Figure 1.

(A) Schematic representation of a dorsal view of the whole guinea pig utricular macula, with the arrows showing the polarization of receptor hair cells. The dashed line is the line of polarity reversal which used to be called the striola, but more recently it is recognized that the striola is a band of receptors as shown in the adjacent whole mount. (B) To show a corresponding whole mount of a guinea pig utricular macula treated by calretinin—the band of cells comprising the striola is clearly visible (54). Reprinted from Ref.
