The 3D rotating image shows a reconstructed guinea pig cochlea. The 3D reconstruction was created using Amira 4 software from Mercury Computer Systems, Inc. using guinea pig temporal bone slices prepared in paraffin. The slices were 20 µm thick and every tenth slice was used in the reconstruction.
The scala tympani is shown in green, scala media in purple, and scala vestibuli in gray. The oval window, at the base of the scala vestibule, is shown in blue, and the round window, at the base of the scala tympani, is shown in light blue. The location of cochleostomy and cannula insertion is marked with the purple tube. The locations along the scala tympani for best hearing of various frequencies are denoted with the red frequency values.
Special thanks to Haobing Wang, Eaton-Peabody Lab, Massachusetts Eye & Ear Infirmary for her assistance in creating the guinea pig cochlea reconstruction.
