Abdominal curvature data used in Fig. 4C

Abdominal curvature measurements made as described in the Extended Methods were used to calculate a mean curvature for each animal of each genotype before and during thermogenetic stimulation. Means of normalized curvatures were calculated across animals of each genotype and the significance of the difference of these means from 1 (i.e. the normalized curvature without stimulation) was estimated by t-test.
