Abstract There is now abundant evidence that the structure of the mammalian visual cortex is not innately determined but can be altered by visual experiences during a certain period at an early age. A model based on the evidence is proposed that will explain some aspects of the developmental process in the visual cortex. The model self-organizingly forms “a simple cell” which responds to bars and edges of a certains orientation and retinal position. The total system of the model corresponds to “a hyper column” which contains a complete cycle of orientational selectiviy. The model has the following three original points. i) “A hyper column” is finally formed in the model. ii) Most of the cells do not have orientation selectivity in the initial state. iii) It is hypothesized that the orientation continuity of the hyper column is caused by similar orientations of successive input stimuli. The results of computer simulation show that the model has the expected performance.
