Retinal input is required to initiate local but not outward movement. a Lock index for R-turns during baseline and immediately following loss of light (T0) during 10 s recordings, for sham operated (ctrl) and enucleated (enuc) larvae. N = 41 larvae (ctrl, baseline), 53 (ctrl, T0), 44 (enuc, baseline), 59 (enuc, T0). * P < 0.001. b, c Fractal dimension (b) and meander (c) of path trajectories during dark response for control (black circles, N = 29) and enucleated larvae (grey circles, N = 34). * P < 0.05 for control compared to enucleated larvae. Dashed lines show mean values for enucleated larvae under full-field illumination. Inset: Representative traces of first 2 min of dark for control (left) and enucleated (right) larvae. Scale bar 20 mm. d Mean meander for enucleated larvae during full-field illumination (base) compared to the first 2 min after loss of illumination (0–2) and from 3–10 min after loss of illumination (3–10). * P < 0.001, paired t-test compared to baseline
