Abstract

This research proposal is centered in the study of refractory mesial temporal lobe epilepsy (MTLE) by high resolution structural MRI, receptor imaging and historadiological correlations. This approach will allow the development of methods for correlating in vivo and ex vivo imaging. Accordingly, we devised three projects that will investigate the basis of MRI signal alteration, serotonin transporters profile detected by molecular imaging and full analysis of brain parenchyma in patients with MTLE. The corresponding projects are histological basis of MRI signal in the temporal lobe (project A), molecular imaging in mesial temporal lobe epilepsy: in vivo and ex vivo quantification of serotonin transporters (project B) and whole brain high resolution mri analysis in patients with refractory mesial temporal lobe epilepsy (project C). The complete versions of projects A, B and C are on appendixes I, II and 3 respectively. The resources (researchers, technicians, imaging equipments) involved in the accomplishment of this proposal will make available to the ClnAPCe network: 1) a multidisciplinary team able to integrate clinical and experimental epileptology, innovative imaging acquisition/processing and advanced histopathological analysis; 2) a state-of-the-art core facility for advanced imaging studies; 3) new methodologies for historadiological correlations; 4) new tools for second order imaging processing; 5) expertise on molecular imaging. These technological and scientific resources are applicable to other important areas of biomedical research (oncology, neurodegenerative and psychiatric diseases) and are designed to be integrated into a network environment sharing knowledge with other centers via e-leaming. This is an essential requirement for the developing of telemedicine, a key tool for research, education and telediagnostic activities. In spite of the importance of epilepsy to public health, the number of researchers and clinically qualified specialists in the related areas of neuroscience remains small. The ClnAPCe network initiative is expected to promote a rapid progress in this field. Consequently, we have the responsibility for disseminating the knowledge generated in the network projects to the medical and scientific communities. For this reason, the main educational emphasis of our program is turned to technology transfer in imaging processing using voxel-based morphometry (VBM), molecular imaging acquisition techniques and neuroimage databasing and data mining. Since epilepsy is a disease that causes generalized anxiety in the public at large, we intend to provide a web site devoted to increase public awareness on the scientific advances achieved by the ClnAPCe projects.
