Persistent influence of the early acoustic environment on inferior colliculus neurons

Popis výsledku v původním jazyce

During the early postnatal development of rats, the functional maturation of the auditory system strongly relies on the natural character of the incoming neural activity. In the current work we explore the effect of exposure to an acoustically enriched environment during early postnatal development on the response properties of inferior colliculus (IC) neurons in the adult rats. Starting on postnatal day 14, juvenile rats were exposed for two weeks, 12 hours a day, to a complex acoustic stimulation consisted of a temporally and spectrally modulated broad-band rippled noise (intensity 55 dB SPL) with several types of embedded target signals (intensity 60dB SPL), one of which triggered a release of glucose water. At the age of 3 months, the response properties of IC neurons related to frequency and sound intensity were recorded extracellularly under ketamine-xylazine anaesthesia, both in the enriched rats and in age-matched controls raised under standard housing conditions. In the enrich
