This is preliminary and not tested. The best way to test these would be to give a bunch of people certain tasks pertaining to each of the possible functions, while monitoring their brain activity. For example solving a math equation (-Ti), or watching a highly emotional movie (+Fe , +Fi).

-Frontal lobes: +Ti (left lobe), +Fi (right lobe), -Te (left lobe), -Fe (right lobe), +Se (both), +Ne (both),
-Parietal lobes: -Fi, +Fe
-Temporal lobes: -Ne, +Ni, -Si , -Ni, -Ti, +Te
-Occipital lobe: -Se, +Si
Analysis: On first view, it seems unbalanced that the frontal lobes perform so many tasks in contrast to the other lobes, but as evidence we have the instances were a person has suffered damage to their frontal lobes (or a lobotomy) and there have been major changes to their personality.
