Frequency Space Evolution of Pattern Forming Systems
These videos were rendered as part of the research for the paper "A Model for the Origin and Properties of Flicker-Induced Geometric Phosphenes". In this work, we showed how periodic stimulation (a uniform flickering light) could lead to emergence of geometric patterns in the brain's visual system. The videos below show the evolution of these patterns in the Fourier domain (spatial frequency space).
