Opposite Modulation of the NMDA Receptor by Glycine and S-Ketamine and the Effects on Resting State EEG Gamma Activity: New Insights into the Glutamate Hypothesis of Schizophrenia

International Journal of Molecular Sciences January 18, 2023 Moritz Haaf, Stjepan Curic, Jonas Rauh et al. 9 citations

NMDA-receptor hypofunction is increasingly considered to be an important pathomechanism in schizophrenia. However, to date, it has not been possible to identify patients with relevant NMDA-receptor hypofunction who would respond to glutamatergic treatments. Preclinical models, such as the ketamine model, could help identify biomarkers related to NMDA-receptor function that respond to...

Buddhism and Cognitive (Neuro)Science: An Uneasy Liaison?

Asian Studies January 18, 2023 Sebastjan Vörös

The main aim of this article is to shed light on the intricate relationship between Buddhism and science by focusing on what is becoming an increasingly popular area of contact between the two domains, namely the study of consciousness in the field of cognitive (neuro)science. First, three fundamental ways of approaching the relationship between Buddhism and science are outlined: (a) rejection...

Neural substrates of cognitive impairment in a NMDAR hypofunction mouse model of schizophrenia and rescue by risperidone

bioRxiv January 18, 2023 Cristina Delgado-Sallent, Thomas Gener, Pau Nebot et al. preprint

NMDAR hypofunction is a pathophysiological mechanism relevant for schizophrenia. Acute administration of the NMDAR antagonist phencyclidine (PCP) induces psychosis in patients and animals while subchronic PCP (sPCP) produces cognitive dysfunction for weeks. We investigated the neural correlates of memory and perceptual impairments in mice treated with sPCP and the rescuing abilities of the...

Therapeutic potential of psilocybin: a promising agent in treating major depressive disorder

AIDASCO Reviews January 17, 2023 Dragana Marković, Eleonora Čapelja 2 citations

Major depressive disorder (MDD), also known as clinical depression, is a serious mental disorder and ranks first among psychiatric disorders that dominate the global disease burden. Recently, it was found that psilocybin, active compound derived from psychotropic mushrooms, can relieve depression symptoms rapidly and sustained benefits for several months. Beside MDD, psilocybin can alleviate...

Metacognition and psychosis-spectrum experiences: A study of objective and subjective measures.

Schizophrenia Research January 14, 2023 Emma Palmer‐cooper, Abigail C. Wright, Nicola Mcguire et al.

Background: Metacognition refers to appraising one's thoughts and behaviours. Deficits in metacognition are associated with psychosis-spectrum experiences, such as hallucinations and delusions, in both clinical and non-clinical populations. Assessments of metacognitive function and abilities in clinical populations often vary in administration duration, and subjectivity of scores. This study...

Understanding Physical Processes in Describing a State of Consciousness: A Review

arXiv Preprint Archive January 12, 2023 Charles Johnstone, Prashant S. Alegaonkar preprint

The way we view the reality of nature, including ourselves, depend on consciousness.It also defines the identity of the person, since we know people in terms of their experiences. In general, consciousness defines human existence in this universe. Furthermore, consciousness is associated with the most debated problems in physics such as the notion of observation, observer,in the measurement...

Indigenous-Amazonian Traditional Medicine’s Usage of the Tobacco Plant: A Transdisciplinary Ethnopsychological Mixed-Methods Case Study

Plants January 11, 2023 Ilana Berlowitz, Ernesto García Torres, Caroline Maake et al. 14 citations

Harmful usage of tobacco is a global public health problem associated with adverse health effects and addiction. Yet, in the Peruvian Amazon, the native region of Nicotiana rustica L., this plant is used in remarkably different manners: it is considered a potent medicinal plant, applied in liquid form for oral ingestion to treat mental health problems, a common and ancient healing practice in...

Investigating the "two-hit hypothesis": Effects of prenatal maternal immune activation and adolescent cannabis use on neurodevelopment in mice.

Progress in Neuro-Psychopharmacology and Biological Psychiatry January 10, 2023 Elisa Guma, Lani Cupo, Weiya Ma et al.

Prenatal exposure to maternal immune activation (MIA) and chronic adolescent cannabis use are both risk factors for neuropsychiatric disorders. However, exposure to a single risk factor may not result in major mental illness, indicating that multiple exposures may be required for illness onset. Here, we examine whether combined exposure to prenatal MIA and adolescent...

Georg Northoff's Neurophilosophical Approach

Rudn Journal of Philosophy January 10, 2023 Anastasiia A. Zhudina 1 citation

When trying to give a universal definition to the term “neurophilosophy,” difficulties arise, since each researcher who identifies himself as a member of this field sets his own definition. The common thing for the work of “neurophilosophers” can be described as an interdisciplinary approach, which takes into account the achievements in the field of consciousness research of both philosophical...

Interaction of psychedelic tryptamine derivatives with a lipid bilayer

Chemistry and Physics of Lipids January 7, 2023 Fateme Zohairi, Himanshu Khandelia, Ali Asghar Hakami Zanjani 20 citations

Naturally occurring psychedelics have been used for a long time as remedies or in religious ceremonies and recreational activities. Recent studies have proven the therapeutic potential of some psychedelic compounds to safely treat a wide range of diseases such as anxiety, depression, migraine, and addiction. It is hypothesized that psychedelic compounds like tryptamines can exert their effects...
