This volume is devoted to a particular facet of infantile epilepsy, Occipital Seizures and Epilepsies. That an epileptogenic process common to all ages manifests itself differently according to the stages of cerebral evolution suggests that a deeper investigation of these age-dependent epilepsies and their related conditions is necessary. Findings of basic sciences in epileptogenicity are compared with clinical data and developed towards practical applications of general interest, such as the fundamental differential diagnosis between occipital seizures and migrainous attacks. Since the normal maturation of the brain in the post-natal period largely depends on early sensory-motor experience, particularly visual functions, it is essential to consider research maturation of visual systems, as it may offer stimulating insights into the peculiarities of these 'epileptic syndromes' which represent a model for the study of the child's epilepsy. Though dealing with a particular problem in paediatric neurology, they point to a general process in human biology.
