Electric STC widthsa
| Electrode configuration | Mean at 6 dB in μm (SD) | Number of animals | Number of valid STCsa |
|---|---|---|---|
| VP balls radial | 429.0 (175.5) | 9 | 49/122 |
| VP balls off-radial | 750.9 (335.2) | 3 | 17/24 |
| VP balls longitudinal | 718.5 (207.2) | 5 | 6/18 |
| VP balls monopolar | >1500 | 1 | 0/25 |
| Banded tripolar | 547.7 (58.4) | 3 | 4/16 |
| Banded bipolar | 684.1 (270.9) | 3 | 13/32 |
| Banded monopolar | >1500 | 7 | 6/84 |
aWidth in μm of the 25% rate contour at 6 dB above threshold. A width of 400 μm (4 intervals of 100 μm) would indicate evoked activity at 5 adjacent sites along a 16-site recording probe.
