Question

Quizplus · Accepted Answer

The left planum temporale is larger in infants, which suggests that an inborn neural mechanism for language exists. This region of the brain is known to be involved in language processing, and its larger size on the left side is associated with better language skills. This finding supports the idea that language may be at least partially innate.
