Activity in the ILH at the sight of prey
a, The trajectories of single paramecia over 942 s are shown with the colour-coded changes in the intensity of GCaMP6s fluorescence in the left and right ILH areas in 5 dpf UAShspGCaMP6s;hspGFFDMC76A larvae. The data from 4 larvae were merged into a single larval image. Scale bar: 1 mm. The length of the arrowhead indicates the distance travelled by the paramecium in 60 ms. b, Average increase in the Ca signals in each 5° bin. The data are the same as those shown in a. c, Average increase in the Ca signals in the left and right hemifields. The data are the same as those shown in a. Mean ± S.D.
