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.
Now and Into the Future
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.
