Quizplus · Accepted Answer

Myelination of axons in the brain typically occurs during infancy and early childhood, so if Ruthie's visual cortex has not yet fully myelinated, she is likely less than one year old. Option B (toddler) and C (preschooler) both suggest that Ruthie is older than one year and therefore it is unlikely that her axons in the visual cortex are not fully myelinated. Option D (50 years old) is incorrect as myelination of axons in the brain is a developmental process that typically occurs in childhood, not in adulthood.
