摘要
行为学实验表明,许多鸟类能够感受到地磁信息,并利用地磁信息完成迁徙或归巢。地磁场信息能提供可靠导航信息,磁力线可提供罗盘信息,而磁场强度和倾角可提供位置信息。文章介绍了鸟类磁感受机制的两种重要假说——基于磁铁矿的磁感受假说和化学磁感受假说,阐明了两种假说的理论原理及实验证据,对地磁信息传导神经通路与处理脑区做了评述,并展望了其发展方向。
Behavior experiments have shown that many birds can sense the Earth＇s magnetic field and use it as a cue for homing and migration. The geomagnetic field can provide birds with a reliable and omnipresent cue for navigation, with the vector of the geomagnetic field providing directional reference （compass） while changes in intensity and/or inclination providing positional information （map）. In this paper, the two prevalent modes of avian magnetoreception, magnetite-based magnetoreception and chemical magnetorecepfion, were documented and their experimental evidences were summarized. Finally following the review and comments on the mode of transduction for the magnetic sense and brain regions underlying magnetic information processing, the future research directions were discussed.
