Across-subjects onset latency means ± SDs (Medians) in source space.
| Source latencies (ms) Across-subjects values using bootstrapping |
Heschl’s gyrus Mean ± SD (Median) |
Calcarine cortex Mean ± SD (Median) |
|---|---|---|
| Auditory stimuli | 25 ± 2 (25) | 55 ± 18 (62) |
| Visual stimuli | 58 ± 17 (65) | 48 ± 6 (48) |
| AV stimuli | 25 ± 2 (25) | 46 ± 4 (45) |
| AV Interaction (20 Hz LPF) | 131 ± 27 (125) | 126 ± 56 (133) |
In this analysis the evoked responses from each hemisphere and subject were bootstrapped. In addition, AV interaction responses were low-pass filtered at 20 Hz to mitigate SNR problems caused by the operation. For the corresponding values for A/V/AV stimuli extracted from the individual subject values without bootstrapping, see Table 4.
