No, not at all.
Simply, the furrows on the surface of the brain between the gyri.
Gyri are the folds in the brain that store memories. These are located on the cerebral cortex, along with the sulci.
The brain. Sulci are the valleys, gyri are the hills when looking at the surface anatomy
They are called sulci and they allow for a greater surface area of the cortex of the brain which is where the majority of the neurons reside.
Prominent sulci and gyri indicate increased folding and convolution of the brain, which can be normal in young individuals with healthy brain development. However, if prominent sulci are present along with both Sylvian fissures being prominent, it may suggest brain atrophy or a medical condition affecting the brain's structure. Further evaluation by a healthcare professional may be needed to determine the underlying cause.

The cerebrum
The hills in the surface of the brain are called gyri (singular: gyrus), and the valleys are called sulci (singular: sulcus). Very deep sulci are called fissures. When locations are described in the brain, major sulci and gyri are often used as reference points, like familiar landmarks.Source: Sparknotes
The brain is covered in ridges (gyri) ans grooves (sulci).
Simply, the furrows on the surface of the brain between the gyri.
The infoldings of the brain are the sulci, and the outward foldings are the gyri.
They are called sulci (plural of sulcus).
As the ventricles enlarge with CSF under pressure, the brain is squeezed with the result that the gyri come together…emptying the subarachnoid spaces (sulci) of CSF. Refers to condition of not being able to visualize sulci on CT.
The "squiggly" appearance of the brain refers to the sulci and gyri the comprise the cerebral cortex. The sulci are the valleys, or sunken portions, and the gyri are the raised portions. The "squiggly" convolutions of the cerebrum (brain) allow for more surface area. Thus, the contours of the brain help increase the overall volume of the brain inside its limited space, the cranium.

Parts of the Brain: Cerebrum-largest part of brain, 7/8 total mass of the brain. * 2 cerebral hemispheres: # ridges- gyri # grooves- sulci *Gyrus(gyri)-is a ridge on the cerebral cortex. Folds on the brain material. Many ridgescalled convolutions, or gyri, or gyrus, separated by grooves, mark the cerebrum's surface. *Sulcus(sulci)-shallow grooves on the brain. Generally, a shallow to somewhat deep groove is called a sulcus, or sulci, and a very deep groove is called a fissure.
a sulcus is a depression or a groove found on the surface of an organ or tissue,as on the surface of the brain separating adjacent convultion. While a gyrus is one of the prominent rounded elevations between the sulci or grooves on the surface of the hemispheres of the brain.
