Effects of a ramped LD cycle on light sampling behaviour. A Daily light environment sampling profile under a square 12:12 h LD cycle (green) and a ramped 12:2:8:2 h LD cycle (blue). B Number of light environment sampling events occurring during dawn (ZT22-0), the day (ZT0-12) and dusk (ZT12-14), under a ramped 12:2:8:2 h LD cycle. C Schematic demonstrating “no-go” or “go” decision making following light environment sampling behaviour. D Daily decision making profile showing “no-go” (red) and “go” (green) decisions under ramped 12:2:8:2 h LD cycle. White, grey and black bar shows timing of light, light ramp and dark, respectively (A, D). All results reported as mean across mice and days, ± SEM. **** p < 0.001, ** p < 0.01, * p < 0.05, between condition comparisons
