The Brain's view of the natural world in motion

The basic idea (leading to a definite model) is that neurons and neural systems can analyze the visual field in Fourier space to carry out motion contrast detection and estimation. This idea for neural implementation of the computations involved in motion analysis provides an interesting biological counterpart to the notion, formalized in quantum mechanics, that position (spatial location) and momentum (motion) are equally fundamental dual aspects of natural phenomena.
