BESA Research 6.1 brings two major novelties to the Source Imaging table which combine to bring focal, reliable, and comparable source images:
Cortical LORETA and CLARA use the individual cortex as source space for LORETA and CLARA analysis. Computing the Laplace operator directly on the surface mesh greatly enhances the specificity of these methods. Combine this with the newly implemented age-appropriate template FEM head models , derived by non-linear averaging across real brains in narrow age-ranges from infancy to adulthood, and you get the additional benefit of realistic head models without the need for MRI imaging or sensor co-registration, and compatibility across all your data sets in group studies. See more information about these head models on http://www.besa.de/products/besa-research/features/head-model-selection/.
Of course there are more new features large and small, such as new source montages for resting state networks, displaying up to one hour of data on one screen, and improved handling of available FFT bands. The full list as a pdf link as well as the setup is available here: https://www.besa.de/downloads/besa-research/besa-research-6-1/.
