An evidence-based critical review of the mind-brain identity theory.

Frontiers in Psychology 2023 Marco Masi 14 citations

In the philosophy of mind, neuroscience, and psychology, the causal relationship between phenomenal consciousness, mentation, and brain states has always been a matter of debate. On the one hand, material monism posits consciousness and mind as pure brain epiphenomena. One of its most stringent lines of reasoning relies on a 'loss-of-function lesion premise,' according to which, since brain...

Ketamine-assisted psychotherapy treatment of chronic pain and comorbid depression: a pilot study of two approaches.

Frontiers in Pain Research 2023 Daniella Batievsky, Michelle Weiner, Shari B Kaplan et al. 8 citations

Chronic pain and depression diagnoses are skyrocketing. There is an urgent need for more effective treatments. Ketamine was recently established to alleviate pain and depression, but many gaps remain in the scientific literature. This paper reports the findings of an observational preliminary study that explored the efficacy of ketamine-assisted psychotherapy (KAPT) for chronic pain/major...

The cloud of unknowing: Cognitive dedifferentiation in whole-body perceptual deprivation.

Progress in Brain Research 2023 Michele Pellegrino, Joseph Glicksohn, Fabio Marson et al. 3 citations

An altered sensory environment, especially a homogeneous one like a ganzfeld, can induce a wide range of experiences in people immersed in it. The ganzfeld of our current focus is the OVO Whole-Body Perceptual Deprivation chamber (OVO-WBPD). Previous literature has found this specific immersive environment to be capable of softening and dissolving perception of boundaries across time and...

Evaluating passive physiological data collection during Spravato treatment.

Frontiers in Digital Health 2023 Todd M Solomon, Matus Hajduk, Martin Majernik et al. 1 citation

Spravato and other drugs with consciousness-altering effects show significant promise for treating various mental health disorders. However, the effects of these treatments necessitate a substantial degree of patient monitoring which can be burdensome to healthcare providers and may make these treatments less accessible for prospective patients. Continuous passive monitoring via digital devices...

Dissociation and other trauma symptomatology are linked to imbalance in the competing neurobehavioral decision systems.

Frontiers in Psychology 2023 Julia C. Basso, Medha K. Satyal, Kevin L Mckee et al. 5 citations

Dissociation is a conscious state characterized by alterations in sensation and perception and is thought to arise from traumatic life experiences. Previous research has demonstrated that individuals with high levels of dissociation show impairments in cognitive-emotional processes. Therefore, using the Competing Neurobehavioral Decisions System (CNDS) theory, we used statistical modeling to...

When art therapy went chemical: Alfred Bader, pharmacology, and art brut, c.1950-1970s.

Historia, Ciencias, Saude--Manguinhos 2023 Jelena Martinovic 2 citations

This article analyzes how psychopharmacology transformed the relationship between art and psychiatry. It outlines a novel genealogy of art therapy, repositioning its origins in the context of evolving clinical practices and discourses on mind-altering drugs. Evaluating the use of psychotropic drugs in connection with psychopathology of art in the first half of the twentieth century, the article...

Psychedelics, entropic brain theory, and the taxonomy of conscious states: a summary of debates and perspectives.

Neuroscience of Consciousness 2023 Sidath Rankaduwa, Adrian M. Owen 21 citations

Given their recent success in counseling and psychiatry, the dialogue around psychedelics has mainly focused on their applications for mental health. Insights from psychedelic research, however, are not limited to treating mental health, but also have much to offer our current understanding of consciousness. The investigation of psychedelic states has offered new perspectives on how different...

Altered State of Consciousness and Mental Imagery as a Function of N, N-dimethyltryptamine Concentration in Ritualistic Ayahuasca Users

Journal of Cognitive Neuroscience 2023 Johannes G. Ramaekers, Pablo Mallaroni, Lilian Kloft et al. 15 citations

Abstract Consumption of the psychedelic brew ayahuasca is a central ritualistic aspect of the Santo Daime religion. The current observational, baseline controlled study was designed to assess whether members (n = 24) of the Santo Daime church would show enhanced capacity for mental imagery during an ayahuasca experience. In addition, this study assessed whether the effects of ayahuasca on...

Next generation antidepressants with novel mechanisms for treatment resistant depression.

Progress in Brain Research 2023 Mu-Hong Chen, Pei-Chi Tu, Tung-Ping Su 3 citations

Evidence has suggested that the modulation of N-methyl-d-aspartate receptors (NMDARs) and 5-hydroxytryptamine receptors (5-HTRs) via the psychedelic drugs, such as ketamine and psilocybin, rapidly alters the state of consciousness and the neuroplasticity. The United State Food and Drug Administration approved the indications of esketamine for treatment-resistant depression (TRD) in 2019 and...

Potential therapeutic effects of an ayahuasca-inspired N,N-DMT and harmine formulation: a controlled trial in healthy subjects.

Frontiers in Psychiatry 2023 Helena Aicher, Michael J Mueller, Dario Dornbierer et al. 34 citations

There is growing scientific evidence for the therapeutic benefits of the Amazonian plant-based psychedelic "ayahuasca" for neuropsychiatric disorders such as depression and anxiety. However, there are certain challenges when incorporating botanical ayahuasca into biomedical research and clinical therapy environments. Formulations inspired by ayahuasca, which contain specific and standardized...
