Detailed explanation-1: -What is the cerebral cortex? Your cerebral cortex is the outermost layer of your brain. Its surface has many folds, giving it a wrinkled appearance. The folds consist of many deep grooves called sulci and raised areas called gyri.

Detailed explanation-2: -The folds of a brain are called gyri and the grooves are called sulci.

Detailed explanation-3: -For more than 50 years, researchers have tried to understand why brain folding-development of the characteristic wrinkles of the cerebral cortex-occurs.

Detailed explanation-4: -The cerebral cortex, which is the outer surface of the brain, is associated with higher level processes such as consciousness, thought, emotion, reasoning, language, and memory. Each cerebral hemisphere can be subdivided into four lobes, each associated with different functions.

Detailed explanation-5: -Why do our brains have wrinkles? The simple answer is to make them more efficient. Scientists think that as we evolved and our cortexes expanded, our brains created folds to optimize how much brain matter could fit into our skulls.
