the resolving ability of tonic , spectrally opponent ganglion cells was usually similar to that of phasic , non-opponent ganglion cells at similar eccentricities , except that at eccentricities greater than 10 deg some tonic ganglion cells with remarkably high resolution ( up to ca . 15 cycles/deg ) were found .
