Unfortunately, the original publication of this paper contained error in the presentation of Fig. 3. In Fig. 3d, the type of stimulation should be manual stimulation. The correct Fig. 3 is given below.

Fold change in GIR at steady state, during stimulation and after stimulation in controls and PCOS rats with a and b no stimulation, c and d manual stimulation, e and f electrical stimulation. g Differences in the area under the curve (ΔAUC/min) in controls and PCOS rats. Values are expressed as the mean ± SEM. The differences in fold changes in GIR were determined with repeated measurement ANOVA with Bonferroni post hoc test. Changes in the AUC/min were analyzed by two-way ANOVA with the Tukey post hoc test. **P < 0.01; ***P < 0.001 versus no stimulation; +++P < 0.001 versus manual stimulation
