TABLE 1.
Comparison of the number, BF range, median spontaneous rate (SR), and percentage of zero-SR neurons in unexposed and exposed rats
| Type | Unexposed | Exposed | ||||||
|---|---|---|---|---|---|---|---|---|
| N | BF range (min, max) | Median SR (spikes/s) | Zero-SR (%) | N | BF range (min, max) | Median SR (spikes/s) | Zero-SR (%) | |
| All | 149 | −4.2, 1.5 | 10.4 | 24.2 | 232 | −3.7, 1.7 | 14.1 | 25.0 |
| V | 42 | −4.2, 1.3 | 1.7 | 57.1 | 62 | −3.5, 1.7 | 7.7 | 46.8 |
| I | 59 | −3.8, 1.3 | 8.0 | 15.3 | 57 | −3.7, 1.7 | 10.5 | 26.3 |
| O | 40 | −2.4, 1.3 | 18.4 | 7.5 | 53 | −3.4, 1.7 | 19.5 | 5.7 |
| X | 8 | −1.9, 1.5 | 19.0 | 12.5 | 27 | −3.7, 1.7 | 15.0 | 3.7 |
| Tail | 0 | 33 | −3.5, 1.1 | 11.1 | 30.3 | |||
Number of units (N) indicates the total number of units in each sample. BF range is expressed in octaves re EDGE. Median SR is based only on spontaneously active units with BFs within two octaves of the EDGE
