What’s Going on In Your Brain’s Default Mode Network?

Do you feel like you have a wandering mind? Ever wonder what actually is going on in there? I loved this very informative video Why Meditate? Change Your Brain’s Default Mode to explain not only what is happening in our brains, but also what to do about it. Learn the power of redirecting while toning down the chatter and changing your default mode network.

  • A Note on Resting States, Resting Brains, and Meditative States

    A resting state, or ‘somatic rest’, would seem to correspond with a brain at rest or ‘neurologic’ rest, but by definition, somatic and neurologic rest are entirely different things. A resting ‘state’ or somatic rest represents the inactivity of the striatal musculature that results from the application of resting protocols (continual avoidance of perseverative thought represented by rumination, worry, and distraction.). Resting states also are affective states, as they elicit opioid activity in the brain. Resting states in turn may occur in tandem with all levels of non-perseverative thought that are passive or active, from just passively ‘being in the moment’ or being mindful, to actively engaging in complex and meaningful cognitive behavior. The latter cognitive behavior is also additionally affective in nature due to its elicitation of dopaminergic activity, and resulting opioid-dopamine interaction results in a perceived state of ‘bliss’ or ‘flow’. On the other hand, a resting ‘brain’, neurologic rest, or the so-called ‘default mode network’ is a specific type of neural processing that occurs when the mind is in a ‘passive’ state, or in other words, is presented with no or very limited cognitive demands. This results in ‘mind wandering’ that can entail non-perseverative (creative thought) or perseverative thought (rumination, worry). As such a resting brain may or may not correlate with somatic rest, and is correlated with a level of demand, not a kind of demand, as in somatic rest.
    Like the broad color palate that emerges from the intermix of three primary colors, it may be argued that meditative states are simply emergent properties of two very distinctive neuro-physiological resting states that have separate and easily definable causes. It is remarkable that in the literature of meditation, the neuro-physiology of rest both in body and mind is not defined, with a similar neglect to how neuro-muscular activity is actively shaped by experience or learning. The importance of meditation is very real, and the meditative community is understandably averse to equating it with rest since it makes meditation less ‘special’ or less marketable. But that is my argument nonetheless, which in the end provides a better advocacy of meditation by denying that meditation elicits a unique physiological process or state, which like the concept of ‘phlogiston’, or the imaginary element that enabled fire, impedes rather than furthers scientific inquiry.
