Transcranial magnetic stimulation (TMS) is a neurophysiologic technique to noninvasively induce a controlled current pulse in a prespecified cortical target. This can be used to transiently disrupt the function of the targeted cortical region and explore causal relations to behavior, assess cortical reactivity, and map out functionally relevant brain regions, for example during presurgical assessments. Particularly when applied repetitively, TMS can modify cortical excitability and the effects can propagate trans-synaptically to interconnected cortical, subcortical, and spinal cord regions. As such, TMS can be used to assess the functional integrity of neural circuits and to modulate brain activity with potential therapeutic intent.
经颅磁刺激(TMS)是一种神经生理学技术,用于在预先指定的皮质靶点无创地诱导可控电流脉冲。这可用于短暂破坏目标皮质区域的功能,并探索与行为的因果关系、评估皮质反应性以及绘制功能相关的脑区,例如在术前评估期间。特别是当重复应用时,TMS可以改变皮质兴奋性,其效应可通过突触传递到相互连接的皮质、皮质下和脊髓区域。因此,TMS可用于评估神经回路的功能完整性,并以潜在的治疗目的调节脑活动。
