Brain activity when dreams take place, is similar to an awakened state, except for the thalamus, an ancient phylogenetic structure in the nervous system, insulates the brain activity from the environment, desensitizing the dreamer to noise and impeding, for instance, walking, if the dream involves walking.
However, the insulation is not total and external stimuli sometimes filter into what is happening in dreams. In order to establish a bridge between the EEG chart and the narrative of dreams, Nathalie experiment with the possibility of interfering her dreams by the way of external stimuli; sounds made while she sleeps. During 80 days Nathalie charts her brain's electrical activity when dreaming. Roberto developed a computer program, called InDreams, to produce simple, short auditory stimulus, –for example, her own name or those of close acquaintances–, which might induce autobiographical memories to mix into the dream narrative.
Every time the stimulus becomes part of her dream narrative, an a posteriori correspondence was established between the EEG chart analysis and the narrative. We choose one example and represent it in a work that demonstrate the convergence of these two points of view: the objective EEG registry against the subjective narrative.
We visualize the analysis of each dream as a three-dimensional texture for instance, the resulting spectral analysis of the EEG reading, or the amplitude of electrical force– we registered in bas-relief on cardboard, the milling computer-controlled or digital-laser drafted. Alongside with this analysis, the laser drafter recorded her dream narrative, precisely showing where the objective and subjective viewpoints coincide.
Thus, each piece will evince the points of correspondence—but mostly the distance—between the EEG chart analysis that allows today’s science to know she's dreaming and her subjective experience of it.
For a 2010 series of talks on cognitive experiences in the realm of art, Mario Borillo wrote in an introduction that, “The universe of art is the supreme site for mental activity for both the creator and the spectator. An activity whose distinguishing mark appears to be the space given over to the imagination, to dreams, to memory, to passions, to subjectivity’s flows. This universe, heretofore obdurate or inaccessible to the exigencies of scientific analysis, is beginning to make its way into the cognitive science study field.”
During the creative process, an artist must above all inquire into the subjective experience of perception and—more or less consciously—ask in what ways it enables the construction of our relationship with the world. As Mario Borillo suggests, the study of this process situated at the physical-mental node is a task befitting the neuroscientist.
Global Mind Project in Melbourne, Australia, is a multidisciplinary initiative that delves into consciousness and creativity by means of an interface between Emotiv EPOC EEG technology and software, which renders audio-visuals from neural data, going beyond the usual video art to become a real-time (performance) operating system. In 2010, Global Mind Project presented “The Spectacle of the Mind,” with the participation of Australian performance artists Stelarc, Domenico de Clario and Jill Orr.
This interest in the subjective experience as pure neurobiological phenomenon was also the topic of a symposium held in Venice in June 2011, which was organized by the Association of Neuroesthetics Berlin for the Peggy Guggenheim Collection and the Marino Golinelli Foundation. There, artist Ivana Franke in collaboration with neuroscientist Ida Momennejad presented “Seeing with Eyes Closed,” inviting the public to enter into the piece by sitting in front of a strobe light for six minutes with eyes closed. The experience is almost hallucinatory, with participants perceiving colorful moving shapes; images that are not situated on a screen nor properly in the mind, either. In reality, they are produced by the interaction between the body and the light stimulus. What is perceived depends on the individual, hence, the experience remains invisible, impossible to depict.
Inquiry into the effective content of the subjective experience of dreaming – the most ancient aesthetic activity, as Jorge Luis Borges concludes in his talk “The Nightmare”– is our project’s principal contribution to the field of art. The project aims to overcome the barriers preventing the display of the invisible subjective experience by utilizing the dreaming body to aid exterior observation.
For the last 22 years Nathalie has been assiduously writing down her dreams, a daily exercise that has steadily increased her capacity to remember them. In the same way she describes her dreams sans-interpretation–, she submited herself to analysis by the apparatus, thus to confront the production of mental images rendered in writing with the images of mind activity obtained with the Emotiv EPOC EEG in order to explore for meaning at the nexus between the two representations.
The work seeks to insightfully confront what the machine reveals on its chart and what the narration of the dream reveals in its telling. These two accounts eventually end up corroborating each other, thereby furnishing an enriched description of what is happening in the brain at the moment a new image emerges.
In addition to the artistic uses, the 80-Days-In-Dreams Project experiment into the nexus between the subjective and objective factors of dreams aims to go public with the findings, making them available to the scientific community.
The Depicting 80 Days-in-Dreams Project is designed to observe dreams and attempt to stimulate them with a simple auditory device. Central to the study is the concordance between two apparently divergent means of displaying or depicting the dream experience during 80 consecutive days.
Four registries come from this experience, which are:
• An EEG chart and its analysis.
• A diary that narrates her memories of the dreams which scrutinizes whether the stimulus applied during her dream state filtered into what took place in the dream, and more specifically, whether it is reflected in her diary account.
• A personal diary that succinctly and precisely gives an account of her daily activities.
• Two prototypes for the design of the bas-reliefs, showing instants in which the dream plot and the reading of the EEG device establish a bridge.
• One bas-reliefs depicting the instance when the computer-produced auditory stimulus became incorporated into the dream plot.
Marcia Tucker, in writing about Bruce Nauman, describes our awareness of the world as, “the sum of our perceptions and of our physical, emotional and intellectual responses to our surroundings” (Art Forum 9 no. 4, New York, December 1970). In submitting her awareness of dreams to this experience, let her open herself to a new territory of observation.
The 80 Days-In-Dreams archive including the bas-reliefs was premièred in June 2014 at the Brain Art Exhibition of the annual international conference of the Human Brain Mapping organisation at CCH - Congress Center Hamburg, in Hamburg, Germany.
