Pinwheel stability, pattern selection and the geometry of visual space

چکیده
It has been proposed that the dynamical stability of topological defects in the visual cortex re ects the Euclidean symmetry of the visual world. We analyze defect stability and pattern selection in a generalized Swift-Hohenberg model of visual cortical development symmetric under the Euclidean group E(2). Euclidean symmetry strongly in uences the geometry and multistability of model solutions but does not directly impact on defect stability.

Self-organization and the selection of pinwheel density in visual cortical development
Self-organization of neural circuitry is an appealing framework for understanding cortical development, yet its applicability remains unconfirmed. Models for the self-organization of neural circuits have been proposed, but experimentally testable predictions of these models have been less clear. The visual cortex contains a large number of topological point defects, called pinwheels, which are ...

متن کاملArrangement of orientation pinwheel centers around area 17/18 transition zone in cat visual cortex.
In the primary visual cortex of higher mammals, orientation preferences are represented continuously except for singular points, so-called pinwheel centers. In spite of the uniqueness of orientation pinwheel centers, very little is known about the pattern of their arrangement. In this study we examined the arrangement of orientation pinwheel centers in the cat visual cortex by optical imaging o...
