The Brain as a Dream State Generator: An Activation-Synthesis Hypothesis of the Dream Process

Abstract: Recent research in the neurobiology of dreaming sleep provides new evidence for possible structural and functional substrates of formal aspects of the dream process. The data suggest that dreaming sleep is physiologically determined and shaped by a brain stem neuronal mechanism that can be modeled physiologically and mathematically. Formal features of the generator processes with strong implications for dream theory include periodicity and automaticity of forebrain activation, suggesting a preprogrammed neural basis for dream mentation in sleep; intense and sporadic activation of brain stem sensorimotor circuits including reticular, oculomotor, and vestibular neurons, possibly determining spatiotemporal aspects of dream imagery; and shifts in transmitter ratios, possibly accounting for dream amnesia. The authors suggest that the automatically activated forebrain synthesizes the dream by comparing information generated in specific brain stem circuits with information stored in memory.

The relation of eye movements during sleep to dream activity: an objective method for the study of dreaming.

Abstract: The study of dream activity and its relation to physiological variables during sleep necessitates a reliable method of determining with precision when dreaming occurs. This knowledge, in the final analysis, always depends upon the subjective report of the dreamer, but becomes relatively objective if such reports can be significantly related to some physiological phenomena which in turn can be measured by physical techniques. Such a relationship was reported by Aserinsky and Kleitman (1) who observed periods of rapid, conjugate eye movements during sleep and found a high incidence of dream recall in Ss awakened during these periods and a low incidence when awakened at other times. The occurrence of these characteristic eye movements and their relation to dreaming were confirmed in both normal Ss and schizophrenics (4), and they were shown to appear at regular intervals in relation to a cyclic change in the depth of sleep during the night as measured by the EEC (5). This paper represents the results of a rigorous testing of the relation between eye movements and dreaming. Three approaches were used: (a) Dream recall during rapid eye movement or quiescent periods was elicited without direct contact between E and S, thus eliminating the 1 Postdoctoral Public Health Service Research Fellow of the National Institute of Neurological Diseases and Blindness. 2 Aided by a grant from the Wallace C. and Clara A.

The function of dream sleep

Abstract: We propose that the function of dream sleep (more properly rapid-eye movement or REM sleep) is to remove certain undesirable modes of interaction in networks of cells in the cerebral cortex. We postulate that this is done in REM sleep by a reverse learning mechanism (see also p. 158), so that the trace in the brain of the unconscious dream is weakened, rather than strengthened, by the dream.

Sleep, learning, and dreams: off-line memory reprocessing

Abstract: Converging evidence and new research methodologies from across the neurosciences permit the neuroscientific study of the role of sleep in off-line memory reprocessing, as well as the nature and function of dreaming. Evidence supports a role for sleep in the consolidation of an array of learning and memory tasks. In addition, new methodologies allow the experimental manipulation of dream content at sleep onset, permitting an objective and scientific study of this dream formation and a renewed search for the possible functions of dreaming and the biological processes subserving it.

The mind's best work

Abstract: Over the years, tales about the creative process have flourished-tales of sudden insight and superior intelligence and personal eccentricity. Coleridge claimed that he wrote "Kubla Khan" in one sitting after an opium-induced dream. Poe declared that his "Raven" was worked out "with the precision and rigid consequence of a mathematical problem." D. N. Perkins discusses the creative episodes of Beethoven, Mozart, Picasso, and others in this exploration of the creative process in the arts, sciences, and everyday life.
