The Biology of
Centeredness

byDr. Ceren Akçelik BruniniNeuroscientist · Somatic practitioner · Co-founder of Dojo Bianco

A neuroscience-informed way of understanding motivation: not as willpower, but as something that grows out of how the body is organised in a given moment.

People who know what they need to do, yet cannot do it, are not failing morally or intellectually. They are living within the limits of a nervous system that is, for now, oriented toward survival rather than exploration. So the question changes: under what conditions in the body does meaningful engagement become available?

Ceren developed this framework from two directions at once: her doctoral research in neuroscience, and fourteen years of working with people through the body. It draws on polyvagal theory, research on interoception and emotion regulation, and predictive processing, in conversation with contemplative and martial traditions.

Three kinds of knowing

Each named for what it is.

Neuroscience investigates biological mechanisms through scientific methods. Psychology offers theoretical and empirical ways of understanding behaviour and experience. Contemplative and somatic traditions bring their own forms of observation and practice. They do not all prove one another.

The framework is offered as a working model and a research agenda, not a finished theory. Its proposals are meant to be tested.

Four motivational states

All four live in each of us.

All four exist in every person, and which one is present changes with time and situation. Each of us has one we lean toward, and use more often.

They are regions along a continuum, from protection toward coherent engagement, and movement goes both ways. Returning to a more protective state under stress is expected, and it is not failure.

The one you lean toward

If one feels most familiar, mark it. It is not a score, and not a place you have to stay.

Time

How does time feel today?

Each state seems to shape how we live with time: the past, the present and the future. Choose the sentence that sounds most like today.

Hara

Acting from center.

Across contemplative, somatic and martial traditions, hara (in Chinese, dantian) names a grounded, stable presence felt low in the belly, associated with clear action, good timing and emotional steadiness.

Here it is not a metaphysical claim. It is treated as a widely reported experience that may correspond to measurable conditions in the body: vagal regulation, clear interoception, and coordination between the prefrontal cortex and the limbic system. The belly is also a major hub of body–brain signalling through the gut–brain axis, which may be one reason the center is so often felt there.

Daily awareness practice

Three anchors.

Not to classify yourself, but to notice, with compassion, where you are.

Functioning is not the same as being well

Three ways to look fine.

It is possible to look functional while the body is still organised around threat. Real change shows as less effort for the same life, not only as more output.

  • Forced positivity. Performing calm or confidence while the body stays in threat.
  • Dissociative calm. Equanimity reached by disconnecting from the body rather than inhabiting it.
  • Willpower-driven function. Keeping going through sheer effort while regulation underneath stays strained.
An inner path

Awareness, Intention, Trust, Emergent Being.

Alongside the biology, the paper describes an inner process: becoming aware of the state you are in; setting intention as a gentle direction rather than a demand; trusting enough for protection to soften; and, when conditions allow, moments of aligned being. These phases repeat. We cycle through them again and again.

A heuristic model, not a diagnosis. The indicators on this page are meant to support reflection, to be read with compassion and attention to context.
