Cephalocentric hypothesis
The cephalocentric hypothesis, also called cephalocentrism, encephalocentrism or cerebrocentrism, is the doctrine that the brain is the seat of the mind, consciousness, sensation and cognition. The position was developed in Ancient Greece from the early fifth century BCE and stood in opposition to the cardiocentric hypothesis, which located those faculties in the heart.
