Hair cell polarization patterns were investigated on the sensory macule of the sacculus and lagena of the lake whitefish. The saccular hair cells are divided into four groups, with all of the cells within a group having the same orientation. Saccular orientations are anterior, posterior, dorsal, and ventral with respect to the axis of the animal. Two groups, one dorsal and one ventral, are found on the lagena. The saccular orientations are significantly different from those in tetrapods. Since this organ appears to have different functions in fish and tetrapods it is likely that the orientation patterns in fish are adapted to some aspect of audition--perhaps directional localization of sound.
对湖白鲑的球囊和瓶状囊感觉斑上的毛细胞极化模式进行了研究。球囊毛细胞分为四组，同一组内的所有细胞具有相同的方向。球囊的方向相对于动物的轴线为前、后、背和腹。在瓶状囊上发现了两组，一组背侧，一组腹侧。球囊的方向与四足动物的显著不同。由于这个器官在鱼类和四足动物中似乎具有不同的功能，所以鱼类中的方向模式很可能是适应听觉的某些方面——也许是声音的定向定位。
