The CURRY NeuroImaging platform and MEG have a history stretching back over 25 years. CURRY was first conceived as a product in the early 1990’s when Philips Electronics investigated the feasibility of developing it’s own MEG hardware platform. Ultimately, the hardware platform did not survive, but the software, along with its core engineering architects, Dr. Manfred Fuchs & Dr. Michael Wagner, continued on. When Philips exited the MEG business, CURRY and the development team were purchased by Neuroscan. At this time, the UNIX-based CURRY platform appealed more to the research community than to the clinical market. By 1999, publications were emerging describing the application of CURRY for cortical localization of EEG and MEG activity for tactile and auditory sensory input. However, “novel developments” and “new approaches to detailed localization of specific epileptic discharges” as well as identification of functionally critical areas of the brain controlling language and memory using CURRY, were also being reported in the clinical literature. Migration of CURRY from the UNIX to Windows platform in 2003 resulted in a rapid expansion of the use of CURRY in both the research and clinical worlds.
The benefits associated with CURRY’s ability to integrate MEG with EEG and co-register both kinds of high temporal resolution functional imaging data with the structural neuroimaging data including MRI, CT, DTI, as well as PET, SPECT and fMRI accelerated the the adoption of the software by both the research and clinical communities. Early clinical adopters, such as Dr. John Ebersole, supported and championed the benefits of source localization tools such as CURRY, contributing to the development of specific source analysis billing codes for EEG and MEG. For a long time, CURRY has been the de-facto software platform for clinical MEG community, particularly for those assessing epilepsy. This has culminated in the adoption of CURRY as the standard analysis platform by the European E-pilepsy Consortium.
For the CURRY team, integrating CURRY with the KRISS MEG hardware represents a full circle of development. With long-term future development plans for both hardware and software, CURRY MEG will offer an expanding list of benefits based on the first fully integrated platform combining EEG, MEG, multi-modal neuroimage co-registration and source reconstruction from a single provider – Compumedics Neuroscan.

Neuroscan is a company founded by neuroscientists with a primary mission to support the needs of investigators, in both the research and clinical domains. For over 20 years, research and development has remained the primary focus of Neuroscan. From creating the world’s first complete hardware and software package for acquiring and processing EEG and ERP data to developing the industry standard in quality amplifiers, Neuroscan has strived to provide advanced solutions for research on the leading edge of science.
Neuroscan recognizes the importance of providing comprehensive solutions for research. Each component in the Neuroscan family of products integrates seamlessly with the others, allowing the selection of only those tools that meet your current needs, secure in the knowledge that a clear upgrade path exists when your requirements necessitate expansion. From the most basic EEG recordings to sensory, perceptual and cognitive ERPs, from source localization to integration with MRI data or even simultaneous recording with fMRI, the evolution of the Neuroscan product line continues.
Developing solutions that support a wide variety of applications is no small task. Starting with the most basic processing tools that are common to all EEG applications, Neuroscan has not only incorporated these algorithms but has sought to optimize and improve these processes. For instance, eye artifact reduction is a necessary part of all EEG data processing, and Neuroscan provides multiple methods for detection and reduction, with immediate application so you can see which methods work best (using CURRY 7).
Beyond basic data processing, Neuroscan has incorporated an extensive array of analysis tools and is constantly assessing and incorporating the latest processing algorithms to provide the neuroscience community with the most advanced tools for their research. Examples include real time source analysis with generalized boundary and finite element head models, real time independent components analysis and filtering, multiple single and distributed source models, and non-parametric topographical ANOVAs.
One major focus of our ongoing R&D efforts is in the area of functional neuroimaging. Over the years, three separate research groups have merged different areas of expertise to produce true functional neuroimaging integration.
Historically, R&D in the El Paso office of Neuroscan was responsible for the amplifiers and acquisition and analysis software for EEG and ERP systems — SCAN. Real time integration of EEG and fMRI acquisition became the focus of the Neuroscan team about 10 years ago. To facilitate this development, active international collaborations have been established with some of the most advanced fMRI facilities in the world. Ultimately, the combined temporal resolution of EEG and ERPs and spatial accuracy of fMRI will provide neuroscientists with an unprecedented capacity to explore sensory, perceptual and cognitive processes in normal and pathological populations.
Operating in parallel since 2000, when Neuroscan acquired CURRY from Philips, the source reconstruction group in Hamburg, Germany has developed advanced algorithms for segmentation and source reconstruction that have led to the most sophisticated neuroimaging software package in the world — CURRY.
CURRY is used worldwide in a variety of research facilities, and in an increasing number of clinical operations, dealing primarily with epilepsy, where CURRY’s ability to integrate EEG and MEG with the CT, MRI, and other forms of image data provide an insight into the origin of the epileptic activity.
Neuroscan merged with Compumedics in 2003, and there was then a third R&D division, devoted primarily to the development of EEG amplifiers and software systems related to sleep disorders.
In recent years, there has been an inevitable and deliberate integration of the three overlapping R&D divisions, culminating in the CURRY Neuroimaging Suite, or CURRY 7. This suite of modular programs combines the years of software development for EEG acquisition and analysis from SCAN and the Compumedics acquisition software, with the image data analysis and source reconstruction from CURRY. CURRY 7 has been designed to acquire data not only with the Neuroscan amplifiers, but also with the Compumedics amplifiers. Data files from SCAN and from the Compumedics software are all read directly by CURRY 7.
CURRY 7 provides a solid foundation for years of future development in the research world, while also becoming more ensconced in clinical facilities. Because of its modular development, users need only obtain the components required for their current needs. The blend of R&D resources within Compumedics/Neuroscan ensures that the future will see even more functionality, as we continually strive to provide the best and most current capabilities for our users.
