Straight gyrus
The portion of the inferior frontal lobe immediately adjacent to the longitudinal fissure is named the straight gyrus, and is continuous with the superior frontal gyrus on the medial surface.
A specific function for the straight gyrus has not yet been brought to light; however, in males, greater activation of the straight gyrus within the medial orbitofrontal cortex while observing sexually visual pictures has been strongly linked to HSDD.Additional images
