Fig. 1. LDT experiment parameter introduction The figure displays how data were retrieved from one exemplary embryo. A) Total distance was calculated based on zebrafish embryo low activity (grey dashed line, <0.3 cm/s), cruising (green line, 0.3–1 cm/s) and bursting (red line, > 1 cm/s). Total time moved was calculated based on cruising and bursting only as including low activity would add up to the whole minute of tracking. Bursting (red line) was used as an additional parameter for which sum and mean were calculated. B) depicts an exemplary behaviour course of an embryo in darkness (grey background) and the timely occurrence of min. and max.. Dots represent exemplary 1-min time bins, which were extracted for min and max analyses. Created with BioRender.com.
