生物磁铁矿与磁接收器

Biomagnetite and magnetoreceptor in the living body

很多生物的行为受到地磁场的影响,并利用地磁场作为长距离迁移和飞行的信息.研究者认为,这些生物体内存在磁接收器,是磁接收器接收到地磁信息并传递给神经组织.由于生物磁铁矿在生物体中的广泛存在,以生物磁铁矿为基础的磁接收器机制被提出.本文中主要综述了生物磁铁矿的物理特性、与神经组织的关系、以生物磁铁矿为基础的磁接收器模型以及某些实验验证结果.

Behaviors of many living bodies are influenced by the geomagnetic field which is used as the in- formation of long distance moving and flying. The investigators think that magnetoreceptor exists in these living bodies, and it is the magnetoreceptor that incepts the geomagnetic field information and transfers it to nerve system. Because of the biomagnetite existed abroad in living bodies, the magnetore- ceptor models based on the biomagnetite are brought forward. In this paper, the physical characteristic of biomagnetite, the relationship between biomagnetite and nerves, the magnetoreceptor models based on biomagnetite and many experimental results are summarized.
