Visual hemifield mapping using transcranial magnetic stimulation coregistered with cortical surfaces derived from magnetic resonance images.

The perception of a visual stimulus can be inhibited by occipital transcranial magnetic stimulation. This visual suppression effect has been attributed to disruption in the cortical gray matter of primary visual cortex or in the fiber tracts leading to V1 from the thalamus. However, others have suggested that the visual suppression effect is caused by disruption in secondary visual cortex. Here the authors used a figure-eight coil, which produces a focal magnetic field, and a Quadropulse stimulator to produce visual suppression contralateral to the stimulated hemisphere in five normal voluntee…

Dosage and safety of transcranial magnetic stimulation and transcranial direct current stimulation for managing patients with chronic musculoskeletal pain: a scoping review protocol.

INTRODUCTION: Although emerging evidence supports the short-term efficacy of transcranial magnetic stimulation (TMS), including repetitive TMS (rTMS) and theta-burst transcranial magnetic stimulation (TBS-TMS), and transcranial direct current stimulation (tDCS) for managing patients with chronic musculoskeletal pain (CMP), their clinical utility in managing CMP remains inconclusive.
