The classical taxonomic methodologies for determining taxa of mushrooms are based primarily on morphological traits. If the mushroom specimens are dried or pulverized, the morphological characteristics are frequently disguised or no longer apparent. Included among these fungi are known to produce psilocybin, which are hard to identify by their macroscopic features. Molecular techniques could...
The authors assess the significance of the rediscovery of Kant's philosophy of mind, which in their view offers valuable insights into the basis of conscious and unconscious mental life, protomental structures and the organisation of the internal world. They draw attention to the importance of distinguishing between brain culture, as represented by the neurosciences in particular, and mind...
This study tested the two main neurocognitive models of dreaming by using cognitive data elicited from REM sleep in normals and narcoleptics. The two models were the "activation-only" view which holds that, in the context of sleep, overall activation of the brain is sufficient for consciousness to proceed in the manner of dreaming (e.g., Antrobus, 1991; Foulkes, 1993; Vogel, 1978); and the...
Not at all self-evident, the so-called isomorphisms between the phenomenology and physiology of dreams have been interpreted by Hobson et al. in an arbitrary manner to state that dreams are stimulated by chaotic brainstem stimulation (an assumption also adopted by Vertes & Eastman). I argue that this stimulation is not chaotic at all; nor does it occur in the absence of control from the...
The formal features of dream characters were studied in a sample of 320 dream reports submitted by 33 adult subjects (13 male, 20 female) of varying ages in a university extension course. Subjects were queried by questionnaire about dream characters immediately after recording their dreams upon awakening in their normal home setting. It was found that 48% of characters represented a named...
Information processing theories of memory and skills can be reformulated in terms of how categories are physically and temporally related, a process called conceptual coordination. Dreaming can then be understood as a story-understanding process in which two mechanisms found in everyday comprehension are missing: conceiving sequences (chunking categories in time as a higher-order...
The concept of transliminality ("a hypothesized tendency for psychological material to cross thresholds into or out of consciousness") was anticipated by William James (1902/1982), but it was only recently given an empirical definition by Thalbourne in terms of a 29-item Transliminality Scale. This article presents the 17-item Revised Transliminality Scale (or RTS) that corrects age and gender...
This study investigated Stambali, a Tunisian trance-dance practiced in Israel as a healing and a demon exorcism ritual by Jewish-Tunisian immigrants. The authors observed the ritual and conducted semi-structured ethnographic interviews with key informants. Content analysis revealed that Stambali is practiced for prophylactic reasons (e.g. repelling the ‘evil eye’), for the promotion of personal...
How can one investigate phenomenal consciousness? As in other areas of science, the investigation of consciousness aims for a more precise knowledge of its phenomena, and the discovery of general truths about their nature. This requires the development of appropriate first-person, second-person and third-person methods. This book introduces some of the creative ways in which these methods can...
Charles Darwin is generally credited with having formulated the first systematic attempt to explain the evolutionary origins and function of the expression of emotions in animals and humans. His ingenious theory, however, was burdened with popular misconceptions about human phylogenetic heritage and bore the philosophical and theoretical deficiencies of the brain science of his era that his...
