The analysis revealed that by 26 weeks of gestation, the primary auditory cortex was in a much more advanced stage of development than the nonprimary auditory cortex. (sciencedaily.com)

Between 26 weeks and about 40 weeks — the latter the equivalent of full - term birth — the nonprimary auditory cortex in the preterm infants matured quickly, partially catching up to the primary auditory cortex. (sciencedaily.com)
