Thanks to advanced imaging techniques, it is now possible to recognise in vivo structural alterations of the cortex leading in many patients to epileptic syndromes, frequently resistant to pharmacological treatment. Areas analysed in this book are: mechanisms of cortical development; animal models of neuronal migration disorders mimicking human pathology; electroclinical, neuroradiological and neuropathological studies of the different forms of cortical dysplasia. This volume includes contributions from neurologists, epileptologists, neuropaediatricians as well as paediatricians and neuroscientists, stimulating a multidisciplinary discussion to improve diagnostic and therapeutic strategies.
