Comparison of neurons with Fano factor increasing versus decreasing with contrasta
| Full-contrast Fano | Spontaneous Fano | Rmax | ϵ | αN | αN | βN | βD | |
|---|---|---|---|---|---|---|---|---|
| Fano increasing with contrast (n = 34) | 2.40 | 1.55 | 5.8 | 54.8 | 11.3 | 12.6 | 1.70 | 1.60 |
| Fano decreasing with contrast (n = 138) | 1.87 | 3.56 | 10.9 | 38.7 | 8.7 | 10.1 | 1.53 | 1.30 |
| p value (different means) | 0.04 | 2 × 10−10 | 0.0003 | 0.02 | 0.13 | 0.11 | 0.003 | 9 × 10−6 |

↵ap values are for the difference between the means of the two subpopulations. For Fano factors, p values are computed on the logarithm. Because these analyses use the best-fit parameters of the RoG model, they were performed on the subsets of neurons with goodness of fit >0.5 (32 of 34 neurons for the first row; 120 of 138 neurons for the second row).
