Source Signal Imaging (SSI) specializes in multimodal source estimation techniques, enabling the researcher to combine EEG and MRI datasets to better answer where things are happening in the brain, and when things change. SSI, provides advanced, powerful, and useable software tools to measure, describe, and visualize human brain dynamics, for use by researchers and clinicians worldwide. Conventional neuroimaging (e.g. MRI) can answer the 'where' question, but not the 'when 'question. Electroencephalography (EEG) and the closely allied Event-Related Potentials (ERP's) can tell 'when' something happened with an accuracy of thousandths of a second, but isn't very good at the where questions. Source Signal Imaging, Inc. (SSI) develops and markets software that combines MRI and EEG to answer both when and where in a way that neither method can answer alone - process multimodal dynamic functional brain imaging or source estimation. The firm's principal product is EMSE® Suite, a software toolkit consisting of six modules which may be purchased separately, or as a bundle. Taken together, EMSE® Suite supports the key steps required to combine electrophysiological data (like EEG and MEG) with image data (like CT or MRI) for multimodal dynamic functional imaging. Taken separately, individual modules may be used by customers who wish only a subset of the complete functionality (e.g. EEG time series analysis and display). EMSE® Suite runs under the Microsoft Windows family of operating systems as well as Linux, on Intel- compatible processors
