Askiitians Tutor Team
The ridges and grooves on the surface of the human brain are called gyri (singular: gyrus) and sulci (singular: sulcus), respectively. Gyri are the raised, convoluted parts of the brain's cortex, while sulci are the shallow grooves that separate the gyri from each other. These features increase the surface area of the brain, allowing for a greater number of neurons and connections within a confined space. The folding of the brain's surface also plays a crucial role in cognitive function and information processing.
