The division of the brain that surrounds the cerebral aqueduct is the periaqueductal gray (PAG).

Step-by-step explanation:

The PAG is a region of gray matter located around the cerebral aqueduct within the midbrain. It plays a role in various functions, such as pain modulation, defensive behaviors, and autonomic regulation.

The division of the brain that surrounds the cerebral aqueduct is the midbrain. The cerebral aqueduct is a narrow tube-like structure that connects the third ventricle in the diencephalon to the fourth ventricle in the brainstem. The midbrain is located between the diencephalon and the pons, and it is responsible for various functions such as vision, hearing, motor control, and regulation of sleep and wake cycles.
