On the Emergence of Orientation Biases in V1
Though the site of the emergence of orientation biases in the primary visual cortex (V1) is still debated, it seems that the consensus is converging on the idea originally suggested by Hubel and Wiesel in early 1960’s; the idea that the convergence of spatially-arranged geniculate inputs on single cortical cells is the source of orientation biases in V1. But, is the Hubel–Wiesel type of geniculocortical connectivity is the only choice V1 has to generate orientation biases?
