“…In order to get the best correlates between psychological data (subjects' reports) and physiological data (polysomnography), the data set was split into various 7.5 second epochs. Discriminant function analysis, MANOVA, and ANOVA revealed that the main factor discriminating lucid from non lucid dreams was the beta-1frequency band, which signifi cantly increased during lucid dreaming in the parietal regions of both hemispheres, which is in opposition to the results previously obtained by Ogilvie et al (1978) and Ogilvie et al (1982). The ratio of frontal to parietal beta-1 activity was 1 to 1.16 during non-lucid dreaming and 1 to 1.77 during lucid dreaming.…”

Although the concept of 'lucid dreaming' was fi rst coined by Frederik Willems van Eeden, a Dutch psychiatrist, and introduced at the meeting of The Society for Psychical Research held on 22 April 1913, the phenomenon of lucid dreaming was already known in earlier historical periods and its descriptions can be found in writings of Aristotle. However, modern lucid dreaming research was established only after LaBerge introduced his method for physiological investigation of lucid dreaming through eye signals in 1980. Current attempts in the fi eld are directed at defi ning the neuro-physiological correlates of lucid dreaming, an aim that still has yet to be achieved. One of the possible applications of lucid dreaming is in the fi eld of psychotherapy where it is usually used in treating nightmares. However, other possible therapeutic potentials of lucid dreaming are still in the process of being discovered and therefore constitute a fertile area for future researchers.

“…Although it is an interesting idea to associate dream lucidity with alpha activity in the EEG during REM sleep, this causality of this relation seems to be unclear (cf. Ogilvie et al, 1983;Ogilvie et al, 1982) and a possibility of using such biofeedback is a rather complicated method for lucid dream induction.…”

In lucid dreams the dreamer is aware of dreaming and often able to influence the ongoing dream content. Lucid dreaming is a learnable skill and a variety of techniques is suggested for lucid dreaming induction. This systematic review evaluated the evidence for the effectiveness of induction techniques. A comprehensive literature search was carried out in biomedical databases and specific resources. Thirty-five studies were included in the analysis (11 sleep laboratory and 24 field studies), of which 26 employed cognitive techniques, 11 external stimulation and one drug application. The methodological quality of the included studies was relatively low. None of the induction techniques were verified to induce lucid dreams reliably and consistently, although some of them look promising. On the basis of the reviewed studies, a taxonomy of lucid dream induction methods is presented. Several methodological issues pertaining to both studies reviewed and lucid dream induction research in general are discussed.

“…Freud famously said of dreams that they provide privileged access to the workings of the unconscious mind (Freud, 1937) but research on dreaming is fraught with difficulties because [despite the phenomenon of lucid dreaming (Ogilvie et al, 1982)] the dream experience cannot be easily reflected on and reported in real-time, and neither can its onset and offset be easily controlled. Thus, Freud's cherished “royal road” has not proved particularly regal and a more practical alternative is required if key psychoanalytic theories are to be incorporated into the mind sciences.…”

Entropy is a dimensionless quantity that is used for measuring uncertainty about the state of a system but it can also imply physical qualities, where high entropy is synonymous with high disorder. Entropy is applied here in the context of states of consciousness and their associated neurodynamics, with a particular focus on the psychedelic state. The psychedelic state is considered an exemplar of a primitive or primary state of consciousness that preceded the development of modern, adult, human, normal waking consciousness. Based on neuroimaging data with psilocybin, a classic psychedelic drug, it is argued that the defining feature of “primary states” is elevated entropy in certain aspects of brain function, such as the repertoire of functional connectivity motifs that form and fragment across time. Indeed, since there is a greater repertoire of connectivity motifs in the psychedelic state than in normal waking consciousness, this implies that primary states may exhibit “criticality,” i.e., the property of being poised at a “critical” point in a transition zone between order and disorder where certain phenomena such as power-law scaling appear. Moreover, if primary states are critical, then this suggests that entropy is suppressed in normal waking consciousness, meaning that the brain operates just below criticality. It is argued that this entropy suppression furnishes normal waking consciousness with a constrained quality and associated metacognitive functions, including reality-testing and self-awareness. It is also proposed that entry into primary states depends on a collapse of the normally highly organized activity within the default-mode network (DMN) and a decoupling between the DMN and the medial temporal lobes (which are normally significantly coupled). These hypotheses can be tested by examining brain activity and associated cognition in other candidate primary states such as rapid eye movement (REM) sleep and early psychosis and comparing these with non-primary states such as normal waking consciousness and the anaesthetized state.
