Question

Quizplus · Accepted Answer

Primitive reflexes, such as the sucking reflex and rooting reflex, are controlled by lower parts of the brain and are present at birth. They are automatic responses to stimuli and do not require conscious thought or input from the cerebral cortex. Therefore, if the entire cerebral cortex were injured, these primitive reflexes would still be intact and functional. The other options (spoken words, conscious thoughts, and future plans) all involve higher cognitive functions that require intact cerebral cortex and would be severely impaired if the cortex was injured.
