Facial Motor Pools Exhibit a Loose Spatial Topography that Is Maintained in Caudal Migration Mutants

(A) Across wild-type larvae, the LO motor pool (teal) extends throughout the entire facial motor nucleus, whereas the IH+ (purple) and HHs (orange) motor pools are found in more restricted but still overlapping regions—in the middle and dorsomedial portions of the nucleus, respectively.

(B and C) In llk(rw16) mutant larvae (B) and pk1b(fh122) mutant larvae (C), the cross-sectional topography of the motor pools is maintained ( Table S1).

All fish were backfilled at 4 dpf and imaged at 5 dpf. n, number of fish used in each condition. Histograms illustrate the distribution of cells along the mediolateral and dorsoventral axes, binned at 20-μm intervals. See also Figure S1.
