Straight gyrus
(Redirected from Gyrus rectus)
Straight gyrus
The Straight gyrus (also known as the rectus gyrus or gyrus rectus) is a part of the brain located in the frontal lobe. It is the most medial, or innermost, part of the orbital gyri, which are a collection of gyri located on the inferior surface of the frontal lobe. The straight gyrus is involved in various cognitive functions, including emotion and memory.
Etymology[edit | edit source]
The term "gyrus" comes from the Greek word for "circle" and is used in anatomy to describe the folds of the brain. The term "straight" in "straight gyrus" refers to the relatively straight-forward course this gyrus takes compared to the more complex, curved paths of other gyri.
Anatomy[edit | edit source]
The straight gyrus is located on the medial surface of the orbital part of frontal lobe, just above the olfactory sulcus. It is bounded laterally by the olfactory tract and medially by the longitudinal fissure, which separates the two hemispheres of the brain.
Function[edit | edit source]
The straight gyrus is involved in several cognitive functions. It plays a role in the processing of emotion, particularly negative emotions such as fear and sadness. It is also involved in memory, particularly the formation of long-term memories.
Clinical significance[edit | edit source]
Damage to the straight gyrus can result in a variety of neurological and psychiatric conditions. These include mood disorders such as depression and anxiety, as well as cognitive disorders such as amnesia.
