In Magnetic Resonance Imaging scanner environments, the continuous Lorentz Force is a potent vestibular stimulation. It is nowadays so well known that it is now identified as Magnetic vestibular stimulation (MVS). Alongside MVS, some authors argue that through induced electric fields, electromagnetic induction could also trigger the vestibular system. Indeed, for decades, vestibular-specific electric stimulations (EVS) have been known to precisely impact all vestibular pathways. Here, we go through the literature, looking at potential time varying magnetic field induced vestibular outcomes in MRI settings and comparing them with EVS-known outcomes. To date, although theoretically induction could trigger vestibular responses the behavioral evidence remains poor. Finally, more vestibular-specific work is needed.
在磁共振成像扫描仪环境中，持续的洛伦兹力是一种强大的前庭刺激。现在，它已经广为人知，现在被称为磁前庭刺激（MVS）。除了 MVS，一些作者认为，通过感应电场，电磁感应也可能引发前庭系统。事实上，几十年来，人们一直知道前庭特异性电刺激（EVS）可以精确地影响所有前庭通路。在这里，我们查阅了文献，研究了 MRI 环境中潜在的时变磁场诱导的前庭结果，并将其与已知的 EVS 结果进行了比较。到目前为止，尽管理论上感应可以引发前庭反应，但行为证据仍然不足。最后，还需要更多的前庭特异性研究。
