Morphological evaluation of excitotoxic damages by electron microscopy. In vehicle tissue, type I hair cells (I) surrounded by calyx nerve endings and supporting cells (sc) were in order. In CM tissue, supporting cells (sc) were still in order, but type I hair cells (I) were separated by vacuoles. In injured inner ear, most hair cell type became undetermined (asterisk) and numerous swollen nerve terminals below hair cells were observed. Scale bars = 2 μm, n = 3/ group
