摘要：

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 SO(3) symmetry breaking mechanism.
