Fig. 6. Schematic representation and comparison of hair cell polarity maps of the lamprey macula communis, and of the anterior and posterior maculae of the developing zebrafish inner ear. The schematic representation of the hair cell polarity map of the lamprey macula communis is a summary of Fig. 5E,F. Maps of the anterior and posterior maculae of the developing zebrafish inner ear were produced using data from Haddon et al. (Haddon et al., 1999). Hair cells with similar orientations in the two species are shown in the same colour.
