Modeling Joint Development of Ocular Dominance and Orientation Maps in Primary Visual Cortex
نویسندگان
چکیده
We have combined earlier correlation-based models of striate ocular dominance and orientation preference map formation into a joint model. Cortical feature preferences are deened through patterns of synaptic connectivity to LGN cells which develop due to ring correlations of those LGN cells. Model parameters include spatial correlation patterns between ON-and OFF-center cells in separate eye layers of the LGN. A linear transformation yields correlation functions which predict whether orientation preferences, ocular dominance, or both, will develop. The model thus predicts the correlations between LGN cells which would be necessary to explain formation of visual maps by a linear process.

The 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 کاملOcular dominance peaks at pinwheel center singularities of the orientation map in cat visual cortex.
In the primary visual cortex of monkey and cat, ocular dominance and orientation are represented continuously and simultaneously, so that most neighboring neurons respond optimally to visual stimulation of the same eye and orientation. Maps of stimulus orientation are punctuated by singularities referred to as "pinwheel centers," around which all orientations are represented. Given that the ori...
متن کاملPrinciples underlying the development and organization of feature maps in the visual cortex
A fundamental question in neuroscience is how sensory information is represented in the brain. In particular, what principles guide the spatial organization of neurons with regard to their receptive field properties, and how is this organization established mechanistically? The visual cortex serves as a model area to address these questions, but whether general principles can explain the layout...
متن کاملInfluence of lateral connections on the structure of cortical maps.
Maps of ocular dominance and orientation in primary visual cortex have a highly characteristic structure. The factors that determine this structure are still largely unknown. In particular, it is unclear how short-range excitatory and inhibitory connections between nearby neurons influence structure both within and between maps. Using a generalized version of a well-known computational model of...
