This turns out to be the case
wherever in area 17 we record.
In the fovea, the receptive
fields are tiny, and so is the
movement in the visual field
produced by a 2-millimeter
movement along the cortex: in
the periphery, both the
receptive fields and the
movements are much larger, as
illustrated in the figure to the
left.
In a macaque monkey, the
upper-layer receptive fields
grow larger as eccentricity
increases from the fovea (0
degrees). Also growing by an
equal amount is the distance
the receptive fields move in the
visual field when an electrode
moves 2 millimeters along the
cortex parallel to the surface.
