| Abstract | Method Individual head models for EEG source imaging and tCS targeting are expensive. Instead, we propose a highly detailed FEM of the ICBM152 head, named as ICBM-NY. We approximate 4 individual heads and measure localization and targeting errors. Our model compares favorably to individual and individualized models. All data are made available online.
