Anterior-posterior cross section. This figure shows a confocal image of anterior-posterior cross section number 6 of the right utricle. All of the anterior-posterior cross sections (12 total) were sliced at 100 μm increments. They are numbered sequentially from 1, indicating the lateral end of the utricle to 12, indicating the medial end. Also displayed in this figure is the curve fit used to locate the EL, identified with cyan squares, and the top of the OL, identified with yellow circles.
