Table 1.
Numbers and percentages of significantly offset-responsive or onset-responsive neurons in auditory thalamus of ectopic and nonectopic micea
| Offset-responsive/onset-responsive | Nonectopic mice | Ectopic mice | Fisher's test pb | |
|---|---|---|---|---|
| All MGB | Offset-responsive | 183/522 (35%) | 113/427 (26%) | 0.0048 |
| Onset-responsive | 504/522 (97%) | 414/427 (97%) | 0.85 | |
| Onset-responsive among offset-responsive | 178/183 (97%) | 111/113 (98%) | 0.71 | |
| Ventral MGB | Offset-responsive | 112/314 (36%) | 62/248 (25%) | 0.0077 |
| Onset-responsive | 304/314 (97%) | 237/248 (96%) | 0.50 | |
| Onset-responsive among offset-responsive | 107/112 (96%) | 61/62 (98%) | 0.42 | |
| Dorsal MGB | Offset-responsive | 45/101 (45%) | 23/69 (33%) | 0.15 |
| Onset-responsive | 96/101 (95%) | 68/69 (99%) | 0.40 | |
| Onset-responsive among offset-responsive | 45/45 (100%) | 22/23 (96%) | 0.34 | |
| Medial MGB | Offset-responsive | 20/81 (25%) | 22/101 (22%) | 0.72 |
| Onset-responsive | 79/81 (98%) | 101/102 (99%) | 0.58 | |
| Onset-responsive among offset-responsive | 20/20 (100%) | 22/22 (100%) | 1.00 |
aThe vast majority of offset-responsive neurons were also onset-responsive (96%–100% in all the table groups).
bProbability of the observed results under the null hypothesis that the proportion of responsive cells is no different in ectopic and nonectopic animals (Fisher's exact test).
