SO3 symmetry breaking mechanism for orientation and spatial frequency tuning in the visual cortex.

چکیده
A dynamical model of orientation and spatial frequency tuning in a cortical hypercolumn is presented. The network topology is taken to be a sphere whose poles correspond to orientation pinwheels associated with high and low spatial frequency domains, respectively. Recurrent interactions within the sphere generate a tuned response via an SO3 symmetry breaking mechanism.

Cortical maps of separable tuning properties predict population responses to complex visual stimuli.
In the earliest cortical stages of visual processing, a scene is represented in different functional domains selective for specific features. Maps of orientation and spatial frequency preference have been described in the primary visual cortex using simple sinusoidal grating stimuli. However, recent imaging experiments suggest that the maps of these two spatial parameters are not sufficient to ...
متن کاملThe visual cortex as a crystal
A theory of pattern formation in primary visual cortex (V1) is presented that takes into account its crystalline-like structure. The cortex is partitioned into fundamental domains or hypercolumns of a lattice describing the distribution of singularities or pinwheels in the orientation preference map. Each hypercolumn is modelled as a network of orientation and spatial frequency selective cells ...
متن کاملTwo symmetry breaking mechanisms for the development of orientation selectivity in a neural system
Orientation selectivity is a remarkable feature of the neurons located in the primary visual cortex. Provided that the visual neurons acquire orientation selectivity through activity-dependent Hebbian learning, the development process could be understood as a kind of symmetry breaking phenomenon in the view of physics. The key mechanisms of the development process are examined here in a neural ...
متن کاملCorrelation of local and global orientation and spatial frequency tuning in macaque V1.
Visual cortical neurones display a variety of visual properties. Among those that emerge in the primary visual cortex V1 are sharpening of selectivity for spatial frequency and for orientation. The selectivity for these stimulus attributes can be measured around the peak of the tuning function, usually as bandwidth. Other selectivity measures take into account the response across a broader rang...
متن کاملThe functional geometry of local and horizontal connections in a model of V1.
A mathematical model of interacting hypercolumns in primary visual cortex (V1) is presented that incorporates details concerning the geometry of local and long-range horizontal connections. Each hypercolumn is modeled as a network of interacting excitatory and inhibitory neural populations with orientation and spatial frequency preferences organized around a pair of pinwheels. The pinwheels are...
