An advanced meditative state called extended cessation (EC), where consciousness is voluntarily suspended and later resumes with heightened clarity and equanimity, provides a natural model for studying consciousness. Using ultra-high-resolution 7T fMRI with dense sampling of three individuals, the research mapped whole-brain activity, connectivity, gradients, and eigenmodes during EC, linking them to brain chemistry and cognitive maps. EC increased activity in sensory regions, reduced activity in higher-order association areas, subcortex, and brainstem, expanded the principal cortical gradient, and decreased low-order global eigenmodes.

Advanced meditators can enter a state called extended cessation (EC) in which they intentionally suppress consciousness and later emerge with clarity and equanimity. In the first electrophysiological study of EC, five meditators were recorded with EEG and MEG. EC markedly reduced alpha power and tended to increase neural complexity, unlike sleep, anesthesia, or disorders of consciousness. The findings indicate that the neural correlates of EC are distinct from other unconscious states and that complexity alone is not sufficient for consciousness, offering new insights into advanced meditation and human flourishing.

Extended cessation (EC) is a rare meditative state in which conscious experience temporarily stops, followed by heightened perception and emotional balance. In five highly trained meditators, electroencephalographic microstate analysis revealed that EC altered brain activity patterns linked to self-referential processing. Specifically, microstate B occurred less often and for shorter durations, while microstate C occurred more often and for longer durations. Transition probabilities also shifted, with more transitions from A and B to C and fewer from A to B. These changes appeared across delta, theta, and beta frequency bands, with additional band-specific effects for microstates A and D. The findings suggest EC involves a reweighting of self-referential and sensory processes.
