Most men hold themselves in high regard and care about staying alive. Someone is intent on interrupting the decay of the organism, on counterfeiting the genes that preside over old age and death, but leaves the threat of disease and accidents intact. Artificial intelligence prophesies the advent of an automaton that will imitate man’s behavior in such a precise way as not to distinguish one...
Entropy July 19, 2023 Andrea Buccellato, Yasir Çatal, Patrizia Silvia Bisiacchi et al. 3 citations
Time delays are a signature of many physical systems, including the brain, and considerably shape their dynamics; moreover, they play a key role in consciousness, as postulated by the temporo-spatial theory of consciousness (TTC). However, they are often not known a priori and need to be estimated from time series. In this study, we propose the use of permutation entropy (PE) to estimate time...

Quantifying neural activity in natural conditions (i.e. conditions comparable to the standard clinical patient experience) during the administration of psychedelics may further our scientific understanding of the effects and mechanisms of action. This data may facilitate the discovery of novel biomarkers enabling more personalized treatments and improved patient outcomes. In this single-blind,...

Background Psychedelic drug experiences are shaped by current-moment contextual factors, commonly categorized as internal (set) and external (setting). Potential influences of past environments, however, have received little attention. Aims To investigate how previous environmental stimuli shaped the experiences of patients receiving ketamine for treatment-resistant depression (TRD), and...

If I see, hear, or touch a sparrow, the sparrow seems real to me. Unlike Bigfoot or Santa Claus, it seems to exist; I will therefore judge that it does indeed exist. The “sense of existence” refers to the kind of awareness that typically grounds such ordinary judgments of existence or “reality.” The sense of existence has been invoked by Humeans, Kantians, Ideologists, and the phenomenological...

It is widely accepted that there is a visual field, but the analogous notion of an auditory field is rejected by many philosophers on the grounds that the metaphysics or phenomenology of audition lack the necessary spatial structure. In this paper, I argue that many of the common objections to the existence of an auditory field are misguided and that, contrary to a tradition of philosophical...

La structure du comportement details consciousness-nature relations by navigating between realist and intellectualist alternatives. A phenomenological reading of form guides its attempt to formulate a view that does not reduce consciousness to matter or perceptual structure to a product of mind. I show that this strategy relies on hitherto overlooked idealist commitments. Forms are perceived...

BACKGROUND: Pharmacological and nonpharmacological methods of inducing altered states of consciousness (ASCs) are becoming increasingly relevant in the treatment of psychiatric disorders. While comparisons between them are often drawn, to date no study has directly compared their neural correlates. METHODS: To address this knowledge gap, we directly compared 2 pharmacological methods...

To date, no scientific study has found reliable evidence of an afterlife; the mechanism of consciousness is two of the most challenging questions. Here, I show the hypotheses for consciousness and the probability of an afterlife through three simple thought experiments and theoretical evidence. I demonstrate the problems of consciousness, intelligence, and the relationship of the brain with...

主観意識と客観的な物質としての脳は、全く異なる世界に属すのだろうか? 意識の中身であるクオリアと脳はいかに関係しているのか? 意識と脳の問題は、科学的な興味に留まらず、現実社会における人の気持ちの理解の困難に伴う問題にも直接関わる。意識のクオリアは、客観的な言語で定義することすら難しいため、従来の意識研究では、知覚刺激を固定し、経験を「見えた・見えない」という二値的な判断に還元し、その神経相関の探求を試みた。近年、我々は視覚クオリア間の類似度を大規模に計測することでクオリアの構造を特徴づけ、その神経相関とその情報構造を明らかにする新パラダイムを確立した。本領域は、現象学・発達・構成論を加え、知覚と感情クオリアに集中することで、クオリア構造学を創成する。本領域の成果は、他者意識の理解や、動物や人工物の意識理解など、一般社会へも広く還元されうる答えを生み出す新融合領域の創成である。
