Primary visual cortex has become a model system for neuronal processing by the circuitry of the cerebral cortex. Ultimately, we would like to understand how the higher cortical areas give rise to our recognition of sensory stimuli, decision making, and language comprehension. But, we barely have a way of defining what tasks are performed in these areas, let alone how they are performed. By comparison, the transformations performed by the primary visual cortex on its thalamic inputs – the extraction of orientation and direction information, for example – are complex enough to be interesting, but simple enough to be tractable. The neuronal mechanisms by which cortical receptive properties emerge have therefore become the subject of intense scrutiny and debate.
