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] This article incorporates text in the public domain from page 822 of the 20th edition of Gray's Anatomy (1918)This neuroanatomy article is a stub.You can help Wikipedia by expanding it.
