Question

Quizplus · Accepted Answer

The brain is divided into two hemispheres, and each hemisphere is further divided into four lobes (frontal, parietal, temporal, and occipital lobes). This division of the brain is a well-established anatomical structure. Option B is incorrect because language typically depends on activity in the left hemisphere, not the right. Option C is incorrect because humor and the use of metaphors involve complex cognitive processing that is not limited to one particular hemisphere. Option D is incorrect because the forebrain is the most anterior portion of the brain, and is located above (rather than nearest to) the spinal cord.
