Brain: structures seen from the lateral view (preview) - Human Neuroanatomy | Kenhub

The gross anatomy of the human brain can vary, but since the development of the brain is strictly coded by genes, many of the notable structures have an uniformed appearance and are the same in the brain of every human being. These structures are in the form of the gyri and sulci, and the way they are positioned to each other defines the names they carry.

The cerebral cortex, which is the area of the cerebrum seen at a lateral view of the brain, is about 2-5 mm thick and accounts for about 80% of the brain’s totalling mass. Its total area has been estimated to be about 2000 cm². It is thrown into a complicated series of tortuous folds, the gyri (singular: gyrus) and between these gyri are grooves or indentations called sulci (singular: sulcus).

The highest level of cognitive functions and information processing takes place in the cerebral cortex. Some functions of the cerebral cortex include thinking and reasoning, memory, consciousness, attention, perceptual awareness and language.

In the full version of this tutorial, we will cover the following topics:
- lobes, sulci and gyri seen from the the lateral views of the brain.
