ABSTRACT Kuffler1 described the receptive fields of cat retinal ganglion cells as having a concentric arrangement. This has usually been taken to mean that they are approximately circular in

form (see, for example, ref. 2). Hammond3 tested the circularity of the centre component of receptive fields by plotting a contour of isosensitivity to a small flashed spot. He concluded

that centres were often elliptical (average ratio of major to minor axis 1.23) and that more than 50% of the recorded cells had the major axis oriented within ±20° of the horizontal. Such

data are important for discussions4 of the neurophysiological basis of the ‘Oblique effect’ (reduced visibility for periodic grating patterns when oriented away from the vertical or

since they reveal a previously unsuspected systematic relation between orientation bias of ganglion cells and their location relative to the area centralis. Access through your institution
