The Limits of Dream focuses on what we currently know of the human central nervous system (CNS), examining the basic sciences of neurochemisty, neuroanatomy, and CNS electrophysiology as these sciences apply to dream, then reaching beyond basic science to examine the cognitive science of dreaming including the processes of memory, the perceptual interface, and visual imagery. Building on what is known of intrapersonal CNS processing, the book steps outside the physical body to explore artificially created dreams and their use in filmmaking, art and story, as well as the role of dreaming in creative process and creative 'madness' The limits of our scientific knowledge of dream frame this window that can be used to explore the border between body and mind. What is known scientifically of the cognitive process of dreaming will lead the neuroscientist, the student of cognitive science, and the general reader down different paths than expected into an exploration of the fuzzy and complex horizon between mind and brain.

presence or absence of dream recall has been studied in human patients with CNS damage (Solms, 1997; Solms & Turnbull, 2002). REM sleep is a brain stem phenomenon. In cats brain stem lesions can be induced that eliminate REM sleep. 32 The Biological Substrate of Dream In humans, it is unusual for patients with extensive brain stem damage to survive that trauma or be able to interact to describe whether they still dream. However, in Solms’ case series of more than 40 patients with extensive

it begins to stir, we have not succeeded in establishing the foetal state of rest” (1917). Freud’s postulate was that dreams functioned as guardians of sleep, getting rid of potential disturbances that could interfere with the organism’s attempt to attain restorative levels of dreamless sleep. In the physiology laboratory, it has been difficult to show restorative effects for either dreamless or dreaming sleep on neurochemical or other metabolic systems. REMS deprivation can affect incorporation

senses. Perception effects memory, and memories can be altered at the level of perception. Dreaming does not generally incorporate perceptual input. Dreams are occurring during sleep, a state of minimal to non-existent perceptual input, and dreams cannot be easily altered by perception. Outside environmental noxious input such as loud noise, pain, and pressure is sometimes incorporated into dreaming in sleep stages that are closer to wake such as sleep onset and rapid eye movement (REM) sleep

another among the several unproven but potential functions for the CNS electrophysiologic rhythms (Chapter 6). By focusing our attention in imagery we can augment images, mentally drawing a location-based image through focused associations. For example, visualize the trunk of your car packed for a trip. We can shift our attention through such an image to look under and behind the bag of food on top, inside the suitcase to examine what we have packed. We inspect the objects in our images using

Cognitive Organization of Dreaming of experience shared by all dreamers. The filmmaker can attempt to incorporate the dreamer’s complete credulity for images with an autonomous power that appear without volition on the part of the dreamer. There is the potential through film to assess the power of a simple dream image to provoke the extreme emotion and the helplessness of the dreamer faced with his own creation (States, 1993). Freudian approaches to criticism utilize the text to achieve a
