From the Research

The gyrus recti is a critical brain region involved in various cognitive processes, including decision-making, emotional processing, and aspects of executive function, and its damage can result in significant morbidity and impaired quality of life. The gyrus recti is a small, straight gyrus located on the orbital surface of the frontal lobe of the brain, running parallel to the longitudinal fissure and sitting medial to the olfactory sulcus. This gyrus is part of Brodmann area 11, which belongs to the prefrontal cortex. Functionally, the gyrus recti has connections to the limbic system and plays a role in processing olfactory information due to its proximity to the olfactory tract.

Some key points to consider about the gyrus recti include:

  • Its involvement in cognitive processes such as decision-making and emotional processing 1
  • Its connection to the limbic system and role in processing olfactory information
  • The potential consequences of damage to this area, including personality changes, emotional dysregulation, and impaired decision-making abilities
  • The blood supply to the gyrus recti, which is primarily from branches of the anterior cerebral artery

It is essential to note that the provided evidence does not directly discuss the gyrus recti, but rather focuses on frontotemporal dementia and other related topics. However, based on general medical knowledge, the gyrus recti is an important region that requires careful consideration in the context of neurodegenerative diseases and cognitive disorders. The most recent and highest quality study that provides relevant information on brain anatomy and function is 1, which discusses the angular gyrus and its association with higher order cognitive functions.
