FIG. 5.

Development of GI motor patterns is incomplete in Sparse mutants. STMaps at 5 dpf (A), 7 dpf (B), and 9 dpf (C) show relatively few contractions when compared to control larvae (see Fig. 1). Motor patterns are poorly coordinated with propagating contractions moving in the oral and the aboral directions (see A). Coordinated motility patterns were observed in 1 of 4 larvae at 5 dpf, 5 of 12 larvae at 7 dpf, and 4 out of 14 larvae at 9 dpf (D). The total number of contractions did not change during development (E); p>0.05.
