Book excerpt: As the title (Genesis XLI :18) of the book indicates, interest in dreams goes back at least to Biblical times. It persisted during subsequent years to peak in the 20th century following publication of Sigmund Freud’s major work “The Interpretation of Dreams”. Freud was concerned with the psychology of dreams perhaps because biological science of that era was not ready to provide physiological explanation of the purpose of dreams. Much neuroscience has been discovered in the century since Freud to permit a new view of sleep and dreams. A great deal has been learned about the “what “of sleep: its stages, electrographic accompaniment, eye movements, muscle atonia and behavioral manifestations. There are ideas about the “why” of sleep: restorative processes, protein synthesis, secretion of growth hormone, clearing of adenosine, immunologic enhancement and consolidation of memory. Only a little is known of the “what” of dreams: cerebral areas that are activated and deactivated on imaging studies, cerebral lesions that cause loss of dreaming and a bit about ontogenesis. The “why” of dreams remains uncertain. In this brief monograph, Dr. Locke offers a bold new hypothesis about the purpose of the dream. Following chapters on sleep, memory and the structure of the dream he suggests that one function of sleep and dreams is to establish neurological cellular networks to accept new memories. The muscle atonia of REM sleep deactivates neural networks in motor cortex, cerebellum and basal ganglia to allow them to accept new motor algorithms of procedural memory. The structure of the transient and preparatory dream – its narrative and imagery – is selected during REM sleep by a largely inhibited hippocampus that permits only incomplete retrieval of neural assemblies accounting for the distortion, condensation, fusion and confusion of the dream. New neural assemblies are activated in parietal cortex by dreams that are promptly forgotten to allow the unoccupied network, held in readiness by snaptic tags, to accept new declarative memories in the waking state of the new day.
