Postnatal exposure to tones alters the tuning characteristics of inferior collicular neurons in the rat.
Young rats were exposed to either a 4 or 20 kHz steady tone during the first 3 weeks after birth, and then single unit responses to pure tones were studied at their inferior colliculi (IC). The best frequencies (BF's) of the cells showed strong clustering around the frequency of exposure.
