Figure 7. Extraocular nerve discharge during vertical axis rotation in larval Xenopus. A–F, Vertical axis rotation designed to minimize utricle activation and maximally activate one vertical canal pair (C, inset) modulates the spike discharge of the superior (Sup) oblique nerve in stage 47 animals (A–C) but does not modulate nerve activity in stage 46 animals (D–F). B and E show one cycle of the recordings in A and D at an extended time scale, respectively; the average ± SD (red area) of five animals over 30 cycles is summarized in C and F, respectively. G, H, A brief pressure pulse of endolymph Ringer's solution into the ipsilateral (Ipsi) posterior (Post) (G) and contralateral (Contra) anterior (Ant) vertical semicircular canal (H) in the same stage 46 specimen shown in D–F modulated the discharge of the superior oblique nerve. The scale bar in H also applies to G. Image published in: Lambert FM et al. (2008) Copyright © 2008. This image is reproduced with permission of the publisher and the copyright holder.
