TAMPA—  The University of South Florida researchers at the Global Center for Hearing and Speech Research lab are studying brainstem cells that determine age-related hearing loss. Mackenzie Ott, a Neurophysiologist, (right) and Dr. Xiaoxia Zhu, M.D., a Biological Scientist, (left) are staining sections to mount on slides in order to examine under a microscope. The slides will allow the researchers to visualize anatomical differences in brainstem cells and how they relate to age-related structural and functional changes in auditory network cells involved in Presbycusis, or age related hearing loss. Ott and Zhu are using a hematoxylin and eosin stain kit, also known as H&E stain, to conduct their research. It is the most widely used stain in medical diagnosis. Without the stain it would be difficult to see biological tissue under a microscope. The stain gives the tissue contrast and highlights particular features of interest.
