  • For each recording site, we tabulate the fraction of spike trains that had power ratios outside the SMRP range. We also tabulate the fraction of cells that fired such non-SMRP spike trains in response to drifting–grating stimuli of a wide range of contrasts, most of which were below 40%, and also in response to stimuli of high contrast (>40%) alone.
