The neuroscience of mindfulness: The Polyvagal Theory


How is it that we perceive threat and shift our attention to deal with it? Computers have been helpful in providing a metaphor for how our brain and nervous system work. This is consistent with how neuroscience conceptualizes the mind. For instance, Daniel Siegel, MD, author of The Developing Mind and The Mindful Brain, defines the mind as “an embodied and relational regulatory process.” See: conversation with Daniel Siegel.

However, there is a major difference with the computer: We are not neutral processors of information. Evolutionarily, the processing came as an ever increasing fine-tuning of our ability to respond to thread. This is very pragmatic, action oriented. We did not evolve to process scholarly report assessing the environment. We evolved to take action instantly. And emotions are a big driver.

So the processing of threat is mediated by the nervous system, especially the autonomic nervous system.

polyvagalWhen you took Science in school, the Autonomic Nervous System was probably described as having two branches: The Sympathetic nervous system, which gives us the energy for flight/flight. And the Parasympathetic system, mediated by the vagus nerve, which helps us slow down, and helps digestion and rest. In classical theory, these were the two forces balancing each other. It was assumed that the "window of mindfulness" was when the two were essentially balancing each other out.

More recently, neuroscientist Stephen Porges developed what he called the Polyvagal Theory, which identified a third circuit. The vagus nerve is divided into two parts, the ventral and dorsal:
- The dorsal part is the more primitive part of the nerve. It essentially does what, in the old mode, the Parasympathetic was described as doing.
- The ventral part is associated with mindful engagement.

So there is a specific circuit corresponding to mindful engagement. The following charts provide a visual model for Relational Mindfulness and the Autnomic Nervous System (ANS).

4 core ideas about mindfulness:

1. Mindful vs Mindless: Proactive Mindfulness Definition

2. To go from mindless to mindful, we shift attention

3. The neuroscience of mindfulness: The Polyvagal Theory

4. What relational mindfulness feels like: The emergent self
