Table 2.
Talairach coordinates of sources during the N1 period of the target stimulus (140–200 ms).
| Source | Brodmann area | Talairach coordinates (mm) | p-value (latency in ms) | |||
|---|---|---|---|---|---|---|
| X | Y | Z | Alerting (DC vs NC) | Orienting (SC vs CC) | ||
| L Anterior temporal lobe | −31.5 | −2.9 | −11.3 | NS | NS | |
| L Occipital lobe | BA19 | −24.5 | −65.9 | 2.7 | = 0.002 (155–188) | < 0.0001 (140–188) |
| R Occipital lobe | BA19 | 24.5 | −58.9 | 2.7 | = 0.003 (140–177) | = 0.006 (162–193) |
| R Anterior temporal lobe | BA38 | 31.5 | 4.1 | −18.3 | = 0.009 (174–200) | NS |
The table presents the p-values for alerting (double-cued vs non-cued stimuli) and orienting (spatially-cued vs centre-cued stimuli) sources and the latency of their effects. NS denotes not significant.
