The Prefrontal Cortex (PFC) is one of the principal brain regions studied in consciousness. Previous investigations suggest that the PFC is an important neural hub in both awareness and the manipulation of the content of consciousness. Despite a consensus in the scientific community regarding PFC function in cortico-cortical networks, there is still intense debate as to its role in the...

Exploration of human consciousness remains a final frontier within basic neuroscience; that is, how the finite biological structure and function of the brain give rise to the seemingly infinite expanse that encompasses the terrain of the mind. Contemporary mindfulness and other contemplative practices across historical and post-modern traditions involve systematic forms of mental training that...

The modern mindfulness movement rests largely on the twin pillars of scientific investigation and Buddhist philosophy of mind. However, in its current form and application, the scientific study of meditation is celebrated while the Buddhist roots of these practices and modes of investigation are often obscured. This paper highlights the utility and value of Buddhist ideas in the context of...

This study uses a combined categorical-dimensional approach to depict a hierarchical framework for consciousness similar to, and contiguous with, factorial models of cognition (cf., intelligence). On the basis of the longstanding definition of time consciousness, the analysis employs a dimension of temporal extension, in the same manner that psychology has temporally organised memory (i.e.,...

Both psychedelics and meditation exert profound modulatory effects on consciousness, perception and cognition, but their combined, possibly synergistic effects on neurobiology are unknown. Accordingly, we conducted a randomized, double-blind, placebo-controlled study with 38 participants following a single administration of the psychedelic psilocybin (315 μg/kg p.o.) during a 5-day mindfulness...

Characterizing consciousness, the inner subjective feeling that is present in every experience, is a hard problem in neuroscience, but has important clinical implications. A leading neuro-scientific approach to understanding consciousness is to measure the complex causal neural interactions in the brain. Elucidating the complex causal interplay between cortical neural interactions and the...

Purpose of reviewNear-death experiences (NDEs) are conscious perceptual experiences, including self-related emotional, spiritual, and mystical experiences, occurring in close encounters with death or in non-life-threatening situations. The origin of NDEs remains unknown. Here, we review recent advances in the understanding of NDE semiology and pathophysiology.Recent findingsRecent prospective...

We study the transition in the functional networks that characterize the human brains' conscious-state to an unconscious subliminal state of perception by using k-core percolation. We find that the most inner core (i.e., the most connected kernel) of the conscious-state functional network corresponds to areas which remain functionally active when the brain transitions from the conscious-state...
