We demonstrate the use of Spatial Filtering in EIT (EIT-SF) to estimate the time course and position of localized conductivity changes in the brain, when modelling ischemic stroke and neuronal activation. We compare the solutions obtained for three head models. Results support the use of EIT-SF to localize and characterize dynamic conductivity changes in the human brain.
