BOLD_G Model of the Brain: A Green Flow Metaphor by Margarete Jahrmann and Stefan Glasauer:

Presented at Medical Museion Copenhagen, Theatrum Anatomicum at the occasion of the

12th Conference of the European Society for Literature, Science and the Arts (SLSAeu)


In BOLD_G Model we understand brain activity as flow of biochemical substances, similar to the flow of blood — instead
of electromechanically influencedmetaphors about the “firing” of neurons, “spikes” and “action potentials”. The flow metaphor allows moving away from misleading notions such as “the brain as a computer” and provides a more natural view on the central ner- vous system. In the BOLD_G model brain function can be un- derstood as flow, diffusion and absorption, an exchange of liquids and solvents. The flow model of the brain is a green metaphor, much more akin to the vascular transport of nutrients in plants. The flow metaphor is obvious also in current measurement tech- niques of brain function such as blood oxygen level dependent (BOLD) contrast imaging or calcium imaging. The green blood in censored games reminds us of these interconnections — of the bloodstream and data as its constituent element. In a structural coupling of contents and fields of research as enacted Ludic met- hod we perform the song of the neurons and visualize our model by animating the epistemic object, the neuron, appearing as green stream of thought and its representations.

panteonMargarete Jahrmann works in artistic research and critical game activism, focusing on experimental systems as hermeneu- tical surface. Stemming from a decade of experience in game art exhibitions, Augmented Reality performances, game design and game culture publications, she intensified her focus on arts experience: a temporary refugium research in life sciences and neurophilosophy. With her latest art works and articles she critically questions scientific experiments in relation to the recent increase of brain reading practices, self-optimization and data surveillance in gamified life style technologies.

ExperimentCopenhagenStefan Glasauer is a neuroscientist, Professor for Computational Neurosciences at University Cottbus, teaching and working at the Ludwig-Maximilians-University Munich. He is interested in general principles underlying perception, action, and sensori- motor control. After studying Electrical Engineering with a focus in cybernetics, he did his PhD at the Max-Planck-Institute for Behavioral Physiology on perception of gravity.
