In the human brain, the cerebrum wraps around the

The cerebrum, which is the largest part of the brain and responsible for higher cognitive functions, wraps around the thalamus. The thalamus acts as a relay station for sensory information, processing and directing signals to the appropriate areas of the cerebral cortex. This arrangement facilitates the integration of sensory input and the coordination of various cognitive processes.
The cerebrum does not wrap around the cerebellum, pons, or medulla. The cerebellum is located at the back of the brain. The pons is in the brainstem, below the cerebrum and in front of the cerebellum. The medulla, also part of the brainstem, is situated below the pons.
