title: Back-scattered electron imaging of sections through the cochlea: a new technique for studying cochlear morphology.
abstract: A new technique for studying the morphology of the cochlea is described. The development of back-scattered electron (BSE) detectors has allowed the examination of heavy-metal stained tissues by scanning electron microscopy. Comparison with light microscopy on adjacent resin sections through whole decalcified cochleae demonstrated that the back-scattered electron technique provides equal or superior clarity and resolution throughout the light microscope range of magnification, allows identification of lysosomes, mitochondria and endoplasmic reticulum, and extends useful magnification into the range previously associated only with transmission electron microscopy. Back-scattered electron imaging enables the study of sections of the undissected cochlea at high magnifications and resolution.
