Summary

Attention deficit hyperactivity disorder (ADHD) patients have some problem with sustained attention. The dorsal anterior cingulate cortex (dACC) plays a key role for attention control. It has been found that the dACC has strong functional connectivity with ipsilateral motor area and parietal gyrus. Repetitive Transcranial Magnetic Stimulation (rTMS) is a sage and painless technique to activate cortical areas. The deep brain structure can be activated via stimulating superficial cortex by rTMS. For investigating the mechanism of sustained attention, this project is using functional magnetic resonance imaging (fMRI) to individualize the precise localization in motor area and parietal gyrus, and combining rTMS to activate the dACC.

Detailed description

Healthy subject is recruiting in this project. High rTMS will be performed. The 10-Hz stimulation is delivered at 100% of the subject's resting motor threshold via 60 trains of 3-s 10-Hz rTMS (30 pulses with 27-s duration per train).
