Model for Human Visual Processing Which Explains Perceptions of Motion-After-Effects.

摘要

A theoretical model for human visual information processing was developed which attributes functional roles to the cerebellum, lateral geniculate nucleus, and cerebral cortex. The lateral geniculate nucleus is believed to provide sequential monocular mappings as inputs to the primary visual cortex, which uses this information for binocular integration, detection of motion, and other of its functions. In an experiment with the limits of human binocular fusion, two separate limits were discovered. When dichoptic images are first perceived to represent a single object, the limit for fusion is greater than when no initial reference for a single object association is given. A second experiment measured the stimulus duration thresholds for motion-after-effects. Correlation of performance by subjects in the two experiments was used to conclude that similar mechanisms are involved in binocular fusion and the processing of perceptions leading to motion-after-effects.
