[Radioanatomy of the cerebral cortex. Practical guide of identification]

Cerebral sulci identification process is based on several formal rules: it consists a series of steps allowing the identification of the major sulci. The process may be variable for each of us and we propose to read the images in certain order starting with the frontal lobe and its superior frontal gyrus than precentral and central gyri followed by the lateral fissure. Then the insular, lateral parietal and medial hemispheric regions. Finally the major sulci within the temporal and occipital lobes are described in the frontal plane. This presentation indicates the principal rules of cerebral lobes'identification, the basis of variability perception and the localization of small lesions allowing an accurate correlation with clinical findings and a suitable therapeutic procedure.
