EARLY SENSORY PRESBYCUSIS

Description : There is a loss of hearing in the highest frequencies, and a concomitant loss of the hair cells in the basal turn (left ear) of the cochlea. There is also evidence of secondary neural degeneration as shown by the loss of spiral ganglion cells in the basal turn of the cochlea. (Large circles indicate a hair cell was present; dots indicate a hair cell was missing.)
