Cerebral hemispheres (overview)

The brain can be divided into left and right cerebral hemispheres.

Each cerebral hemisphere is divided into six sections, called "lobes": frontal lobe, parietal lobe, temporal and occipital lobe; plus two other that are not visible from outside: Insula and limbic lobe.

To locate these different lobes of the brain, a 3D reconstruction was made​ from a MRI exam of the head. The skull was removed using scissors provided by software (image processing).
