Figure 1. Schematic depicting locations of nerve recording and electrical and pressure stimulation sites in the labyrinth in larval Xenopus. A, B, The activity of motor nerves innervating extraocular muscles were recorded with suction electrodes (A) after either electrical stimulation (Stim) of an identified semicircular canal nerve or displacement of the canal cupula (Cup) by pressure injection of endolymph Ringer's solution, e.g., into the horizontal (Hor) canal (B). C, Graph of body length (mean ± SD) versus developmental stage according to Nieuwkoop and Faber (1994). Superimposed on the graph is a photomontage of larval Xenopus from stages 42–49 showing the significant change in length and head size with age. The peak growth in larval size occurs between stages 46 and 49. Adjacent to each marker on the graph are the ages of the larvae in days postfertilization. Inf, Inferior; Lat, lateral; Med, medial; Opt, optic; Sup, superior; Utr, utricle. Image published in: Lambert FM et al. (2008) Copyright © 2008.
