Abstract :
This study adapted the CURRY program and assessed the relationship of the 3-D spike sources to focal lesions evident on MRI scans. The subgroup is selected as it represents an initial step in determining the merit of this technique in the presurgical evaluation of children. Further studies comparing reconstructed spike sources with intracranial electrode recording are planned. CURRY is a software package that provides a variety of methods for accurately localizing the source of electrical activity in the brain. This is achieved by combining EEG and magnetoencephalogram (MEG) signals with structural imaging modalities.
