Figure 1

Time series plots from behavior experiments. (a) Average activity index (top) and radial index (bottom) per second of 132 zebrafish larvae over the study period under light or dark period at either 9 am (left) or 2 pm (right) for 5, 6 or 7 dpf. Initial 20 minutes acclimation period (faded period), followed by 20 minutes of “spontaneous” swimming, then swimming under darkness (2 × 10 min, referred to as “dark intervals”, shaded period) and swimming in light after periods of darkness (2 × 10 min, referred to as “light intervals”). For the startle triggers of (b) dark flashes (DF) and (c) tapping (T), average activity for 9 am measurements are shown. The dashed grey lines indicate occurrence of the stimuli.
