Experimental design of behavioral analysis and swimming trajectory. a Schematic diagram of the experimental apparatus: 1, monitor; 2, computer system; 3, camera; 4, glass aquarium; 5, biological sample (Xenopus larvae); 6, illuminator. b Quantification of swimming behavior. The maximum and the minimum values of the swimming trajectory (red line) in both the X- and Y-axis (XMAX, XMIM, YMAX, YMIM) were obtained from the recorded trajectory. Swimming area (light gray) is derived from max-min value of swimming trajectory
