(838-870 AD)

Ali Bin Saleh al-Tabari wrote a seven volume book “Firdaws al-Hikma”, (Garden of Wisdom). The fourth volume of the collection was devoted to brain disorders. He wrote on epilepsy, memory loss, hypersomnia, tinnitus, and headache. He differentiated migraine (al Shaqiqa) from other headaches, tetanus, and stroke.
Divided the brain into three functional areas: anterior for imagination, middle for rationality, and posterior for memory.

Only two copies of the book are left. The complete copy is in the British Museum, the other, an abridged copy, is in the Berlin Museum.
