A female participant who scored the maximum on the Absorption Scale reported a spiritual experience—feeling she was meeting God—while immersed in a whole-body perceptual deprivation tank. Her experience included imagery of a spaceship, corridors, a man in white, speaking to God, the sun, supernova, concentric images, and an out-of-body experience. Her EEG showed frontal and parietal left-greater-than-right alpha asymmetry at baseline, and during the tank condition, a global increase in alpha power with a sharp increase in right-frontal alpha power. Comparing her data with another high-absorption participant and two low-absorption participants suggests that verbalizable spiritual experiences may be linked to increased right-frontal alpha power, whereas ineffable mystical experiences might involve increased left-frontal alpha power.

Silence-related experiences during meditation are linked to changes in brain structure and reduced attentional effort. In a study of Quadrato Motor Training (QMT), participants who reported increased silence-related experiences after six weeks of practice also showed decreased attentional effort and increased fractional anisotropy in the left uncinate fasciculus, a white-matter tract. The findings suggest that silence in meditation involves specific neuroanatomical changes and may reduce the cognitive effort required to maintain attention.

This editorial introduces a collection of research exploring the neurophysiology of silence from multiple perspectives, including neuroscience, psychology, education, and contemplative traditions. It argues that silence is not merely the absence of sound but an active state that can influence brain function, cognitive processes, and well-being. The editorial highlights how silence may promote mental clarity, stress reduction, and restorative states, with potential applications in learning and education. It sets the stage for examining how silence affects brain activity, cognitive benefits, and psychological health, suggesting that understanding these mechanisms could inform practices for enhancing mental clarity and knowledge acquisition.

Immersion in the OVO Whole-Body Perceptual Deprivation chamber, a homogeneous sensory environment, consistently produces positively connotated, bodily-oriented, and cognitively dedifferentiated subjective states in most people. Semi-structured interviews with 32 participants, analyzed by three independent evaluators, showed significant consensus on experiences such as softened boundaries across time and sensory modalities. These subjective findings align with prior electrophysiological results that reported increased delta and beta activity in the left inferior frontal cortex and left insula during immersion.

A hypothesis paper proposes the Sphere Model of Consciousness (SMC) to examine consciousness and self-awareness, aiming to address methodological issues in consciousness research. It presents a preliminary attempt to validate the SMC using a simplified electrophysiological topographic map of the Self, showing a gradual shift from faster to slower frequency bands that mirrors dynamics between SMC states of Self. A mini-review of studies explores whether different SMC states of Self correspond to specific frequency bands, and the theoretical argument suggests the SMC's hierarchical organization of three states of Self mirrors the hierarchy of Focused Attention, Open Monitoring, and Non-Dual meditation types. Testable predictions and potential applications are offered.
