Baseline acoustic startle response for D2R, D3R, and D4R mutant mice
| Wild-type (+/+) | Heterozygote (+/−) | Knock-out (−/−) | |
|---|---|---|---|
| D2R Male | 236.6 ± 34.8 | 347.4 ± 30.2 | 289.4 ± 41.4 |
| D2R Female | 202.2 ± 35.6 | 223.0 ± 22.6 | 204.4 ± 22.2 |
| D3R Male | 174.7 ± 56.4 | — | 212.7 ± 80.0 |
| D4R Male | 308.6 ± 29.2 | — | 235.0 ± 31.6 |
| D4R Female | 231.2 ± 26.6 | — | 204.2 ± 23.6 |
There were no significant differences in the startle response between genotypes for each mutant strain tested (p > 0.05). Values (arbitrary units) represent mean ± SEM startle magnitude.
