we may better understand how to treat treatment-resistant depression—including emerging therapies like Ketamine-assisted treatment.
What is the Default Mode Network (DMN)?
The Default Mode Network is a collection of interconnected brain regions that activates during rest or introspective states. It is especially active when we’re:
- Daydreaming
- Recalling memories
- Engaging in moral reasoning
- Processing social concepts
- Thinking about ourselves
Unlike the task-positive network, which becomes active during goal-directed activities, the DMN becomes more engaged when the mind is not focused on external tasks.
How Is the DMN Linked to Depression?
Studies have shown that individuals with major depressive disorder (MDD) often experience heightened activity in the DMN. This overactivity is strongly associated with rumination, which the American Psychological Association defines as:
“A recurrent, self-reflective, and uncontrollable focus on depressed mood and its causes and consequences.”
Rumination isn’t just overthinking—it’s a core feature of clinical depression and anxiety disorders. Research indicates that excessive DMN activity contributes to negative self-referential thought patterns, leading to deeper depressive episodes.

What Is an Overactive Default Mode Network?
An overactive DMN results in an ongoing loop of negative thoughts, making it difficult for individuals to shift their attention away from distressing emotions or self-criticism.
Even mentally healthy individuals can experience occasional rumination, but chronic DMN overactivation is more common in those suffering from:
- Major depression
- Anxiety disorders
- PTSD
- Chronic pain syndromes
Reducing DMN activity has been linked to lower levels of rumination, offering a direct path toward relief from depressive symptoms.
How Psychedelic Treatment Affects the DMN
One of the most promising new interventions for depression involves psychedelic-assisted therapy, including the use of Ketamine.
Ketamine is a NMDA receptor antagonist and AMPA receptor stimulator that has shown profound results in disrupting maladaptive brain activity patterns, including DMN overactivation.
Recent clinical studies have shown that Ketamine therapy can:
- Reduce DMN hyperconnectivity
- Interrupt cycles of rumination
- Improve mood within hours
- Help patients unhook from negative thought loops
