| Abstract: | Improvements in computational efficiency are bringing the realization of real-time imaging of the dynamic behavior of neural activity in the human brain a step forward. Estimating the location, distribution and time-variation of the current sources that produce an observed electroencephalogram (EEG) has been shown to be significantly improved by using a realistic head model. The calculations involved are however several orders of magnitude larger than the simpler spherical head models. We describe a computational time improvement in calculating the forward gain matrix required for the associated inverse problem, based on solving the forward problem for monopoles rather than dipoles. |
