Research Areas

The Perceptual Dynamics Laboratory takes a "complex systems" approach to visual information processing. Complex systems are dynamical systems with large numbers of degrees of freedom. Their dynamics is characterized by spatio-temporal intermittency, chaotic itinerancy, and self-organized criticality. The aim of the laboratory is two-fold: to develop models of the human visuo-perceptual system based on the complex systems approach and to test the assumptions of these models in laboratory experiments. Accordingly, the laboratory consists of a multi-disciplinary team of scientists, reflecting on a small scale the multi-disciplinary character of BSI.



Research Subjects

  1. Basic visual processing functions
  2. Complex visual functions
  3. Self-organization of functional brain architecture
