Understanding the neural correlates of consciousness has important ramifications for the theoretical understanding of consciousness and for clinical anaesthesia. A major limitation of prior studies is the use of responsiveness as an index of consciousness. We identified a collection of measures derived from unresponsive subjects and more specifically their association with consciousness (any...
Clarifying the mechanisms of loss and recovery of consciousness in the brain is a major challenge in neuroscience, and research on the spatiotemporal organization of rhythms at the brain region scale at different levels of consciousness remains scarce. By applying computational neuroscience, an extended corticothalamic network model was developed in this study to simulate the altered states of...
Humans have asked themselves the question "who am I" from ancient times. Vedic, upanishadic and buddhist philosophers have pointed out over millennia the illusive nature of the individual self, and posit either a no-self, or a universal Self. Vedantic scholars also posit the illusory nature of the universe (Maya) and suggest that the only reality is the knower (Brahman), a view resonating with...
Inducing hallucinations under controlled experimental conditions in non-hallucinating individuals represents a novel research avenue oriented toward understanding complex hallucinatory phenomena, avoiding confounds observed in patients. Auditory-verbal hallucinations (AVH) are one of the most common and distressing psychotic symptoms, whose etiology remains largely unknown. Two prominent...
Contemplative scholarship has recently reoriented attention towards the neuroscientific study of the soteriological ambition of Buddhist practice, 'awakening'. This article evaluates the project of seeking neural correlates for awakening. Key definitional and operational issues are identified demonstrating that: the nature of awakening is highly contested both within and across Buddhist...
Some conscious experiences are more vivid than others. Although perceptual vividness is a key component of human consciousness, how variation in this magnitude property is registered by the human brain is unknown. A striking feature of neural codes for magnitude in other psychological domains, such as number or reward, is that the magnitude property is represented independently of its sensory...
Pesugihan is a mystical ritual carried out by individuals in secret and unreasonable to obtain wealth involving mystical rituals of shamanic practices. The purpose of this research is to find out the psychological dynamics and how to interpret an individual who performs the pesugihan ritual. Data exploration was carried out by analyzing the basic motivations, both intrinsic and extrinsic, from...
The rapid evolution of artificial intelligence, biotechnology, and robotics has reshaped contemporary narratives, prompting a re-evaluation of what it means to be human. Richard Powers’s Galatea 2.2 explores the intersections of artificial intelligence (AI), cognitive science, and posthuman consciousness, engaging deeply with the philosophical and technological implications of human-like...
Abstract This book is about introspection and its use in scientific theorising about the mind. It deals with two connected questions: What is introspection? Does introspection deliver theoretically valuable information about the mind? There is a long history in philosophy and psychology of using introspection to gather data about the mind. Introspection is often held to constitute our best and...
The concept of the brain's own time and space is central to many models and theories that aim to explain how the brain generates consciousness. For example, the temporo-spatial theory of consciousness postulates that the brain implements its own inner time and space for conscious processing of the outside world. Furthermore, our perception and cognition of time and space can be different from...
