|CRITICALITY OF THE BRAIN AND CRITICALITY OF THE ART|
Subject(s): CX.02, CX.41
Category: Brief Article
Theory of complex system revealed that the brain is acting close to instability point and therefore human brain can respond to any small perturbation, whether intrinsic or extrinsic. This paper aims to show that the art as a complex system also operates near critical point. Using different notions of instability, borrowed from natural sciences (Lyapunov, Nash, etc.), it will be shown that great many artworks, including well-known masterpieces, exist near unstable points. For instance, balance - the most important principle of compositional design in painting - means creation of instability. The presence of long-range correlations in human writing, painting, and music also indicate that appropriate works of art are at critical point. The relationship between "arousal potential" of artworks and "hedonic value", well known as the Wundt curve (which looks like inverse U) is explained using Ginzburg-Landau theory of phase transition. The "arousal potential" in this model is the order parameter and "hedonic value" plays the role of control parameter. It is easy to show that amount of mutual information processing between the artwork and the brain riches a maximum magnitude when both the artwork and the brain are at critical states. The main conclusion of this paper: the art might be considered as a tool for supporting human brain at critical state.
