Abstract:Simple cells in the visual cortex process spatial as well as temporal information of the visual stream and enable the perception of motion information. Previous work suggests that the direction selectivity of V1 simple cells is associated with a temporal offset in the thalamocortical input stream through lagged and non-lagged cells of the lateral geniculate nucleus (LGN), but also with intercortical inhibition. While there exists a large corpus of models for spatiotemporal receptive fields, the majority of the… Show more
