A person who believes in or practices cerebralism; someone who emphasizes the brain's role in thought and behavior.
From cerebralism plus -ist (one who practices or believes). A 19th-century term for philosophers and scientists who centered brain function in their theories.
A cerebralist was essentially saying 'the brain explains everything about who you are'—a radical idea that challenged centuries of thinking that emphasized the heart, soul, or divine inspiration.
