Figure 1.
MicroCT (12 μm voxel size, a1–d1) coregistered with a microMRI (48 μm voxel size, a2–d2) of a normal chinchilla labyrinth. Top image pair (a) is the most anterior slice; others are progressively further posterior. MicroCT reveals individual pores in the cribriform plate through which the superior vestibular nerve enters the labyrinth as it breaks into its three branches (b1). Note the close mutual proximity of these three superior vestibular nerve branches in this region. To achieve adequate signal to noise ratio and voxel density to clearly define endorgan neuroepitheilia, the MRI was acquired in a 12 Tesla magnet for 26 hours.
