The Flourens concept of the intellect as single unity, claiming equivalence of all brain areas, has long proved untenable. […] However, primary functions alone, can be referred to specific cortical areas. […] The cerebral surface is a mosaic of such primary elements whose properties are determined by their anatomical connections to the body-periphery. All processes which exceed these primary functions (such as synthesis of various perceptions into single concepts and the more complex functions such as thoughts and consciousness) are dependent upon the fiber bundles connecting different areas of the cortex.
