Figure 8

Effect of DCMD laser ablation on the escape behavior (see also Supp. Fig. S6). The timing of the Initial Joint Movement (IJM; box plots), a proxy for the start of flexor motoneuron activity in intact animals, in response to looming stimuli presented to the eye contralateral to the ablated DCMD was not significantly different from control (i.e., when looming stimuli were presented to the eye ipsilateral to the intact nerve cord). The timing of IJM, however, showed more variability (CVipsi=0.8, 0.5, 0.5 and CVcontra=2.68, 1.16, 0.8, for l/|v|=40, 80, and 120 ms, respectively). Inset illustrates the ablation configuration, with the left nerve cord sectioned (red scissors) and the DCMD laser ablated (blue arrows). Black and grey triangles indicate stimulated eyes; DIMD indicates the projection of the DIMD through the intact nerve cord.
