Breathing, beyond its metabolic role, has been increasingly implicated in shaping perception, attention, and aspects of cognitive processing. Here, we propose the Rhythmic Embodied Perception (REP) Framework, a multi-level framework linking body and brain to explain how respiration structures conscious experience. At the neurophysiological level, slow respiratory cycles modulate cortical...

Identifying the neural correlates of consciousness (NCC) is widely regarded as imperative to our understanding of consciousness. Although several scientific theories of consciousness make predictions about the NCC, they often differ in their level of detail, making direct comparison through experimental findings difficult. Here, we report an adversarial collaboration protocol in which unbiased...

Hemispherotomy is a surgical intervention for severe drug-resistant epilepsy that fully disconnects the lesional brain hemisphere from the rest of the nervous system. This creates a rare opportunity to explore whether consciousness can be sustained without external input. The default-mode network, linked to introspective mental activity, is considered a necessary, though not sufficient,...
Dreams offer insight into how individual differences shape conscious experience in the absence of external input or task demands. This study examines whether synesthesia is linked to distinct patterns in dream content, suggesting underlying differences in cognitive architecture. Leveraging the statistical power of large-scale, naturalistic data, we analyzed 2,337 dream reports from Reddit,...
The degree of interaction between language and consciousness is a theoretically significant yet poorly understood question. In this review, we examine neuroimaging, cognitive, and neuropsychological studies that address this issue by distinguishing between different aspects or dimensions of language and consciousness. The reviewed studies indicate that high-level semantic and sentence...
Non-pharmacologically induced altered states of consciousness that promote mental health and wellbeing are a growing focus of clinical and basic research. Previous work has revealed the mood-augmenting, belief-altering, and self-transcendent effects of aesthetic-chills-inducing audiovisual stimulation. The current study investigated how a guided loving kindness meditation (LKM) combined with...
Mediumistic trance, studied as a cultural phenomenon, is considered an altered state of consciousness with dissociative and non-pathological characteristics. Studies on the effect of this trance state on linguistic performance using electroencephalography (EEG) are still scarce. We investigated the brain electrical activity of mediums using quantitative EEG (qEEG) during writing in waking and...
A growing number of advanced neuroimaging studies have been used to evaluate the nature of consciousness. Such studies have focused on various states of consciousness as well as ways of inducing altered states of consciousness. Various states of consciousness include the normal waking state, sleep states, the brain under anesthesia, and the impact of disorders such as seizures or schizophrenia....
A central challenge in consciousness research concerns the relationship between neural activity and conscious experience. While decades of work have identified numerous neural correlates of consciousness, these findings increasingly indicate that activation magnitude, localization, or stimulus processing alone are insufficient to account for awareness. What remains less clearly articulated is...
Contemplative practices encompass a range of mental and physical exercises that cultivate awareness, steadiness, and compassion. While contemplative practices have been shown to treat trauma, their application toward historical trauma is limited. To address this gap, our scoping review aims to answer the following research questions: (1) What contemplative practices have been applied toward...
