What Happens When Consciousness 'Disappears' — The Neuroscience of Nirodha Samapatti

In the world of meditation there is one ultimate state that has long been beyond the reach of science: Nirodha Samapatti, in which all perception, emotion, thought and the very sense of being oneself come to a complete standstill. Kouji Miki, a long-time practitioner of Vipassana and zazen, describes it as the death and rebirth of consciousness. Drawing on 7-Tesla fMRI, high-density EEG and Karl Friston's Free Energy Principle, this article explains the peculiar features of the state: no response to external stimuli, no sense of time and a rigid body, followed by overwhelming clarity on waking.

It then uses predictive processing and precision-weighting to ask why the brain creates consciousness and what a reset of it brings to thought, empathy and intuition. In an era when AI seeks to surpass human intelligence, it is also a practical inquiry into what human consciousness is and how we should live.
