Effect of virtual lesions of the left AIP on the grip force scaling. A, Virtual lesions of the left AIP (experiment 1) yielded an increase in the grip force peak when compared with control conditions, regardless of the hand used to grasp the manipulandum. Lesioning the right AIP had no effect. B, Effect of left AIP lesions on the preloading phase. A significant increase of the preloading phase duration was found after left, but not right, AIP lesions. Error bars represent one SD. *p < 0.05. C, Time course of the AIP contribution to grip force scaling. Experiment 4 showed that the GF peak increased significantly only when TMS was delivered 100 and 150 ms (open circles) after the GO signal when compared with control condition (sham; filled circles). D, Time course of the effects of AIP lesions on the preloading phase as determined in experiment 4. The effect on the preloading phase has the same time course as that found for the grip force peak. Same conventions as in C. Error bars represent one SD. *p < 0.05.
