Comparison of GRM3−/− and wild-type (WT) mice in two versions of the Neophagia Test.
| Task & measure | WT | GRM3−/− | Statistics |
|---|---|---|---|
| Neophagia I (Milk/Jug) | |||
| Latency to contact (s) | 3 (2–4.5) | 4 (2.5–8.5) | U = 85; p = 0.254 |
| Latency to drink (s) | 44 (12.5–85) | 12 (4.5–30) | U = 73.5; p = 0.106 |
| Latency to drink – latency to contact (s) | 42 (9.5–83) | 3 (2–25) | U = 72; p = 0.093 |
| Neophagia II (Noyes/Y-maze) | |||
| Latency to contact (s) | 40 (20–128.5) | 18 (10.5–28) | U = 65.5; p = 0.051 |
| Latency to eat (s) | 217 (147.5–279.5) | 110 (77.5–160.5) | U = 39; p = 0.002** |
| Latency to eat – latency to contact (s) | 108 (82.5–216.5) | 93 (36–140) | U = 89.5; p = 0.340 |
**p < 0.01. Non-parametric data are presented as median (inter-quartile range) and were analysed with Mann–Whitney U-tests. n = 15 WT; n = 15 GRM3−/−.
