    Brief exposure of juvenile rats to noise impairs the development of the response properties of inferior colliculus neurons

  • Original language description

    Temporary impairment of the auditory periphery during the sensitive period of postnatal development of rats may result in a deterioration of neuronal responsiveness in the central auditory nuclei of adult animals. In this study, juvenile rats (postnatalday 14) were exposed for 8 min to intense broad-band noise; at the age of 3-6 months, the excitatory and inhibitory response areas of neurons in the central nucleus of the inferior colliculus were recorded under ketamine-xylazine anaesthesia in these animals and compared with those of age-matched controls. The response thresholds were similar in the exposed and control animals. The frequency selectivity of low-frequency neurons was comparable in both groups; however, high-frequency neurons had significantly wider excitatory response areas in the exposed rats, indicating disrupted development of high-frequency hearing. Forty-one per cent and 25% of neurons in exposed animals and in controls, respectively, lacked a distinct inhibitory are
