From "The Self and the Imperative" - The Writings of Sigmund Freud, Volume IV, Selected Essays III, Dvir Publishing, p. 148
"The self is, after all, a physical essence. It is not an essence only on the surface, but is itself a projection of the surface. If you want to find an anatomical parallel to this vision - you can only identify it with the "brain dwarf" of the anatomists, which stands on its head inside the cerebral cortex , stretches his heels upwards, looks back and carries, as is known, the speech area on his left".
