At SSI, we provide the most advanced,
powerful, and useable software tools to measure, describe, and visualize
human brain dynamics, for use by researchers and clinicians worldwide.
Founded in 1990 by Richard E. Greenblatt, PhD., Source Signal Imaging
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.
Conventional neuroimaging (for example
magnetic resonance imaging, or MRI) can answer the where question, but not
the when question. Electroencephalography (EEG) and the closely allied
Event-Related Potentials (ERP's) can tell you 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. We call this process multimodal dynamic
functional brain imaging or source estimation.
Our principal product is EMSEŽ Suite, a
software toolkit consisting of 6 modules. The modules may be purchased
separately, or as a bundle. Taken together, EMSEŽ 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). EMSEŽ Suite runs under the Microsoft Windows family
of operating systems as well as Linux, on Intel- compatible processors.
