Peak latencies and amplitudes obtained from group mean RCSE waveforms after dipole optimization constrained by prior for V1, V2, and V3, and three levels of luminance contrast
| Visual area | Contrast (%) | Peak latency | Peak amplitude | ||
|---|---|---|---|---|---|
| Mean (msec) | 95% confidence | Mean (nAm) | 95% confidence | ||
| 15 | 99.9 | 94.8–105.6 | 7.1 | 5.5–9.4 | |
| V1 | 71 | 80.7 | 76.8–84.6 | 13.8 | 11.3–17.1 |
| 95 | 77.6 | 73.9–79.4 | 15.9 | 13.4–19.9 | |
| 15 | 110.8 | 106.4–113.7 | 5.7 | 3.6–7.6 | |
| V2 | 71 | 98.1 | 95.8–99.2 | 9.6 | 6.7–12.4 |
| 95 | 91.8 | 90.6–94.4 | 11.3 | 7.9–14.6 | |
| 15 | 109.4 | 106.8–118.9 | 4.4 | 2.7–6.0 | |
| V3 | 71 | 102.1 | 96.5–104.6 | 7.7 | 5.2–10.3 |
| 95 | 95.6 | 92.0–99.2 | 9.0 | 6.2–12.0 | |
95% confidence intervals were derived from bootstrap resampling. Peak amplitudes correspond to negative (inward) currents, but for simplicity are shown without negative signs.
