Although there is no recognised definition of consciousness, many researchers refer back to the famous question, ‘What is it like to be a bat?’ If there is anything it is like for the bat, that is what is meant by being conscious. This is also called ‘phenomenal consciousness’ (P-consciousness) or ‘phenomenality’ and is sometimes contrasted with ‘access consciousness’ (A-consciousness)....
How do we lose and regain consciousness? The space between healthy wakefulness and unconsciousness encompasses a series of gradual and rapid changes in brain activity. In this thesis, I investigate computational measures applicable to the electroencephalogram to quantify the loss and recovery of consciousness from the perspective of modern theoretical frameworks. I examine three different...
The coupling between respiration and neural activity within olfactory areas and hippocampus has recently been unambiguously demonstrated, its neurophysiological basis sustained by the well-assessed mechanical sensitivity of the olfactory epithelium. We herein hypothesize that this coupling reverberates to the whole brain, possibly modulating the subject's behavior and state of consciousness....
The introduction examines contemporary debates in neuroscience and the philosophy of mind, demonstrating the conceptual impasses inevitable when writers adopt extreme rhetorical positions about the so-called “cerebral subject”—for example, “you are your brain” or “you are not your brain.” Literary works, literary criticism, and the neurohumanities respond to such debates by eschewing reductive...

This chapter examines the relationship between mind and brain in general. It suggests that the classical mind-body problem has been redefined by cognitive scientists as the problem of consciousness. The mind-body problem is a philosophical conundrum that dates back to classical antiquity, and probably beyond. David Chalmers—one of the philosophers participating in the interdisciplinary field of...

\n A temporalidade compõe os atos da pessoa no mundo. A subjetividade assume papel importante, a partir dela é que o tempo adquire sentido e significado. Desta forma, a percepção subjetiva do tempo torna-se essencial para a percepção da realidade, delineando uma distinção entre o decurso temporal dos eventos vividos ao longo da vida, o que implica que o processamento da informação temporal é...
How do emerging adults experience mindfulness and compassion? The goals of this study were to (1) evaluate the effectiveness of a mindfulness curricular intervention and (2) examine how students interpreted their experience. We delivered a mindfulness curriculum to 24 college students who meditated twice a week for 7 weeks. Students completed a survey at the beginning and end of the course...
David Chalmers is a professor of philosophy and neural science at New York University. He received his PhD in philosophy and cognitive science from Indiana University in 1993 and has held positions at University of California, Santa Cruz, University of Arizona, and Australian National University. He helped to found the Association for the Scientific Study of Consciousness and co-directs the...
N,N-dimethyltryptamine (DMT) is a powerful serotonergic psychedelic whose exogenous administration elicits striking psychedelic effects in humans. Studies have identified DMT and analogous compounds (e.g., 5-hydroxy-DMT, 5-methoxy-DMT) alongside of an enzyme capable of synthesizing DMT endogenously from tryptamine, indolethylamine-N-methyltransferase (INMT), in human and several other mammalian...
This chapter studies a major debate that has emerged in the second-half of the twentieth century between scholars of mysticism. The debate is between perennialist scholars and constructivist scholars. Perennialism sees mystical experiences as transcending culture, language, and time-period, and pointing to a unified spiritual experience among various peoples, while constructivism sees mystical...
