Stereotaxy is a neurosurgical technique which consists in using the co-ordinates obtained by placing electrodes in a patient's brain to map in precise detail the part of the brain causing a particular disease, providing the neurosurgeon with the detailed information required for a more targeted surgical intervention. This book first provides background information on stereotaxy, discussing the methods and techniques used in stereotaxy applied to epilepsy surgery. Its many illustrations of surgical interventions and of the materials and methods used when implanting the electrodes give the reader a very clear view of the sequence of events involved. This is a true guide to stereotaxy and neurosurgery. Contents : Part I. Investigation methods Part II. Stereotaxy and implantation techniques Part III. Epilepsy surgery
