1909 C. U. A. Kappers in Arch. Neurol. & Psychiatry 4 162 Just as in the pallium there can be distinguished three territories according to the connections which they exhibit, so the cortical structures occurring in them should be distinguished, according to the same principle, into a palæo-cortex, archi-cortex and neo-cortex.
