Abstract\n\n“Royal road to the unconscious” as considered by Dr. Sigmund Freud during his dream analysis in 1900 gives a good start to the philosophers when it comes to satisfy their theories in psychophysiological manner. During the early stages of human evolution, there have always been physical and materialistic needs that were to be fulfilled as a necessity of survival. Dreams on the...
This article explores the notion that the brain is genetically endowed with an innate virtual reality generator that - through experience-dependent plasticity - becomes a generative or predictive model of the world. This model, which is most clearly revealed in rapid eye movement (REM) sleep dreaming, may provide the theater for conscious experience. Functional neuroimaging evidence for brain...
Recent findings link fronto-temporal gamma electroencephalographic (EEG) activity to conscious awareness in dreams, but a causal relationship has not yet been established. We found that current stimulation in the lower gamma band during REM sleep influences ongoing brain activity and induces self-reflective awareness in dreams. Other stimulation frequencies were not effective, suggesting that...
Consciousness is defined and a relation is established between its altered states of consciousness (ASC) and as well to the ways how they are provoked. Phenomenology of ASC is described and related to psychopathology. A short commentary is made about ASC used in some ethnopsychotherapy. Psychotherapy, of western origin, using ASC, specially hypnosis, directed day-dream (reve eleille dirige) of...

Neurophysiological and neuroimaging studies including both patients with disorders of consciousness and healthy subjects with modified states of consciousness suggest a crucial role of the medial posteroparietal cortex in conscious information processing. However no direct neuropsychological evidence supports this hypothesis and studies including patients with restricted lesions of this brain...
Converging evidence suggests that dreaming is influenced by the consolidation of memory during sleep. Following encoding, recently formed memory traces are gradually stabilized and reorganized into a more permanent form of long-term storage. Sleep provides an optimal neurophysiological state to facilitate this process, allowing memory networks to be repeatedly reactivated in the absence of new...
Dreaming is an important state of consciousness that complements the awake state. Self-awareness, as well as the ability to recognize other people, are essential characteristics of everyday life. The recognition of Self and others is based on, among others, autobiographical and episodic memory, and emotional, and evaluative systems, or perceptual cues. The goal of the paper is to answer a...
This article explores transcendental experiences during meditation practice and the integration of transcendental experiences and the unfolding of higher states of consciousness with waking, dreaming, and sleeping. The subject/object relationship during transcendental experiences is characterized by the absence of time, space, and body sense--the framework that gives meaning to waking...
We normally assess another individual's level of consciousness based on her or his ability to interact with the surrounding environment and communicate. Usually, if we observe purposeful behavior, appropriate responses to sensory inputs, and, above all, appropriate answers to questions, we can be reasonably sure that the person is conscious. However, we know that consciousness can be entirely...
