Intrinsic Optical Imaging Study to Map Neocortical Seizure in Human Epilepsy Patients

NCT00195052 · Status: TERMINATED · Type: OBSERVATIONAL · Enrollment: 34

No results posted yet for this study

Summary

The purpose of this study is to develop a technique for the intraoperative identification of human functional and epileptiform cortex using intrinsic signal imaging. The investigators propose that the ability to optically monitor neuronal activity in a large area of cortex in "real-time" will be a more sensitive and time-saving method than the electrical methods currently available. The applications of this technique will not only theoretically increase the safety and efficacy of many of neurosurgical procedures, but will be useful as an investigational tool to study human cortical physiology.
