Table IV.
Time sequence of cortical activation derived from SSVEP and transient VEP recordings (transient data are from Di Russo et al., 2005)
| SSVEPs | Transient VEPs | ||
|---|---|---|---|
| Onset | Peak | ||
| Modeled sources for upper quadrant stimuli | |||
| MTS (MT/V5) | 20 | 20 | 20 |
| pIPS (V3A+) | 38 | 41 | 50 |
| CoS/Fus (V4v, V4/V8+) | 64 | 75 | 88 |
| Modeled sources for lower quadrant stimuli | |||
| MTS (MT/V5) | 22 | 20 | 20 |
| pIPS (V3A−) | 42 | 40 | 46 |
| CoS/Fus (V4/V8−) | 65 | 71 | 85 |
Table shows time delays (expressed in ms) between neural activity in V1 and subsequent activity in the other cortical areas. For the SSVEP, phase differences were transformed to time differences (see Subjects and Methods). Group‐averaged data.
