The thick folds on the surface of the cerebrum are called gyri (singular: gyrus), while the grooves that lie between these folds are referred to as sulci (singular: sulcus). The presence of gyri and sulci increases the surface area of the brain, allowing for a greater number of neurons and improved cognitive functions. This intricate structure is essential for various brain functions, including control of movement, sensory processing, and higher-order thinking. Understanding these anatomical features is crucial in fields such as neuroscience and psychology, where they are often studied to comprehend brain function and associated disorders.
