摘要：

经颅磁刺激(TMS)可以暂时性地改变特定大脑区域的神经活动以研究该脑区在时间认知中的作用。高频TMS通常增加皮质兴奋性,用高频TMS刺激右侧背外侧前额皮质可以影响秒范围的时距知觉,刺激小脑可以影响毫秒范围的时距知觉。经颅磁刺激可以作为探讨时间认知神经机制的有效工具,并可以作为脑损伤病人改善时间认知能力的有效治疗手段。

Transcranial magnetic stimulation(TMS), which can temporarily change the neural activity of a definite brain area, has been used to explore the role of the brain regions in time perception. Generally, high-frequency TMS produces increasing excitability of the cortical network. High-frequency repetitive TMS, when applied to the right dorsolateral prefrontal cortex (DLPFC), can affect the perception of second range intervals; while repetitive TMS of cerebellum can affect the perception of millisecond time processing. Repetitive TMS should be an effective tool in neural mechanism of time perception and plays an important role in neurorehabilitation.
