Dysfunction of the basal ganglia-thalamocortical motor circuit is a fundamental model to account for motor symptoms in Parkinson's disease (PD). Using high-frequency repetitive transcranial magnetic stimulation (rTMS) over the supplementary motor area (SMA), we investigated whether modulation of SMA excitability engenders therapeutic effects on motor symptoms in PD. In this double-blind placebo...

Tinnitus is described as the perceived sensation of sound in the absence of acoustic stimulation. According to recent studies, it is one of the most common health problems disturbing patients in their daily lives. Although previous studies have focused more on the peripheral features, such as inner ear pathologies, as the possible causes of tinnitus, accumulating evidence suggests that tinnitus...

Non-invasive brain stimulation (NBS) is a promising treatment for major depressive disorder (MDD), which is an affective processing disorder involving abnormal emotional processing. Many studies have shown that repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) over the prefrontal cortex can play a regulatory role in affective processing. Alth...

Repetitive transcranial magnetic stimulation (rTMS) is an established technique for non-invasive stimulation of human cortex. Although studies have shown an influence of rTMS on single cortical regions and on simple behavioral response patterns, its influences on the dynamics of task-related activity in cortical networks have not been characterized. We provide such a characterization by showing...

The aim of the present study was to determine the effects of high frequency repetitive transcranial magnetic stimulation (rTMS) over different neuroanatomical areas [left and right doroslateral prefrontal cortex (DLPFC) and right cerebellar hemisphere] on time production task. The study was performed in 16 healthy right-handed men with a cross-over, within subject repeated measures design. Ther...

Obsessive-compulsive disorder (OCD) is a chronic, disabling disorder. Ten percent of patients remain treatment refractory despite several treatments. For these severe, treatment-refractory patients, repetitive transcranial magnetic stimulation (rTMS) has been suggested as a treatment option. Since 1997, in published trials, a total of 110 OCD patients have been treated with rTMS. This review ai...

Transcranial magnetic stimulation (TMS) is a safe, noninvasive, and painless way to stimulate the human motor cortex in behaving human subjects. When it is applied as a single-pulse, measurements such as central conduction time, motor threshold, silent-period duration, recruitment curve, and mapping of muscle representation can be determined. Paired-pulse TMS is a useful way to examine cortical...
