DİJİTAL TASARIMDA KULLANICI DENEYİMİ SUNAN PSİKEDELİK YAKLAŞIMLAR

Sanat ve Tasarım Dergisi June 21, 2022 Başak Çakmak 1 citation

Kullanıcı deneyimi sunan web sayfaları gerçekten de kullanıcısının ruhsal ve psikolojik büyüme arzusuna etki edebilir mi? Zihin ve ruhun tezahür etmesini sağlayan halüsinojenler gibi web sayfaları da bunun gerçekleşmesini sağlayabilir. Rüyaların hayal gücünün yakıtı olması gibi psikedelik sanat da dijital tasarımın katalizörüdür. Dijital tasarım, doğrusal süreklilikte olan bilinç durumunu...

Application of machine learning and complex network measures to an EEG dataset from DMT experiments

medRxiv June 16, 2022 Caroline L. Alves, Thaise G. L. de O. Toutain, Joel Augusto Moura Porto et al. preprint

There is a growing interest in the medical use of psychedelic substances as preliminary studies using them for psychiatric disorders have shown positive results. In particularly, one of these substances is N,N-dimethyltryptamine (DMT) an agonist serotonergic psychedelic that can induce profound alterations in state of consciousness. In this work, we propose a computational method based on...

The Effect of Transcranial Direct Current Stimulation on Error Rates in the Distractor-Induced Deafness Paradigm

Brain Sciences June 4, 2022 Lars Michael, Ana Böke, Henry Ipczynski 1 citation

To further understand how consciousness emerges, certain paradigms inducing distractor-induced perceptual impairments are promising. Neuro-computational models explain the inhibition of conscious perception of targets with suppression of distractor information when the target and distractor share the same features. Because these gating mechanisms are controlled by the prefrontal cortex,...

Alteration of Consciousness by Anaesthetics: A Multiscale Modulation from the Molecular to the Systems Level

Journal of Consciousness Studies June 1, 2022 Marco Cavaglià, E. A. Zizzi, S. Dombrowski et al.

General anaesthesia has been used in medical practice since the mid-nineteenth century, but its pharmacological mechanism of action is still not entirely clear. In a top-down approach, investigations probe smaller and smaller scales to shed light on how anaesthetics disrupt or alter neural activity, ultimately resulting in loss of consciousness. In the past few decades, advances in neuroscience...

Cortical Acetylcholine Levels Correlate With Neurophysiologic Complexity During Subanesthetic Ketamine and Nitrous Oxide Exposure in Rats.

Anesthesia & Analgesia June 1, 2022 Michael A. Brito, Duan Li, Christopher W Fields et al.

Neurophysiologic complexity has been shown to decrease during states characterized by a depressed level of consciousness, such as sleep or anesthesia. Conversely, neurophysiologic complexity is increased during exposure to serotonergic psychedelics or subanesthetic doses of dissociative anesthetics. However, the neurochemical substrates underlying changes in neurophysiologic complexity are...

A Phase 1, Dose-Ranging Study to Assess Safety and Psychoactive Effects of a Vaporized 5-Methoxy-N,N-Dimethyltryptamine Formulation (GH001) in Healthy Volunteers

European Psychiatry June 1, 2022 Johannes T. Reckweg, Natasha L. Mason, Cees van Leeuwen et al. 3 citations

Introduction 5-Methoxy-N,N-Dimethyltryptamine (5-MeO-DMT) is a tryptamine with ultra-rapid onset and short duration of psychedelic effects. Prospective studies for other tryptamines have suggested beneficial effects on mental health outcomes. Objectives In preparation for a study in patients with depression, the present study GH001-HV-101 aimed to assess the impact of four different dose levels...

role of psychedelics in supernatural experience formation

International Journal of Health Sciences May 31, 2022 Mahdi Eftekhar

The use of psychedelics to form supernatural experiences has been and is common. Because such substances cause changes in states of consciousness and create a state similar to trance and the departure of the soul from the body or a kind of altered perception of facts. But in some cases, some additional facts are perceived. The question is, to what extent can the use of these materials be a way...

Neural mechanisms underlying psilocybin’s therapeutic potential – the need for preclinical in vivo electrophysiology

Journal of Psychopharmacology May 30, 2022 Rebecca Smausz, Joanna C. Neill, John Gigg 60 citations

Psilocybin is a naturally occurring psychedelic compound with profound perception-, emotion- and cognition-altering properties and great potential for treating brain disorders. However, the neural mechanisms mediating its effects require in-depth investigation as there is still much to learn about how psychedelic drugs produce their profound and long-lasting effects. In this review, we outline...

Spatiotemporal Mapping of Online Interest in Cannabis and Popular Psychedelics before and during the COVID-19 Pandemic in Poland

International Journal of Environmental Research and Public Health May 29, 2022 Ahmed Al-Imam, Marek A Motyka, Zuzanna Witulska et al. 7 citations

Background: Psychedelics represent a unique subset of psychoactive substances that can induce an aberrant state of consciousness principally via the neuronal 5-HT2A receptor. There is limited knowledge concerning the interest in these chemicals in Poland and how they changed during the pandemic. Nonetheless, these interests can be surveyed indirectly via the web. Objectives: We aim to conduct a...

The altered state of consciousness induced by Δ9-THC.

Consciousness and Cognition May 28, 2022 Conor H. Murray, Bhargav Srinivasa Desikan 20 citations

Altered states of consciousness (ASC) provide an opportunity for researchers to study the neurophysiological basis of changes in phenomenal experience. Δ9-tetrahydrocannabinol (THC) is the primary psychoactive constituent of cannabis, however whether the effects of THC include ASC features that are shared with other ASC induction mechanisms, such as classical psychedelics, has not been...
