What is a "gyrus"?

A gyrus is a prominent fold or ridge on the surface of the cerebral cortex. It is a raised, convoluted structure that plays a crucial role in the processing and integration of sensory information, motor control, and cognitive functions. The gyri increase the surface area of the brain, allowing for more complex neural connections and higher-order processing. They are an essential component of the intricate structure and functionality of the brain.
