Does the concept of ″altered states of consciousness″ rest on a mistake?

Block (2002) has argued that the multiplicity of meanings ascribed to consciousness is due to the erroneous treatment of very different concepts as a single concept. Block distinguished four notions of consciousness intended to encapsulate the various meanings attributed to the term: phenomenal, access, self, and monitoring consciousness. We argue that what is common to all of these definitions is the implicit distinction between consciousness and the content of consciousness. We critically examine the term “altered state of consciousness” and argue that affixing the qualifier “altered state” to consciousness results in a theoretical confusion of consciousness and its content, that is, consciousness is mistaken for the content of consciousness. We refer to this as the consciousness/content fallacy and argue that it may be avoided if one supplants “altered states of consciousness” with “altered pattern of phenomenal properties,” an extrapolation of the term “phenomenal field.” Implications of the consciousness/content fallacy for theory and research are also considered.

Brain sources of EEG gamma frequency during volitionally meditation-induced, altered states of consciousness, and experience of the self.

Multichannel EEG of an advanced meditator was recorded during four different, repeated meditations. Locations of intracerebral source gravity centers as well as Low Resolution Electromagnetic Tomography (LORETA) functional images of the EEG 'gamma' (35-44 Hz) frequency band activity differed significantly between meditations. Thus, during volitionally self-initiated, altered states of consciousness that were associated with different subjective meditation states, different brain neuronal populations were active. The brain areas predominantly involved during the self-induced meditation states aiming at visualization (right posterior) and verbalization (left central) agreed with known brain functional neuroanatomy. The brain areas involved in the self-induced, meditational dissolution and reconstitution of the experience of the self (right fronto-temporal) are discussed in the context of neural substrates implicated in normal self-representation and reality testing, as well as in depersonalization disorders and detachment from self after brain lesions.

Altered states of consciousness are related to higher sexual responsiveness

Altered states of consciousness lead to profound changes in the sense of self, time and space. We assessed how these changes were related to sexual responsiveness during sex. 116 subjects reported (a) intensity of awareness concerning body, space and time, and (b) satisfaction, desire, arousal, and orgasm occurrence. We differentiated vaginal intercourse orgasm from noncoital orgasm. Female vaginal intercourse orgasm was further differentiated as with or without concurrent clitoral masturbation. Overall, sexual responsiveness was related to greater body awareness and lesser time and space awareness. Satisfaction, desire, and arousal were especially associated with less time awareness in women. Female orgasms during vaginal intercourse were related to greater body awareness and lesser time awareness, but noncoital orgasms were unrelated. Our findings provide empirical support for the hypotheses that altered states of consciousness with attentional absorption are strongly related to sexual responsiveness in women, and to a lesser extent in men.

Global positioning systems : altered representations of place

Global Positioning Systems: altered representations of place, presents an exegesis from the practice led research submitted for the degree of Master of Fine Art at the Victorian College of the Arts. The thesis proposes a particular understanding of altered states of consciousness that is relevant to my practice.  This is outlined by Charles Tart and supported by the Altered States of Consciousness Consortium and explores a psycho-aesthetic experiences and does not involved transcendental states or spiritual associations. These experiences are transformed by an exhaustive application of digital technologies, where mosaic-like complexity emerges that induces sustained disorientation and surrounds a viewer in an immersive space.

Conceptualizing craving : extrapolations from consciousness studies

The key definitional elements of the concept of craving remain highly contentious amongst addiction researchers. We argue that attempts to operationalize the craving construct may benefit from the conceptual and methodological advances that have occurred in the field of consciousness studies. Specifically, it is contended that the concept of craving cannot be fully articulated in the absence of a consideration of Husserl's notion of the intentional structure of human consciousness and related concepts such as phenomenology, discrete states of consciousness and altered states of consciousness. Extrapolating from the consciousness studies literature, we formulate numerous suggestions for future research intended to facilitate the operationalization of craving experiences.

Towards a transpersonal psychology of Daoism

Daoism (Taoism) is a collection of Chinese philosophical beliefs and psychospiritual practices with a history of thousands of years, and a living community that stretches throughout East Asia. I will argue that Daoism and its corresponding texts such as those included in the Daozang provide a wealth of material regarding trans-egoic experiences (e.g., unitive absorption in the Dao), that may enhance Western psychologists’ understanding of transpersonal phenomena. Curiously, however, despite the obvious points of intersection between Daoism and transpersonal psychology (e.g., a mutual interest in phenomena typically referred to as altered states of consciousness), to date transpersonal psychologists have neglected to investigate Daoism. Indeed, the majority of published research concerning the relationships between Daoism and Western psychology has been undertaken from within the Jungian analytic and humanistic psychological movements. After reviewing this literature, I will formulate various proposals for future empirical studies that may interest transpersonal psychologists.

Modulating the rate and rhythmicity of perceptual rivalry alternations with the mixed 5-HT2A and 5-HT1A agonist psilocybin

Binocular rivalry occurs when different images are presented simultaneously to corresponding points within the left and right eyes. Under these conditions, the observer's perception will alternate between the two perceptual alternatives. Motivated by the reported link between the rate of perceptual alternations, symptoms of psychosis and an incidental observation that the rhythmicity of perceptual alternations during binocular rivalry was greatly increased 10 h after the consumption of LSD, this study aimed to investigate the pharmacology underlying binocular rivalry and to explore the connection between the timing of perceptual switching and psychosis. Psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine, PY) was chosen for the study because, like LSD, it is known to act as an agonist at serotonin (5-HT)(1A) and 5-HT2A receptors and to produce an altered state sometimes marked by psychosis-like symptoms. A total of 12 healthy human volunteers were tested under placebo, low-dose ( 115 mg/kg) and high-dose ( 250 mg/kg) PY conditions. In line with predictions, under both low- and high-dose conditions, the results show that at 90 min postadministration ( the peak of drug action), rate and rhythmicity of perceptual alternations were significantly reduced from placebo levels. Following the 90 min testing period, the perceptual switch rate successively increased, with some individuals showing increases well beyond pretest levels at the final testing, 360 min postadministration. However, as some subjects had still not returned to pretest levels by this time, the mean phase duration at 360 min was not found to differ significantly from placebo. Reflecting the drug-induced changes in rivalry phase durations, subjects showed clear changes in psychological state as indexed by the 5D-ASC ( altered states of consciousness) rating scales. This study suggests the involvement of serotonergic pathways in binocular rivalry and supports the previously proposed role of a brainstem oscillator in perceptual rivalry alternations and symptoms of psychosis.

Los estados modificados de conciencia y su uso en la psicología contemporánea

La conciencia, sus diversos estados y las propiedades específicas de estado han sido materia de indagación en prácticamente todas las culturas. Como producto de ello, se han generado multiplicidad de perspectivas sobre el valor de estos estados de conciencia y sobre los modos adecuados de producirlos y utilizarlos. A éstos últimos se les conoce como prácticas de transformación o tecnologías de la conciencia. En el presente trabajo, luego de presentar las posturas contemporáneas básicas utilizadas para el estudio de la conciencia, se revisan las concepciones que sobre ella surgen desde la psicología transpersonal y en el budismo mahayana. Le sigue la presentación del concepto de estados y estados alterados de conciencia en la psicoterapia. Tras discutir la noción de prácticas de transformación de la conciencia se concluye con una presentación más detallada de la meditación y la oración como ejemplos de tecnologías de conciencia utilizadas como medio de sanación y de crecimiento personal.

Imagery cultivation vs. noise reduction : shamanic-like journeying as a psi-conducive alternative to the Ganzfeld protocol

Historically, psi effects have been linked to altered states of consciousness (ASCs; Bem and Honorton, 1994). In this context, arguably the most widely used technique is the Ganzfeld. However, in recent times, scholars (e.g., Alvarado, 1998; Braud, 2005; Scimeca, Boca, and Iannuzzo, 2001) have formulated cogent arguments that cast doubt on whether the Ganzfeld is, in fact, an ASC that is psi-conducive. Consequently, it may prove prudent to investigate other conditions that induce ostensible ASCs that are purportedly psi-conducive, and it would be wise to get feedback from test participants in these states. In this theoretical paper, we propose that psi effects may be enhanced (i.e., strengthened) using a shamanic-like treatment. On that basis, we argue that parapsychologists must go beyond the assumption that psi effects are optimised under conditions that are inherently passive procedures, and foster techniques that require cognitive action from test participants.

Light the towel : narrative and the negotiated unconscious

This investigation is a practice-based inquiry. It takes place in the context of writing and editing a novel manuscript: The earth does not get fat (Prendergast 2012). The unpublished novel manuscript is a fractured narrative, a tale told in multiple first-person voices. One of the problems the writer encountered, as the novel developed, was a problem from the perspective of logic and continuity: the stories did not fit together in a linear way. As a result, the writer felt estranged from the writing and, at the same time, strangely familiar with it. Despite having produced the narrative, the writer felt that it was ‘other’. This paper summarises the writer's methodology; it explains the writer's attachment to this fractured style of telling. This fractured style is assessed within the context of the mind's ability to produce its effects without full consciousness. The analysis of authorial intention therefore focuses upon the influence of altered states of consciousness upon narrative material. In particular, the writer uses Andreas Mavromatis’ (1987) work on hypnagogia: described as ‘the unique state of consciousness between wakefulness and sleep’ to describe the experience of the operation of the unconscious in authorial intention.

Xenomelia: a social neuroscience view of altered bodily self-consciousness

Xenomelia, the "foreign limb syndrome," is characterized by the non-acceptance of one or more of one's own extremities and the resulting desire for elective limb amputation or paralysis. Formerly labeled "body integrity identity disorder" (BIID), the condition was originally considered a psychological or psychiatric disorder, but a brain-centered Zeitgeist and a rapidly growing interest in the neural underpinnings of bodily self-consciousness has shifted the focus toward dysfunctional central nervous system circuits. The present article outlays both mind-based and brain-based views highlighting their shortcomings. We propose that full insight into what should be conceived a "xenomelia spectrum disorder" will require interpretation of individual symptomatology in a social context. A proper social neuroscience of xenomelia respects the functional neuroanatomy of corporeal awareness, but also acknowledges the brain's plasticity in response to an individual's history, which is lived against a cultural background. This integrated view of xenomelia will promote the subfield of consciousness research concerned with the unity of body and self.

Altered states: Involvement of phosphorylated CagA in the induction of host cellular growth changes by Helicobacter pylori

Helicobacter pylori, present in half of the world’s population, is a very successful pathogen. It can survive for decades in the human stomach with few obvious consequences to the host. However, it is also the cause of gastric diseases ranging from gastritis to ulcers to gastric cancer and has been classified a type 1 carcinogen by the World Health Organization. We have previously shown that phosphorylation of a 145-kDa protein and activation of signal transduction pathways are associated with the attachment of H. pylori to gastric cells. Here we identify the 145-kDa protein as the H. pylori CagA protein. We also show that CagA is necessary to induce a growth-factor-like phenotype (hummingbird) in host gastric cells similar to that induced by hepatocyte growth factor (HGF). Additionally, we identify a second cellular phenotype induced after attachment by H. pylori, which we call SFA (stress fiber associated). SFA is CagA independent and is produced by type I and type II H. pylori.

What affective neuroscience means for science of consciousness

The field of affective neuroscience has emerged from the efforts of Jaak Panksepp in the 1990s and reinforced by the work of, among others, Joseph LeDoux in the 2000s. It is based on the ideas that affective processes are supported by brain structures that appeared earlier in the phylogenetic scale (as the periaqueductal gray area), they run in parallel with cognitive processes, and can influence behaviour independently of cognitive judgements. This kind of approach contrasts with the hegemonic concept of conscious processing in cognitive neurosciences, which is based on the identification of brain circuits responsible for the processing of (cognitive) representations. Within cognitive neurosciences, the frontal lobes are assigned the role of coordinators in maintaining affective states and their emotional expressions under cognitive control. An intermediary view is the Damasio-Bechara Somatic Marker model, which puts cognition under partial somatic-affective control. We present here our efforts to make a synthesis of these views, by proposing the existence of two interacting brain circuits; the first one in charge of cognitive processes and the second mediating feelings about cognitive contents. The coupling of the two circuits promotes an endogenous feedback that supports conscious processes. Within this framework, we present the defence that detailed study of both affective and cognitive processes, their interactions, as well of their respective brain networks, is necessary for a science of consciousness.© MSM 2013.
