Dynamic Coordination in the Brain

The MIT Press

This chapter examines dynamic coordination in Gestalt perception by focusing on the problem of accumulating local errors and the trade-off between spatial and temporal resolution in pictorial representations. It illustrates the first issue by using an old and wonderful architectural mystery, the enigma of the Florence Dome, and the second issue using the history of photography. The solutions to both problems are based on global geometry. The two classic examples are accompanied by visual phenomena showing the relevance of symmetry-based representations in the dynamic coordination of visual perception. The chapter also looks at the unsolved problem of segmentation in vision, contrast sensitivity maps and image compression in the visual cortex, and how synchronous firing of orientation-tuned neurons mediates the compression and provides “hot-spots” in the neural representation of the segmented visual input.

Keywords:   dynamic coordination, Gestalt perception, local errors, pictorial representations, geometry, visual perception, segmentation, image compression, visual cortex, hot-spots
