Figure Lengend Snippet: Targets of rTMS. For 23 subjects in Experiment 1 and all the subjects in Experiment 2, targets of rTMS were chosen based on individual brain anatomy, as illustrated on one subject’s MRI scan by the orange markers. The orientation of the marker indicates the orientation of the TMS-related magnetic field at that region. In Experiment 1, the dlPFC and SPL were experimental targets and the PCG was used as a control. In Experiment 2, the FEF and IPS were experimental targets and PCG, once again used as a control area. The pseudocolor painting on the surface of the brain illustrates an estimated projection of the induced electric current produced by a TMS coil held over the dlPFC. The area in red indicates the area of maximal induced electric current.

Article Snippet: To date, neuroimaging techniques such as functional magnetic resonance imaging (fMRI) have failed to resolve conclusively this controversy, in part because they only provide correlational evidence about brain-behavior relationships ( Logothetis and Pfeuffer, 2004 , Fellows et al., 2005 ).
