The ridges and furrows in the cerebral cortex are actually folds. The 'furrows' are called sulci and the 'bumps' are called gyri.

What increases the surface area?

This only applies to larger mammals. The cerebral cortex is folded into many gyri (ridges) and sulci (furrows), which has allowed the cortex to expand in surface area without taking up much greater volume.

What are the folds in the cerebral cortex called?

The folds in the cerebral cortex are called sulci (singular: sulcus) and gyri (singular: gyrus). Sulci are the grooves or furrows, while gyri are the ridges or bumps on the brain's surface. These folds increase the surface area of the brain, allowing for more neurons to be packed within the limited space of the skull.


What part of the brain has ridges and grooves on it?

The ridges and grooves on the brain are found on the cerebral cortex, which is the outermost layer of the brain. These ridges and grooves are known as gyri (ridges) and sulci (grooves), and they increase the surface area of the brain, allowing for more neural connections and processing power.

What are the inwards folds of cerebral tissue?

The inward folds of cerebral tissue are known as sulci. They are grooves or furrows that separate the gyri, which are the raised folds of the cerebral cortex. Sulci increase the surface area of the brain, allowing for more complex functions to be carried out.
