The maturation of auditory cortical evoked responses between (preterm) birth and 14 years of age.
In this study we report on the maturation of the auditory cortical evoked response (ACR) waveform between (preterm) birth and 14 years of age. From the results it can be concluded that the ACR waveform morphology shows substantial age-dependent changes until the age of 14 years. Two transitional periods could be recognized. The first between 36 and 41 weeks conceptional age; the second between 4 and 6 years of age. The adult waveform complex is achieved between 14 and 16 years of age. Further research is needed to determine whether these transitional periods in the maturation of ACRs correspond with important functional changes of the central auditory system.
