The aim of this study was to investigate if the highly sensitive personality variable affects the occurrence of mystical experiences and degree of altered states of consciousness during sensory isolation in flotation-tank. Forty-eight persons (20 males, 28 females) were included. Background variables and the Highly Sensitive Personality Scale (HSP) were assessed. The independent variable was...

Previous studies have documented that in a substantial minority of individuals with depersonalization disorder, onset is first triggered by illicit drug ingestion. The goal of this study was to systematically compare a large sample of individuals with drug-initiated (D) versus non-drug-initiated (ND) chronic depersonalization. We conducted an internet survey of 394 adults endorsing DSM-IV-TR...

Ecstasy or 3,4-methylenedioxymethamphetamine (MDMA) is a frequently (ab)used recreational drug for its acute euphoric effects but on the long-term may cause neurotoxic damage to serotonin (5-hydroxytryptamine; 5-HT) nerve endings in the brain. Since decreased brain 5-HT function has been strongly associated with several impulse control disorders like hostility and violent aggression, ecstasy...

Previously, we proposed a superposition-based hypothesis (H1) in the dual-aspect-dual-mode PE-SE framework to address the Type-1 explanatory gap (how subjective experiences (SEs) aspect of consciousness can emerge from non-experiential matter) as follows: (1) fundamental entities (strings or elementary particles: fermions and bosons) have material and mental aspects and are carriers of...

ABSTRACTThis study, which is based upon ethnographic data collected between 1999 and 2008 in Nepal, examines the connection between the shaman's altered states of consciousness (ASC; i.e., what goes on inside the healer's mind/brain) and therapeutic changes that take place in the patient's mind/body. Unlike other studies that primarily emphasize the shaman's internal psychological state, this...

In 1957, the word 'psychedelic' entered the English lexicon from a rather unexpected location: an asylum superintendent working on the Canadian prairies in one of the provincial mental hospitals in Saskatchewan. During the 1950s Saskatchewan-based researchers engaged in political and psychiatric reforms that brought international attention to their work in a relatively isolated geographic...

We propose a translational approach to the study of anorexia nervosa (AN) based on our human subject studies where there are characteristic elevations in 5-HT(1A) receptor binding, associated harm avoidance behaviors, reduced impulsivity, and comorbid anxiety disorders. Towards this goal, the hyponeophagia assay was implemented whereby food-deprived mice show increased latency to begin feeding...

In trying to improve clinician communication skills, we have often heard clinicians at every level admonished to "use silence," as if refraining from talking will improve dialogue. Yet we have also noticed that this "just do it," behavior-focused "use" of silence creates a new, different problem: the clinician looks uncomfortable using silence, and worse, generates a palpable atmosphere of...

Pyramidal neurons in layer 5 of the cerebral cortex are involved in learning and memory and have complex connections with other neurons through a very large array of dendrites. These dendrites can switch between long term depression and long term potentiation depending on global summation of various inputs. The plasticity of the input into pyramidal neurons makes the neuronal output variable....

MacIntyre (Encyclopedia of Philosophy, p. 296) voices two representative philosophical criticisms of Jung’s theorizing: (1) the existence of the collective unconscious cannot be decided by any possible observation or experiment, and (2) ontological claims about the contents of the psyche are ambiguous. Jung states, “The content of the collective unconscious is made up essentially of...
