EGI's Clinical Newsletter Summer 2012: bringing you the latest product and event information.
From Startup to International Company
EGI is celebrating 20 years since our founding in May 1992. We’ve come a long way in 20 years. When EGI first started, 64 channels was considered extremely dense array EEG. Now, 128- to 256-channel EEG is routine for researchers and clinicians on the cutting edge of brain research, neurology, and neurosurgery.
The original Geodesic Sensor Nets were such a novel idea, that they looked like something out of a science fiction movie and were sewn together with needle and thread. Now, they are manufactured using state-of-the-art technology and represent the easiest to use and most comfortable electrode placement system on the market. Similarly, EGI's amplifiers and software have improved dramatically, and now support multimodal imaging, source estimation, and more. Complete EEG systems are now available for both research and clinical use.

Report on dEEG for Epilepsy Surgery
New publication compares dEEG and intracranial EEG
Dr. Yamazaki and colleagues, from Seirei Hamamatsu General Hospital, have published an important study evaluating the clinical utility of scalp dense array EEG (dEEG) for use in epilepsy presurgical planning. This is the first study to compare dEEG directly with simultaneous intracranial EEG (icEEG), considered the most accurate method of confirming the seizure onset zone in the brain.
Epilepsy patients with disabling seizures that cannot be controlled by drugs are candidates for a surgery that removes the part of the brain responsible for the seizures. Typically, scalp EEG is used to localize the area of the seizure onset. To validate that the location is correct, intracranial electrodes are then placed directly on that area of the brain for an intracranial EEG (icEEG). Incorrect placement of the intracranial electrodes would result in subsequent surgeries to move the electrodes, so it is vital that the scalp EEG provide the most accurate localization of the seizure source possible. Advances in dense array EEG and source estimation algorithms hold the promise for providing much better localization of the seizure onset zone compared to conventional EEG.
The authors conclude that 256-channel dEEG represents a significant improvement over conventional EEG in guiding placement of icEEG electrodes. Thus, use of high-channel scalp dEEG may be clinically useful for presurgical planning.

dEEG CME Course for Clinical Applications
Interpretation and Clinical Applications of Dense Array EEG: A Practical Workshop
26–27 October 2012
Village of Dexter, Michigan, USA
As a result of workshop attendance, participants will gain practical knowledge and skills for reading, interpreting, and reporting dEEG studies and creating a dEEG clinical service.
Topics will include
- the basic science of dEEG
- concepts of dipole modeling and source localization
- introduction to Net Station software clinical applications of dEEG in office-based and hospital settings
- hands-on sessions for reading dEEG compared to conventional EEG
- common pitfalls, generating useful reports, and case studies
More information, including CME accreditation information.
Advanced EEG Symposium
Clinical Applications of Advanced EEG — Developments in EEG/fMRI and High Resolution EEG of Epilepsy
European Congress on Epilepsy
ICC London ExCel, Hall C
Wednesday, 3 October 2012
8 am – 9 am
Aim of the Symposium
The symposium will cover recent work applying dense array EEG (dEEG) and EEG/fMRI to epilepsy diagnosis and the localization of the epileptic foci. The focus of the session will be practical in nature, focusing on the clinical implications of recent work, rather than on theoretical concepts. All talks will focus on work done with epileptic patients.

New Sensor Nets Better Than Ever
Available for routine, LTM, and MR environments
In July 2011, EGI launched a new Net design, the HydroCel Geodesic Sensor Net (HCGSN) 130. This new design provides the same sensor layout and electrode performance as the earlier HCGSN 120, but has improved mechanical strength, with special attention to the wire-electrode interface. Customers find the new design faster to use, with less worry about wire breakage while applying the Net. The new Net design is available for order in all sizes and channel counts.
In May 2012, we launched the HCGSN 220 MR, extending the new design to Nets for the MR environment. The HCGSN 220 MR have an equivalent sensor layout and electrode performance as the previous HCGSN 210 MR products, but the same, more robust mechanical design as the HCGSN 130. All customers ordering new MR Nets will receive the new HCGSN 220 MR product with new product numbers.
