本研究涉及的两个耳石受体器官，椭圆囊和囊状斑的二维和三维连接的真实形态。通过应用一种新的可视化方法，它利用了X射线显微断层扫描的应用程序和对比度增强的方法的基础上，整块染色在四氧化锇，我们能够克服问题的文物生产，如组织变形和损失的有价值的信息，是在以前的研究。一系列的1000多个轴向截面获得每个标本，随后形成了详细的2D和3D可视化的基础。我们对这些数据的解释表明，囊状黄斑与传统上认为的颞骨的弯曲骨表面紧密相连，但椭圆囊状黄斑仅在黄斑的前部区域与颞骨相连。皇冠版权所有（C）2007年出版的爱思唯尔B.V.保留所有权利。
The present investigation concerns the true morphology of the attachment of the two otolith receptor organs the utricular and the saccular maculae in two and three dimensions. By applying a new visualization method, which utilized the application of X-ray microtomography and a method of contrast enhancement based on en-bloc staining in osmium tetroxide, we were able to overcome problems of artefact production such as tissue distortion and loss of valuable information that was present in previous studies. A series of more than 1000 axial sections were obtained for each of the specimens, which subsequently formed the basis for detailed 2D and 3D visualizations. Our interpretations of these data reveal that the saccular maculae are closely attached to the curved bony surface of the temporal bone as traditionally believed, but the utricular macula is attached to the temporal bone only at the anterior region of the macula.
