N2 - In this work we inspect and validate the back-projection cortical potential imaging (BP-CPI) technique. The BP-CPI is a relatively new tool which estimates highly detailed cortical potential distributions from the smeared measured EEG spatial signals. The testing of this tool includes the study of the BP-CPI sensitivity to real-life interferences and errors, such as electrodes noise, displacement errors, and the number of electrodes. This was done through a series of computer simulations (performed using Sim4Life by ZMT) solving scalp and cortical potential distributions excited by three source configurations. Examining the results in this sensitivity study, it is clear that the BP-CPI technique provides a useful tool for recovering the cortical potential underlying within the subject head.
