The Effect of Acoustic Stimulation During the Sensitive Period of Development on the Response Properties of Inferior Colliculus Neurons in the Rat

Popis výsledku v původním jazyce

It was shown previously that the exposure of adult rats to an acoustically enriched environment (EE) improves the response parameters of cortical neurons. The auditory system of rats, however, undergoes extensive refinement during early ontogeny; furthermore, cortical and sub-cortical structures may be influenced differently by an EE. For this reason, we explored the effect of an EE during early postnatal development on the response properties of inferior colliculus (IC) neurons. In the period from14 to28 postnatal days, the rats were exposed 12h a day to complex acoustic stimulation consisting of a broad-band rippled noise (average level 55dB SPL) with six embedded signals (at 60dB SPL), three of which triggered a reward release. At the age of 3 months, the response properties of the IC neurons of the enriched rats were recorded and compared with those obtained from age-matched controls raised under standard conditions. As the frequencies of the embedded signals ranged from 3 to 8 kH
