Abstract

In the present study we evaluate the performance of several inverse algorithms for reconstructing the cortical current density distributions from scalp EEG recordings. The direct cortical SEP recordings in a patient were used as a gold standard to assess the performance of the numerical algorithms. The present results suggest that L₁-norm methods gave the most accurate results in terms of cortical current density imaging of brain responses invoked by somatosensory stimulation
