在红鲑鱼的前额中发现了生物磁感觉器官的新候选者。这个候选者是一个被许多磁性粒子包围的椭圆形细胞。描述了提取细胞的程序，并显示了 TEM（透射电子显微镜）图片。细胞的短轴和长轴分别约为0.65-0.75μm和1.3-1.8μm，磁性颗粒的直径范围为50-100nm。细胞还包括许多圆形细胞器。使用简化模型讨论了该器官如何感知磁场的可能机制，即磁性粒子的运动与施加的场之间的关系。 >
A new candidate for a biomagnetic sense organ has been discovered in the foreheads of sockeye salmon. This candidate is an elliptical cell encircled by many magnetic particles. The procedures for extracting the cells are described, and TEM (transmission electron microscopy) pictures are shown. The minor and major axes of the cells are about 0.65-0.75 mu m and 1.3-1.8 mu m, respectively, and the diameters of the magnetic particle range from 50 to 100 nm. The cell also includes a number of round organelles. A possible mechanism for how this organ senses magnetic field, that is, a relationship between the motion of magnetic particles and the applied field, is discussed using a simplified model. >
