Mean amounts of food eaten (in grams) and latency to start eating (in seconds) as well as total and reinforced wheel turns observed during the 3 d training period previous to the pharmacological experiments conducted on the ChR2 mice for the feeding and optical self-stimulation studies
| Training | Amount eaten (g) | Latency to eat (s) | Total wheel turns | Reinforced wheel turns | ||
|---|---|---|---|---|---|---|
| No light | Light | Active | Inactive | |||
| Day 1 | 0.24 ± 0.06 | 57.94 ± 1.54 | 32.89 ± 7.79 | 693.48 ± 125.95 | 32.57 ± 5.45 | 112.81 ± 9.70 |
| Day 2 | 0.31 ± 0.06 | 60 ± 0 | 25.11 ± 5.75 | 1148.88 ± 106.30 | 54.19 ± 22.99 | 143.38 ± 11.13 |
| Day 3 | 0.32 ± 0.06 | 60 ± 0 | 26.77 ± 6.95 | 1086.86 ± 142.13 | 40.52 ± 9.87 | 143.52 ± 15.11 |
The statistical analyses for each variable are as follows: amount eaten, main effect of days, F(2,12) = 2.61, p = 0.11, n.s.; latency to eat, χ2 = 30.56, p < 0.001, no significant difference between the latencies to eat observed during the no light trials during the 3 training days, as well as no differences between the latencies to eat observed during the light trials during the 3 training days; total wheel turns, main effect of days, F(2,12) = 4.88, p < 0.05; main effect of wheel, F(1,6) = 174.15, p < 0.001; days by wheel interaction, F(2,12) = 3.74, p = 0.06, n.s.; reinforced wheel turns, main effect of days, F(2,12) = 3.22, p = 0.08, n.s.
