Motor patterns in W mutants. In both Wsh/Wsh (A) and W/Wv (C) mutants, in the absence of carbenoxolone, contractions clustered about lines of simultaneity (dotted green lines), i.e., stripes, but deviated more from this line than in the pinstripe pattern in wild-type mice. Carbenoxolone (cbx) induced a pinstripe pattern indistinguishable from wild-type mice in both Wsh/Wsh (B) and W/Wv (D). A and B: female Wsh/Wsh, perfused lumen, 2 μM/min carbenoxolone. C and D:, female W/Wv, perfused lumen, 100 μM carbenoxolone. See Fig. 8 for n numbers and statistics.
