Into the Darkness: Deep Caves in the Ancient Near East

Journal of Landscape Ecology December 1, 2017 Michael Freikman 5 citations

Abstract In this paper I will present the assemblage of pottery vessels and objects of luxury dated to the Neolithic and Chalcolithic periods discovered in the Zarda Cave in Western Samaria, Israel. The context in which this assemblage was found is strongly reminiscent of other proto-historic depositions found in Israel. As determent of objects of value found in the deep and dark caves cannot...

The Paranormal as Mental Aberration: Near Death and Out-of-Body Experiences

Routledge eBooks November 22, 2017 Eric Carlton

Psychologists and others have become particularly intrigued by what are commonly referred to as altered states of consciousness, more technically known as dissociative states. There is very little evidence one way or another for supposing that genetic/other biological/hereditary factors might predispose a person to dissociative reactions which may take many forms. The paranormal is not a coping...

Prophecy and Ecstasy

November 22, 2017 Martti Nissinen

Abstract The prophetic performance is typically associated with a specific state of mind variously called ecstasy, trance, or possession. This chapter demonstrates that an altered state of consciousness appears as a prerequisite of the prophetic performance in ancient Near Eastern, Greek, and biblical texts. One of the designations of Mesopotamian prophets, muḫḫûm/maḫḫû, implies an ecstatic...

LSD modulates effective connectivity and neural adaptation mechanisms in an auditory oddball paradigm.

Neuropharmacology November 20, 2017 Christopher Timmermann, Meg J. Spriggs, Mendel Kaelen et al. 83 citations

Under the predictive coding framework, perceptual learning and inference are dependent on the interaction between top-down predictions and bottom-up sensory signals both between and within regions in a network. However, how such feedback and feedforward connections are modulated in the state induced by lysergic acid diethylamide (LSD) is poorly understood. In this study, an auditory oddball...

A Deep-Dream Virtual Reality Platform for Studying Altered Perceptual Phenomenology

Scientific Reports November 16, 2017 Keisuke Suzuki, Warrick Roseboom, David J. Schwartzman et al. 111 citations

Altered states of consciousness, such as psychotic or pharmacologically-induced hallucinations, provide a unique opportunity to examine the mechanisms underlying conscious perception. However, the phenomenological properties of these states are difficult to isolate experimentally from other, more general physiological and cognitive effects of psychoactive substances or psychopathological...

Western constructions of magic

November 15, 2017 Damon Zacharias Lycourinos

This chapter begins by examining the origins and development of the anthropological study of magic to identify factors and mentalities that define magic as a distinctive category of ideas and practices. In continuum, the study of modern magic is addressed from the perspective of the contemporary academic study of Western esotericism to consider how magic has traditionally been treated as...

Hypnotic susceptibility and affective states in bipolar I and II disorders.

BMC Psychiatry November 9, 2017 Bingren Zhang, Jiawei Wang, Qisha Zhu et al.

Background: Highly hypnotizable individuals have impaired executive function, elevated motor impulsivity and increased emotional sensitivity, which are sometimes found in bipolar disorder patients. It is then reasonable to assume that certain aspects of hypnotic susceptibility differ with the types of bipolar disorder. Methods: The Stanford Hypnotic Susceptibility Scale: Form C (SHSS:C) test,...

LSD Increases Primary Process Thinking via Serotonin 2A Receptor Activation

Frontiers in Pharmacology November 8, 2017 Rainer Kraehenmann, Dan Pokorný, Helena Aicher et al. 115 citations

Rationale: Stimulation of serotonin 2A (5-HT2A) receptors by lysergic acid diethylamide (LSD) and related compounds such as psilocybin has previously been shown to increase primary process thinking – an ontologically and evolutionary early, implicit, associative, and automatic mode of thinking which is typically occurring during altered states of consciousness such as dreaming. However, it is...

The Hallucination Machine: A Deep-Dream VR platform for Studying the Phenomenology of Visual Hallucinations

Altered states of consciousness, such as psychotic or pharmacologically-induced hallucinations, provide a unique opportunity to examine the mechanisms underlying conscious perception.
