Quizplus · Accepted Answer

The cortex of lower animals is typically small and smooth, while the human brain has a highly complex, folded cortex. Option B is incorrect because it is describing the human cortex. Option C is incorrect because "corticalized" is not a term commonly used to describe the characteristics of animal brains. Option D is also incorrect because the human brain contains only about 20% of the neurons in the CNS.
