In the Brain Areas section you can learn about what kind of brain functions are associated with each major cortical lobe of the human brain. The cortex is the thin layer of wrinkly brain tissue on the outer surface of the brain that is highly evolved in humans. It is the part of the brain that is detected using EEG. In Brain Viz you will learn about the key functions of the four main lobes: the Frontal, Parietal, Temporal and Occipital Lobes.
