Straight gyrus
The portion of the inferior frontal lobe immediately adjacent to the longitudinal fissure (and medial to the medial orbital gyrus and olfactory tract) is named the straight gyrus,(or gyrus rectus) 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 (hypoactive sexual desire disorder).[1]

gollark: I can anecdotally confirm that my Intel Dual Band Wireless-AC 7265 or whatever the stupidly long brand name is works very well under Linux. Except for some random dropouts which were fixed when I switched NetworkManager to using `iwd` instead of `wpa_supplicant`.
gollark: Without computers lots of stuff will break. If you consider microcontrollers to be computers that is. Otherwise somewhat less stuff.
gollark: The designs for computers and computer bits are all stored on computers.
gollark: Without computers, transport and global supply chains will fail.
gollark: All the tooling for making computers... uses computers.
