通过测量荧光素阈值(PTS)和刺激反应曲线，研究了低频(L-赫兹)重复经颅磁刺激对视皮质兴奋性的影响。超过视皮层的刺激导致视皮层兴奋性显著降低，表现为PT的增加。手部肌肉的运动阈值没有改变，表明这一效应的地形图特异性。这种干预在与过度兴奋的视觉皮质相关的情况下可能很有用。
The effects of low-frequency (l-Hz) repetitive transcranial magnetic stimulation on visual cortex excitability were investigated by measuring phosphene thresholds (PTs) and stimulus-response curves. Stimulation over the visual cortex led to significantly decreased visual cortex excitability, expressed as an increase in PT. The motor threshold of the hand muscles did not change, indicating the topographic specificity of this effect. This intervention may be useful in situations associated with a hyperexcitable visual cortex.
