Respuesta :
Gyri and sulci are the folds and grooves, respectively, which characterize the surface of the human brain.
What is gyri?
- The gyri are part of a network of folds and ridges that help the human brain and other mammalian brains have a larger surface area. The brain's size is limited because it is confined to the skull.
- Ridges and depressions form folds, allowing for a larger cortical surface area and higher cognitive function within the confines of a smaller cranium.
What is sulci?
- The folded surface of the cerebral cortex is made up of sulci, which are grooves, and gyri, which are folds or ridges.
- Fissures are larger or deeper sulci, and the two terms are often used interchangeably.
- In humans and other mammals, the folded cortex increases the surface area of the brain.
- When looking at the human brain, the grooves cover two-thirds of the surface.
- A gyrus is surrounded by a sulcus, which is a shallower groove.
