7. The Cerebrum is the most highly developed part of the human brain. The Cerebrum is the most highly developed part of the human brain. It is here that things like imagination, thought, judgment, and decision occur. It is here that things like imagination, thought, judgment, and decision occur. The Brainstem is the region of the brain that connects the cerebrum with the spinal cord. The Brainstem is the region of the brain that connects the cerebrum with the spinal cord. Motor and sensory neurons travel through the brainstem allowing for the relay of signals between the brain and the spinal cord.
