note

• typically, only the right auditory cortices play a important role in the processing of melodies. the task in this study induces bilateral activation of auditory cortex after cTBS. this combined with the tendency of  hemispheric asymmetries to be relative (rather than absolute) may explain why the authors found no improvement in task performance when stimulating the Left HG, as it contributes less to the processing.

Interestingly, we observed a correlation between the fMRI response in the left HG after TMS targeting the right HG and behavioral facilitation: a higher fMRI response in the left HG was associated with a higher facilitatory behavioral effect. (pdf)
