Preface. In memoriam Frank Morrell 1926-1996 (F.Torres). List of Contributors. 1. Brain stimulation combined with electrocorticography in the surgery of epilepsy: historical highlights (W. Feindel). 2. Electrocorticography. Historical comments on its development and the evolution of its practical applications (C. Ajmone-Marsan). 3. Role of ECoG in "en bloc" temporal lobe resection: the Maudsley experience (C.D. Binnie, G. Alarcon, R.D.C. Elwes, J.J. Garcia Seoane, J. Juler, C.E. Polkey). 4. Role of the ECoG in tailored temporal lobe resection: the University of Washington experience (G.-E. Chatrian, M.-L. Tsai, N.R. Temkin, M.D. Holmes, F. Pauri, G.A. Ojemann). 5. ECoG findings in extratemporal epilepsy: the MNI experience (L.F. Quesney, R. Wennberg, A. Olivier, T. Rasmussen). 6. Chronic electrocorticography: Cleveland Clinic experience (D.S. Dinner, H.O. Luders, G. Klem). 7. Pharmacological activation (G.D. Cascino). 8. The significance of electrocorticographic findings in focal cortical dysplasia: a review of their clinical, electrophysiological and neurochemical characteristics (F. Dubeau, A. Palmini, D. Fish, M. Avoli, A. Gambardella, R. Spreafico, F. Andermann). 9. Post-excision residual spiking after frontal lobe removal: outcome (R. Wennberg, F. Quesney, A. Olivier, T. Rasmussen). 10. Increased neocortical spiking and surgical outcome after selective amygdalo-hippocampectomy (R.A. Wennberg, L.F. Quesney, F. Dubeau, A. Olivier). 11. Direct intraoperative recordings from the hippocampal formation: relation with quantitative volumetric MRI (F. Morrell#, L. De Toledo-Morrell, M.P. Sullivan, D. Bergen, A.M. Kanner, S.J.C. Pierre-Louis, A. Gil-Nagel, R. Ristanovic, M.C. Smith, W.W. Whisler). 12. Correlation between mesial temporal and temporal neocortical interictal spiking in acute ECoG and chronic depth electrode recordings (R.A. Wennberg, L.F. Quesney, A. Olivier). 13. ECoG findings in hemispherectomy (R. Wennberg, L.F. Quesney, J.-G. Villemure). 14. Applications of image-guided surgery to in
