Galen expanded on the humoral theory, linking imbalances to brain disorders.

When: 200 AD.

Where: Roman Empire.

Context: This theory shaped early neurology by connecting mental health to physiological imbalances, such as "black bile" leading to melancholy. Source 1: https://www.nlm.nih.gov/exhibition/shakespeare-and-the-four-humors/index.html

Galen’s Influence on Brain Localization

josephzhao675 — 2025-01-20 21:55:14 UTC

Galen identified specific brain regions and connected them to bodily functions, such as movement and cognition.

When: 200 AD.

Where: Roman Empire.

Context: Galen’s ideas about brain localization influenced later theories, including those of the ventricles' role in cognition and sensation.
