Perceptual Diversity: Is Polyphasic Consciousness Necessary for Global Survival?
Anthropology of Consciousness March 1, 2001 Tara W. Lumpkin
Perceptual diversity allows human beings to access knowledge through a variety of perceptual processes, rather than merely through everyday waking reality. Many of these perceptual processes are transrational altered states of consciousness (meditation, trance, dreams, imagination) and are not considered valid processes for accessing knowledge by science (which is based primarily upon...
L'alternative des savoirs autochtones au « tout ou rien » thérapeutique
Psychotropes 2001 Jacques Mabit 6 citations
Résumé À la maladresse avec laquelle l’occidental induit des modifica~tions de sa conscience, les médecines ancestrales répondent par un savoir~faire des plus sophistiqués où non seulement l’induction contrôlée d’états non-ordinaire de la conscience n’est pas dommageable mais permet même de faire face au développement moderne du phénomène toxicomaniaque. À partir de son expérience clinique en...
Rapid-eye-movement sleep involves the memory-conversion circuits in a brain model.
Medical Hypotheses November 2000 C W Wong
People can remember the content of a dream in rapid eye movement (REM) sleep but cannot do so in slow-wave sleep. According to a brain model, memory is stored in encoding synapses as presynaptic axonal 'on-off' patterns and modulating synapses help encoding synapses convert short-term memory into long-term memory. These lead to the hypothesis that REM sleep involves modulating synapses of the...
Anesthesia, neural information processing, and conscious awareness.
Consciousness and Cognition September 2000 P Cariani
Possible systemic effects of general anesthetic agents on neural information processing are discussed in the context of the thalamocortical suppression hypothesis presented by Drs. Alkire, Haier, and Fallon (this issue) in their PET study of the anesthetized state. Accounts of the neural requisites of consciousness fall into two broad categories. Neuronal-specificity theories postulate that...
Body and Consciousness: A Conversation with Antonio Damasio
Anthropology of Consciousness September 1, 2000 Grant Jewell Rich
This is an interview with neurologist Antonio Damasio, MD, PhD, whose work on consciousness has influenced scholars in a variety of fields, including anthropology. Damasio addresses a number of issues, including the neurobiology of altered states, the neurology of flow and other optimal, pleasurable states, and the potential to identify biological markers that are common to the experience of...
Awareness may be existence as well as (higher-order) thought
Behavioral and Brain Sciences April 1, 2000 Jordan B. Peterson
Rolls attributes to consciousness the functions of reflection, planning, and error-correction. Neuropsychologically grounded cybernetic theory provides an analogous, broader conceptualization: consciousness constructs goals (and plans), alters the valence of goal-related phenomena, registers error-signals, and explores unexpected circumstances (reconfiguring goals and plans as necessary)....
Flying in Nightmares - A Neglected Phenomenon
PsyDok Dokumentenserver für die Psychologie 2000 Rainer Schönhammer 3 citations
It is widely supposed in the scientific and popular literature on dreams that flying in dreams is of mostly delightful character. Domhoff (1996) recently emphasised the highly positive feelings experienced in flying dreams although he mentions a turn to apprehension later in the dream ("crashing", "coming down"). In my research (an interview-sample of flying dreams) I met flying experiences in...
Acetylcholine in mind: a neurotransmitter correlate of consciousness?
Trends in Neurosciences June 1999 E Perry, M Walker, J Grace et al.
The cholinergic system is one of the most important modulatory neurotransmitter systems in the brain and controls activities that depend on selective attention, which are an essential component of conscious awareness. Psychopharmacological and pathological evidence supports the concept of a 'cholinergic component' of conscious awareness. Drugs that antagonize muscarinic receptors induce...
Altered States, Conflicting Cultures: Shamans, Neo‐shamans and Academics
Anthropology of Consciousness June 1, 1999 Robert J. Wallis
In anthropology, archaeology and popular culture, Shamanism may be one of the most used, abused and misunderstood terms, to date. Researchers are increasingly recognizing the socio‐political roles of altered states of consciousness and shamanism in past and present societies, yet the rise of Neo‐shamanism and its implications for academics and their subjects of study are consistently neglected....
