    SOM-Model for the development of oriented receptive fields and orientation maps from non-oriented ON-center OFF-center inputs

    We investigate the development of oriented receptive fields and an orientation map in a SOM-model which is driven by rotationally symmetric stimuli in ON-center and OFF-center input layers. To this end we use ...

    Geometry of orientation preference map determines nonclassical receptive field properties

    We propose a simple mechanism for the nonclassical receptive field property of orientation contrast sensitivity. Our model includes the long-range lateral connections linking cell populations of similar orient...

    Precise restoration of cortical orientation maps explained by hebbian dynamics of geniculocortical connections

    It is widely assumed that experience dependence and variability of the individual layout of cortical columns are the hallmarks of activity-dependent self-organization during development. Recent optical imaging...
