Sounds of Complexity

Sounds of Complexity is an artistic project that moves from the field of cognitive science and neurosciences. It's an audiovisual performance in which the sound materials and the visual mappings are the consequence of very complex and stratified processes that hardly can be represented with symbolic forms in our world. It's an attempt to make audible and visible the dynamics and the interactions that for their richness, variety and complexity are unheard and invisible. The audio material of the performance derives from the analogic recording of cerebral activities through an analogic elettroencephalograph (EEG) and corresponds to the discharges of billions of neurons situated in the sixth layer of human cerebral cortex, disposed vertically respect to the scalp. The crude sound of brain is translated in an audible frequencies through techniques of pitch shifting; such material is then processed digitally in real time and the corresponding frequencies transformed in a Cartesian space to form visual trajectories projected on three screens that react dynamically.
