Chinchilla model hearing loss

WebA chinchilla’s hearing range is broadly similar to ours. The average chinchilla’s hearing range runs from 50 Hz at the lower end of the spectrum to 33 kHz at the higher end. For comparison, the human hearing range is between 20 Hz and 20 kHz. This means that chinchillas are lots better at hearing higher pitched noises than we are, but ... WebWhereas normal-hearing chinchillas demonstrate contralaterally dominant neural activity in the inferior colliculus, animals that have undergone chemical deafening show symmetric inferior colliculus activation. Loss of contralateral bias in auditory midbrain sensitivity is predicted to result in a reduced capacity for binaural hearing.
