title: Neural mechanisms for the generation of visual complex cells.
abstract: In 1962, Hubel and Wiesel reported what they later described as "the first description of a clear function for the cerebral cortex, in terms of clear differences between input and output". Martinez and Alonso (2001[this issue of Neuron]) now provide evidence for the hierarchical neural circuit that Hubel and Wiesel proposed to explain the cortical transformation from simple to complex cells.
