Pinwheel stabilization by ocular dominance segregation.
نویسندگان
چکیده
We present an analytical approach for studying the coupled development of ocular dominance and orientation preference columns. Using this approach we demonstrate that ocular dominance segregation can induce the stabilization and even the production of pinwheels by their crystallization in two types of periodic lattices. Pinwheel crystallization depends on the overall dominance of one eye over the other, a condition that is fulfilled during early cortical development. Increasing the strength of intermap coupling induces a transition from pinwheel-free stripe solutions to intermediate and high pinwheel density states.

The 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 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 کاملOrigins of feature selectivities and maps in the mammalian primary visual cortex
A common feature of the mammalian striate cortex is the arrangement of 'orientation domains' containing neurons preferring similar stimulus orientations. They are arranged as spokes of a pinwheel that converge at singularities known as 'pinwheel centers'. We propose that a cortical network of feedforward and intracortical lateral connections elaborates a full set of optimum orientations from ge...
متن کاملSimulated Optical Imaging of Orientation Preference in a Model of V1
Optical imaging studies have played an important role in mapping the orientation selectivity and ocular dominance of neurons across an extended area of primary visual cortex (V1). Such studies have produced images with a more or less smooth and regular spatial distribution of relevant neuronal response properties. This is in spite of the fact that results from electrophysiological recordings, t...
متن کاملRelationship between the Ocular Dominance and Orientation Maps in Visual Cortex of Monocularly Deprived Cats
The significance of functional maps for cortical plasticity was investigated by imaging of intrinsic optical signals together with single-unit recording in kittens. After even a brief period of monocular deprivation during the height of the critical period, only isolated patches of visual cortex continued to respond strongly to the closed eye. These deprived-eye patches were located on the pinw...
