We have previously proposed that there are at least two initial molecular transduction mechanisms needed to explain specific and nonspecific biological effects of weak magnetic fields. For the specific effect associated with animal magnetic navigation, the radical pair mechanism is the leading hypothesis; it associates the specialised magnetic sense with the radical pairs located in the eye retina. In contrast to the magnetic sense, nonspecific effects occur through the interaction of magnetic fields with magnetic moments dispersed over the organism. However, it is unlikely that the radical pair mechanism can explain such nonspecific phenomena. In order to explain these, we further develop our physical model for the case of magnetic moments residing in rotating molecules. It is shown that, in some conditions, the precession of the magnetic moments that reside on rotating molecules can be slowed relative to the immediate biophysical structures. In terms of quantum mechanics this corresponds to the mixing of the quantum levels of magnetic moments. Hence this mechanism is called the Level Mixing Mechanism, or the LMM. The results obtained are magnetic field-dependences that are in good agreement with known experiments where biological effects arise in response to the reversal of the magnetic field vector.
我们之前曾提出，至少需要两种初始分子转导机制来解释弱磁场的特异性和非特异性生物学效应。对于与动物磁场导航相关的特异性效应，自由基对机制是主要假说；它将专门的磁性感觉与位于眼睛视网膜中的自由基对联系起来。与磁性感觉相反，非特异性效应通过磁场与分散在生物体中的磁矩相互作用而发生。然而，自由基对机制不太可能解释这种非特异性现象。为了解释这些现象，我们进一步发展了我们的物理模型，用于研究位于旋转分子中的磁矩的情况。结果表明，在某些条件下，位于旋转分子上的磁矩的进动可以相对于即时的生物物理结构减慢。从量子力学的角度来看，这对应于磁矩的量子能级的混合。因此，这种机制被称为能级混合机制，或 LMM。所得到的结果是磁场依赖性的，与已知的实验结果非常吻合，这些实验结果表明，生物效应是由于磁场矢量的反转而产生的。
