Cross-links between stereocilia on guinea pig cochlea hair cell have been examined using transmission electron microscopy. The links have been seen in material fixed using (1) glutaradehyde/osmium and (2) glutaradehyde/ osmium/Ruthenium red. Side-to-side and row-to-row links form a regular lattice between stereocilia and consist of a number of strands. In the end of which are assoicated with electron dense material and at the mid-point between stereociliathe links often have a denser band visible along tha filament network. Guinea pig were exposed to the noise at an intensity of 110-120dB SPL for 2-3 hour. During the periods of noise induced threshold shift were examined. The stereocilia of the haircell were clumped together compared with control ears.
