Topological Shape Changes Weaken the Innate Defensive Response to Visual Threat in Mice

Understanding the primitives of visual perception is a fundamental question in the study of vision. To address this question, a theory of topology-based functional hierarchy in visual perception has been proposed [1, 2]. This theory suggests that the extraction of topological properties (TPs) serves as the starting point of object perception. The TP of a figure is the holistic identity which remains constant across various smooth shape-changing transformations of an image . For example, the shape of a rubber sheet can be changed through bending and twisting without changing its TP as long as the sheet does not tear. The number of holes in a geometrical object is a TP because it is retained during such rubber-sheet deformations. Thus the TP of an object is thought to be a basic attribute that is crucial for the stability of perception from variable visual input and is processed with priority during visual perception . The “early topological perception” hypothesis was...
