Sentences with phrase «nonprimary auditory cortex»

The team focused on the primary auditory cortex, which is the first cortical region to receive auditory signals from the ears via other parts of the brain, and the nonprimary auditory cortex, which plays a more sophisticated role in processing those stimuli.

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.

The team also found an association between the delayed development of the nonprimary auditory cortex in infancy and language delays in the children at age 2, suggesting that disruptions to this part of the brain as a result of premature birth may contribute to the speech and language problems often seen later in life in preemies, Monson said.

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.
