Figure 3.

The relationship between rhombomere-derived territories and the domains of the vestibulo-ocular and vestibulospinal groups in horizontal sections at E16.5, assessed by retrograde labeling with BDA in the r3/r5::lacZ mouse. bc, Brachium conjunctivum; Cb, cerebellum; v, fourth ventricle. Arrows in D and E indicate the subpopulation of cC-VO neurons located in the abducens nucleus. Boxes in C and E indicate migratory cell streams between r3 and r5. Arrowheads in G and H indicate reticulospinal neurons that are also labeled by the spinal BDA application site used to label vestibulospinal neurons. Scale bars: A–D, G, H, 200 μm; E, F, 400 μm.
