For the purposes of EPICURE, the following participating units will be involved:

 

Division of Neurophysiopatology

Silvana Franceschetti, Phone: 39 0223942250, Fax 39 02.70600775; e-mail franceschetti@istituto-besta.it

 

Expertise and current research performed: The Division of Neurophysiopatology of the INNCB includes the Clinical Neurophysiology Laboratories, the Epilepsy Center, a Bioengineering Unit and Laboratories devoted to experimental neurophysiology. The Laboratories of Clinical neurophysiology provide the clinical and technical expertise for all aspects of various neurodiagnostic and testing procedures on patients of various ages and medical conditions. The Epilepsy Center performs long-term EEG monitoring suitable to establish a definite diagnosis in patients with complex form of epilepsy or episodic symptoms of uncertain cause. The Laboratory of bioengineering sets up and applies special techniques of digital signal processing and analysis to be applied for diagnostic support, research purposes and innovative clinical applications. The laboratory research is based on a multidisciplinary approach to nervous diseases, namely epilepsies, combining the expertise of clinical, experimental electrophysiological and molecular biology techniques. The research fields include study of in vitro preparation of cortical structures to evaluate intrinsic excitability changes and epileptogenesis at cellular level underlying neocortical epilepsies and experimental models of genetically determined epilepsies (expression of mutants in cell lines and cultured neurons, and study of gene targeted animal models).

 

Facilities/Equipment: Equipment for electrophysiological recordings of dissociated cells and tissue slices; equipment for molecular biology; Applied Biosystems ABI Prism 3100 sequencer: culture room with sterile hoods and incubators; confocal Microscope and equipment for live cell imaging; animal facility: operating room with equipment for stereotaxic surgery and injections.

Expertise and current research performed: the Epilepsy Clinic and Experimental Neurophysiology Unit of INNCB is internationally recognized as a centre of excellence for the studies of the basic mechanisms of neurological diseases. The unit is devoted to study epilepsies from bench to bad side and particularly addressed to investigate the pathogenesis and physiopathology of epileptogenic malformations of cortical development in human and animal models. Five dedicated beds for epileptic patients (two equipped for prolonged Video-EEG monitoring), fully equipped laboratories for neuroanatomy and experimental neurophysiology are part of the unit. The unit is operating at clinical and research level in synergy with the Epilepsy Surgery Centre at the Niguarda Hospital in Milan. The unit is currently involved in the following research projects: 1) diagnostic pre-surgical assessment and surgical guidelines for drug resistant epileptic patients candidates for epilepsy surgery (leader of a multicenter Italian group supported by the National Ministry of Health); 2) Mesial temporal lobe epilepsy with and without hippocampal sclerosis: electroclinical features, prognosis and pathogenetic mechanisms (supported by Italian Ministry of research); 3) Role of gap junctions in infantile epilepsy and disorders of cortical development (leader of a multicenter project sponsored by Mariani Foundation). The unit is also involved in identification, classification and morphofunctional correlations of malformations of cortical development in epileptic patients
