olfactory sulcus (olfs)
The term olfactory sulcus refers to a superficial feature of the frontal lobe. Defined by dissection it is a deep groove on the ventral surface that overlies the main olfactory bulb and and olfactory tract. It separates the straight gyrus on the medial margin of the lobe from the medial orbital gyrus. It is found in the human ( Mai-1997 ) and the macaque ( Martin-2000 ). An equivalent structure does not appear in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).
