What was Hippocrates phrenology of individuals with head injury?

Hippocrates, the ancient Greek physician, did not practice phrenology as it is understood today; that concept arose in the 19th century with Franz Joseph Gall. However, Hippocrates did emphasize the importance of the brain and its role in mental functions, suggesting that head injuries could impact an individual's behavior and personality. He believed that the state of the brain was closely linked to health and illness, indicating an early understanding of the relationship between physical injury and psychological effects.
