How does meditation affect default mode network?
Sources:
Meditation can significantly influence the default mode network (DMN), which is a collection of brain areas active when we're not focused on a specific task, often associated with mind wandering and self-referential thoughts. Engaging in meditation practices, especially those focusing on interoceptive (inner body) or exteroceptive (external environment) awareness, can help shift the activity within this network, reducing its engagement and potentially enhancing neuroplasticity. explains that opting for meditative practices that counter your natural awareness bias can make meditation more effective for altering brain states and improving mental focus 1 2.
Furthermore, both meditation and techniques like yoga nidra have been shown to suppress activity in the default mode network, promoting a shift away from habitual mind wandering towards more present and focused states. This reduction in DMN activity can lead to improved mood, better management of anxiety, and overall increased happiness, as continuously engaging the DMN correlates with less happiness 3 4.
RELATED QUESTIONSWhat are the functions of the DMN?
Sources:
The Default Mode Network (DMN) is predominantly active when we're not focused on specific tasks. It plays several key roles, including:
-
Mind Wandering: The DMN is engaged during mind wandering, spontaneous imagination, and daydreaming, as well as when our thoughts drift between the past, present, and future 1 2.
-
Self-Referential Thoughts: It is involved in self-reflection and self-referential thoughts, essentially when we think about ourselves or our life stories 3 4.
-
Imagination and Creativity: The network is crucial for imagination and creative processes. It becomes active when we close our eyes and reflect inwardly, drawing from memory and past experiences to create new ideas or concepts 4.
-
Incompatibility with Task Engagement: When we're engaged in specific tasks or focused externally, the DMN's activity is suppressed to allow other brain networks to take over. This switch optimizes performance and focus 2 3.
-
Emotional and Narrative Processing: It supports emotional and narrative construction in our minds, playing a role in forming narratives and understanding complex emotions and relationships 2.
In individuals with ADHD, the DMN may remain overly active during tasks that require focus, contributing to distracted thoughts and difficulty maintaining attention 5.
RELATED QUESTIONS-
Which brain networks are active in meditation?
Sources:
During meditation, several brain networks are activated, each playing a role in the meditative process. Key networks include:
-
Prefrontal Cortex: This area involves conscious thinking and self-control, helping to manage focus and intention during meditation. It is particularly active in meditative practices that involve concentration or attention control 1.
-
Anterior Cingulate Cortex (ACC): This region is associated with error detection, conflict monitoring, and emotional regulation. It's crucial for maintaining attention and managing distractions during meditation 2.
-
Insula: Engaged in both interoceptive and exteroceptive awareness, the insula helps in understanding bodily sensations, an integral part of meditation focused on awareness of breathing or body scans 2.
-
Default Mode Network (DMN): Typically active when the mind is at rest, the DMN is involved in self-referential thoughts and mind-wandering. During meditation, practices aim to down-regulate this network to increase focus on the present moment 3.
These networks work in concert to foster the state of mindfulness or focused attention characteristic of meditation, enhancing both emotional regulation and cognitive control. The specific activation patterns depend on the type of meditation being practiced, such as mindfulness, concentration, or movement-based practices 2 1.

What is meditation?
Sources:
Meditation is essentially a perceptual exercise that involves a deliberate shift in focus or awareness, aimed at reducing distractions and increasing mindfulness. explains that meditation isn't about adding more to your life, but about reducing distractions and becoming more aware of consciousness. The focus could be internal (on thoughts and bodily sensations) or external (on objects or sounds outside the body) 1 2.
Meditation practices vary greatly. They can involve focusing on specific points, such as a spot behind the forehead, or practicing open monitoring, where one deliberately does not focus on a single point. This practice helps in better understanding one's unconscious processing, allowing for more intentional and less reactive responses to life's stimuli 1 3.
Moreover, consistency in meditation, even for brief periods like 5 to 13 minutes daily, can enhance focus, mood, and cognitive performance by training the brain's focus and refocusing circuits 2. Overall, meditation helps in achieving a state of non-distraction and non-dual mindfulness, where the distinction between the actor and observer fades 1.
RELATED QUESTIONSWhat are some extroceptive meditation techniques?
Sources:
Extroceptive meditation techniques involve focusing on external sensory inputs rather than internal sensations or thoughts. describes a few methods to practice extroceptive meditation:
-
Visual Focus: Choose a focal point outside yourself, such as a specific spot on a wall, a plant, or a point on the horizon. This technique involves maintaining visual focus on the chosen point, which may make the visual system fatigue slightly. You can blink and relax your expression as needed. The important aspect is the practice of refocusing whenever your attention drifts 1.
-
Breath and External Awareness: Focus on natural cyclic breathing patterns while also directing your attention outward. This involves dedicating some of your attention to breathing while maintaining awareness of external stimuli in your environment. This approach can help shift focus from internal to external when needed 2.
-
Progressive Shifts in Focus: Begin by focusing your perceptual awareness completely on your breathing (interoception), then gradually move your attention to external points at varying distances. You can start with something within an arm's reach, then focus on a location a few feet away, and eventually focus on something far in the distance, like the horizon. This method enhances your ability to adjust between interoceptive and extroceptive focus 3.
These techniques help train your focus and refocus skills, which are key to effective meditation practices, allowing you to adapt your attention dynamically between internal and external perceptions.

How is meditation different from hypnosis?
Sources:
Meditation and hypnosis are related but distinct practices with different objectives and methodologies. explains that hypnosis differs significantly from meditation, NSDR (Non-Sleep Deep Rest), and yoga nidra, even if there are some overlapping elements like focusing attention.
Here are the key differences:
-
Purpose:
- Meditation: Generally aims to cultivate relaxation, awareness, and focus. It is often used to manage anxiety, stress, and to improve overall well-being 1.
- Hypnosis: Specifically designed to address particular problems or to bring about specific changes, such as quitting smoking, treating insomnia, reducing pain, or managing anxiety. It is particularly effective in a clinical context where it can significantly enhance outcomes for targeted issues 1.
-
Methodology:
- Meditation: Involves various techniques, such as focusing on the breath or a particular object, to develop mindfulness and refocus attention when the mind wanders. It can lead to relaxation and increased awareness 1.
- Hypnosis: Involves a unique brain state characterized by high focus and deep relaxation. It often uses specific scripts or imagery to guide the individual into a trance-like state, making the mind more open to suggestions that align with the desired therapeutic outcomes 2.
-
Outcomes:
- Meditation: While it can help alleviate certain problems, meditation generally aims to enhance overall mental and emotional balance rather than targeting specific changes 1.
- Hypnosis: Is goal-directed and involves specific techniques to cause changes in neural circuits, improving focus, relaxation, and brain plasticity. It's known for its ability to directly tap into circuits for drastic improvements in targeted areas quickly 2.
Meditation is more about ongoing practice and awareness, while hypnosis is about achieving specific outcomes through structured sessions.
