Different ocular dominance map formation by influence of orientation columns in visual cortices
نویسندگان
چکیده
In animal experiments, the observed orientation preference (OP) and ocular dominance (OD) columns in the visual cortex of the brain show various pattern types. Here, we show that the different visual map formations in various species are due to the crossover behavior in anisotropic systems composed of orientational and scalar components such as easy-plane Heisenberg models. We predict the transition boundary between different pattern types with the anisotropy as a main bifurcation parameter, which is consistent with experimental observations.

Receptive Fields and Maps in the Visual Cortex: Models of Ocular Dominance and Orientation Columns
under the title \Models of Ocular Dominance and Orientation Columns." Reused by permission. ABSTRACT The formation of ocular dominance and orientation columns in the mammalian visual cortex is brieey reviewed. Correlation-based models for their development are then discussed, beginning with the models of Von der Malsburg. For the case of semi-linear models, model behavior is well understood: co...
متن کاملThe influence of restricted orientation rearing on map structure in primary visual cortex
Visual experience is critical to the development of the structure of the primary visual cortex and, in turn, normal functional vision. The primary visual cortex contains maps of multiple features of the visual input, and these maps are characterised by specific types of geometric relationships. Manipulations of the visual environment during development in animals such as ferrets, cats and monke...
متن کاملThe layout of orientation and ocular dominance domains in area 17 of strabismic cats.
In the primary visual cortex of strabismic cats, the elimination of correlated activity between the two eyes enhances the segregation of the geniculocortical afferents into alternating ocular dominance domains. In addition, both tangential intracortical fibres and neuronal synchronization are severely reduced between neurons activated by different eyes. Consequently, ocular dominance columns be...
متن کاملDevelopment of Orientation and Ocular Dominance Columns in Infant Macaques
Maps of orientation preference and ocular dominance were recorded optically from the cortices of 5 infant macaque monkeys, ranging in age from 3.5 to 14 weeks. In agreement with previous observations, we found that basic features of orientation and ocular dominance maps, as well as correlations between them, are present and robust by 3.5 weeks of age. We did observe changes in the strength of o...
متن کاملUnderstanding visual map formation through vortex dynamics of spin Hamiltonian models.
The pattern formation in orientation and ocular dominance columns is one of the most investigated problems in the brain. From a known cortical structure, we build spinlike Hamiltonian models with long-range interactions of the Mexican hat type. These Hamiltonian models allow a coherent interpretation of the diverse phenomena in the visual map formation with the help of relaxation dynamics of sp...
