The elevated ridges of tissue on the cerebrum are called gyri. These structures are an important part of the brain’s anatomy and play a significant role in its overall function.
Gyri are formed by the folding of the cerebral cortex, which is the outer layer of the brain. This folding increases the surface area of the brain, allowing for more neurons and enhanced cognitive abilities. The valleys between the gyri are known as sulci. Together, gyri and sulci create the characteristic wrinkled appearance of the brain.
Each gyrus is associated with different functions, such as sensory perception, motor control, and higher cognitive processes. Understanding these structures is crucial for studying how the brain works and how various functions are localized within it.
