Frontal __; brain section

I believe the answer is:

lobe

(Other definitions for lobe that I've seen before include "Fleshy part of the ear (4)" , "Rounded projection of a larger structure" , "Bottom part of ear" , "Piece of ear" , "Division of the lungs or brain" .)

I've seen this clue in The Mirror.
