Abstract Self‐awareness, the ability to take oneself as the object of awareness, has been an enigma for our species, with different answers to this question being provided by religion, philosophy, and, more recently, science. The current review aims to discuss the neurocognitive mechanisms underlying self‐awareness. The multidimensional nature of self‐awareness will be explored, suggesting how...
Spontaneous brain activity exhibits a highly structured modular organization that varies across individuals and reconfigures over time. Although it has been proposed that brain organization is shaped by an economic trade-off between minimizing costs and facilitating efficient information transfer, it remains untested whether modular variability and its changes during unconscious conditions...

The sense of self is a foundational element of neurotypical human consciousness. We normally experience the world as embodied agents, with the unified sensation of our selfhood being nested in our body. Critically, the sense of self can be altered in psychiatric conditions such as psychosis and altered states of consciousness induced by psychedelic compounds. The similarity of phenomenological...

From archaic contexts to current reconfigurations, the shaman, wrapped in magical-religious lineages, operates as a guiding element, inducer of ecstatic states, and mediator between worlds. Can technology allow these attributes when digital codes and organic webs spin together, fueling cosmological dances and transitions to altered states of consciousness? The project Cosmic Dance, A...
Consciousness is one of final questions for humans to tackle in neuroscience. Due to a lack of understanding of basic brain networks and mechanisms of functions, our knowledge of consciousness mainly stays at a theoretical level. Recent studies using brain imaging in humans and modern neuroscience techniques in animal studies reveal the basic brain network for consciousness. The projection from...
ABSTRACT The cross-cultural practice of shamanism reflects an innate capacity for altered states of consciousness (ASC’s) that are elicited by stress, deliberately sought in shamanic rituals, and associated with psychopathology. Shamanic sickness, animal transformation, and death-rebirth experiences specifically resemble psychotic experiences. The triggers of shamanic and psychotic experiences...
Psychedelic substances induce profound alterations in consciousness. Careful preparation is therefore essential to limit adverse reactions, enhance therapeutic benefits, and maintain user safety. This paper describes the development of a self-directed, digital intervention for psychedelic preparation. Drawing on elements from the UK Medical Research Council (MRC) framework for developing...
Abstract Music and psychedelics have been intertwined throughout the existence of Homo sapiens , from the early shamanic rituals of the Americas and Africa to the modern use of psychedelic‐assisted therapy for a variety of mental health conditions. Across such settings, music has been highly prized for its ability to guide the psychedelic experience. Here, we examine the interplay between music...
Introduction During the last decade there has been a resurgence of interest on the use of psychedelics as novel treatments for mental disorders, including treatment-resistant depression (TRD). Psilocybin, the chemical component of “magic mushrooms”, has been administered with psychotherapy in randomized clinical trials (RCTs) showing large and sustained antidepressant effects. As the use of...

Consciousness can be defined as a phenomenological experience continuously evolving. Current research showed how conscious mental activity can be subdivided into a series of atomic brain states converging to a discrete spatiotemporal pattern of global neuronal firing. Using the high temporal resolution of EEG recordings in patients with a severe Acquired Brain Injury (sABI) admitted to an...
