| Baillarger of France, initially studied medicine in Paris under Esquirol devoting his time chiefly to the management of the mentally ill. Outstanding in his work in psychiatry was that on hallucinations and on the hypnagogic state. But in 1840 while engaged in clinicopathological correlations with simple methodology he was able to demonstrate the "external line or the white stripe of Baillarger", and to show that the cortex was made up of layers or "laminations". He also demonstrated the surface of the human brain in comparison to its own volume is less than that in smaller animals. | ![]() |
