Relating to or characterized by cerebroton ia; describing a personality type supposedly linked to intellectual or thin-bodied constitution.
From cerebrotonia (brain-dominated personality) and -ic (adjective suffix). This was part of Sheldon's mid-20th century theory that attempted to classify people by somatotype and psychology.
Cerebrotonic people were supposedly introverted intellectuals in Sheldon's system, but science has moved far beyond these body-type theories—they're a reminder of outdated thinking.
