Dreaming and the brain: from phenomenology to neurophysiology. Trends in Cognitive Sciences. Lucid dreaming: discontinuity or continuity in consciousness? The notions of continuity and discontinuity are discussed in relation to the phenomenon of lucid dreaming awareness of dreaming while dreaming.

Lucid dreams seem to be more dreamlike than non-lucid … Expand. This article presents evidence in support of the theory that dreaming is imaginative play in sleep.

Detailed visuomotor and other sense modality information that constitutes the representational structure of awareness. Such awareness must involve the interaction and integration of emotion.

Subjective awareness including perception and emotion that is enriched by abstract analysis thinking and metacognitive components of consciousness awareness of awareness. Sleep with electroencephalographic evidence of brain activation similar to that of waking but with inhibition of muscle tone as measured by electromyography and involuntary saccadic eye movements the REMs. A brain state associated with electroencephalographic activation similar to that of REM but with the muscle tone enhancement as measured by electromyography that is necessary for posture and movement.

Sleep with electroencephalographic evidence of brain deactivation; spindles and slow waves characterize this brain state. A science of consciousness must explain how so many aspects of our experience are integrated. The binding of perception, emotion, thought and memory requires a physical explanation at the level of brain function. A primordial state of brain organization that is a building block for consciousness. In humans, protoconsciousness is proposed to develop as brain development proceeds in REM sleep in utero and in early life.

In behavioural neurobiology and cognitive science, the term activation is used to express the level of energy of the brain and its constituent circuits. The analogy to a power supply with an on—off switch conveys the essence of this idea. The process that facilitates or inhibits, as the brain changes state, access to the brain of sensory information input from the outside world and the transmittal of motor commands from the brain output to the musculature.

The chemical microclimate of the brain is determined largely by neurons in the brainstem, which send their axons widely to the forebrain, spinal cord and cerebellum. Among the chemicals released by these cells are dopamine, noradrenaline, serotonin, histamine and acetylcholine. Reprints and Permissions.

Key Points We know how, but not why, the brain is activated in sleep. Abstract Dreaming has fascinated and mystified humankind for ages: the bizarre and evanescent qualities of dreams have invited boundless speculation about their origin, meaning and purpose.
