What Are All Those Neurons in Foveal V1 Doing?

The foveal region of V1 vastly over-represents not just the visual field, but also retinal ganglion cells, in comparison to parafoveal or peripheral V1.   This implies that there are some fairly unique visual computations happening in the fovea that don't happen in other parts of V1, but what these are is still largely unknown.  Here I shall present one hypothesis based on the idea that foveal V1 neurons are super-resolving the information provided by retinal ganglion cells by exploiting the eye's own drift motions.  I shall describe the neural circuitry needed to allow V1 to build a more complete and detailed representation of visual information than is provided statically by the cones.
