Gyri

From WikiMD's Wellnesspedia

Gyri are ridges on the brain's surface, separated by grooves known as sulci. They are a significant part of the cerebral cortex, which is responsible for higher brain functions such as thought, language, and memory.

Anatomy[edit | edit source]

Gyri are part of the cerebral cortex, the outermost layer of the brain. The cortex is divided into four main regions or lobes: the frontal lobe, parietal lobe, temporal lobe, and occipital lobe. Each of these lobes contains different gyri that are associated with different functions.

Function[edit | edit source]

The gyri increase the surface area of the brain, allowing for higher function and thought. Each gyrus is associated with different functions, depending on its location in the brain. For example, the precentral gyrus is involved in motor control, while the postcentral gyrus is involved in sensory information processing.

Clinical significance[edit | edit source]

Abnormalities in the gyri can lead to various neurological conditions. For example, polymicrogyria is a condition where the brain has too many small gyri, leading to intellectual disability and seizures. On the other hand, lissencephaly is a condition where the brain has fewer gyri, leading to severe developmental delays.
