Abstract
Within individual penetrations in the cat visual cortex, spatial periodicities of periodic complex cells differ by 1/2 or 1 octave. Pooled data fron neurons subserving the central visual area in many cats, indicated that spatial periodicities cluster at 1/2 octave intervals over a 2 1/2-octave range (0.95-5.4 cycle/deg). A relatively small number of cuch channels spaced at regular intervals along a logarithmic scale within each orientation column may suffice for this stage of spatial processing.
