A Review of Electrical Source Imaging

Improved source-imaging algorithms increase accuracy of source localization
It has been argued that traditional trace analysis of the EEG only provides a fraction of the information that is available in the signal. With the advent of digitally recorded EEG, advanced analysis of the signals with modern signal processing tools is possible, allowing for much higher accuracy in focus localization. One such approach to electrical source imaging, sometimes called ESI, is the ESIreconstruction of the electrically active areas in the brain based on the surface recordings. Since the introduction of electromagnetic source localization methods, many groups have demonstrated the usefulness of source imaging for localizing the epileptic foci based on EEG or MEG data.

Electrical source imaging has dramatically advanced in recent years. Read the full article for a complete review of recent literature.

Dense Array EEG in the Clinic

The CNNHThe CNNH provides advanced care for patients
Serving an ever-growing outpatient community, the Center for Neurological and Neurodevelopmental Health (the CNNH), located in Gibbsboro, New Jersey, provides neurological and neurodevelopmental diagnostic and treatment services for pediatric patients. Patients at the CNNH include children with neurodevelopmental disabilities, neurobehavioral and neuropsychiatric disorders, brain injury, and other neurological problems. Led by Mark Mintz, MD, the CNNH provides advanced noninvasive techniques for assessing brain function in an outpatient setting.

Read the full article to find out how dense array EEG provides higher accuracy of data as well as a more relaxed patient experience.

Dr. Mintz teaches a course on the use of advanced EEG in a clinical setting. Read the article in this newsletter describing the most recent EEG Readers Course.

EGI Symposium at IEC in RomeIEC

"Advanced EEG… The Clinical Contribution"
EGI is honored to sponsor an upcoming symposium featuring prominent neurologists and neurosurgeons who specialize in EEG and epilepsy. Please join us this August at the 29th International Epilepsy Congress in Rome, Italy. The symposium focuses on advanced EEG for presurgical planning and will be held on Wednesday, August 31, 2011, 7:30 am-9:00 am in Hall Five of the Rome Marriott Park Hotel. A light buffet breakfast will be served. 

This symposium, chaired by Dr. Paolo Manganotti (University of Verona, Italy), will explore recent efforts to apply advanced EEG methods, such as noninvasive EEG source estimation, to improve the presurgical planning process.

For the estimated 30% of epileptic patients who do not respond to antiepileptic drugs (AEDs), epilepsy surgery has long been a critical and potentially curative therapeutic option. Epilepsy surgery success rates have risen significantly in recent years, with some groups reporting success rates as high as 65−85%, depending on the patient population. However, efficient patient selection and careful presurgical workup remain an acknowledged essential element for surgical success. The symposium program includes:

  • Applying Electrical Source Imaging (ESI) in Presurgical Planning - Margitta Seeck, MD, University Hospital of Geneva, Switzerland
  • Comparison of Source Localization Results from Dense Array EEG, IC Electrodes, Depth Electrodes and Traditional EEG - Takamichi Yamamoto, MD, Seirei Hamamatsu General Hospital, Japan
  • The Role of Dense Array EEG in the Presurgical Evaluation - Mark D Holmes, MD, Harborview Medical Center, USA

The focus of the session will be practical in nature, focusing on clinical experience with advanced EEG methods, rather than on theoretical concepts. All talks will focus on experience with epileptic patients.

Online registration is now open. | For additional information, email Workshops.

Net Station 4.5 Software Upgrade

New software upgrades make dense array EEG more accessibleNet Station
EGI is committed to bringing dense array EEG (dEEG) technology to clinicians with the tools they need to increase workflow efficiency and improve patient care. The new upgrades to the Net Station software make this cutting-edge technology more accurate, easier to use, and more accessible than ever. Net Station 4.5 drives the acquisition, review, and analysis of dEEG data, allowing clinics and hospitals to provide their communities with the most advanced EEG technologies. Dense array EEG provides improved accuracy in many areas of neuroscience. See the article on the CNNH for an example of how care centers are using dense array EEG to better serve their communities.

EEG Readers Course

Reasers CourseNeurologist leads dEEG training
In June, the Center for Neurological and Neurodevelopmental Health (the CNNH) in Gibbsboro, New Jersey, together with EGI, hosted an EEG Readers Course for clinicians. The Mintz group at the CNNH has acquired over 1900 dense array EEG (dEEG) recordings from pediatric patients over the last five years, 40% of those on patients with autism spectrum disorder (ASD). The two-day course presented talks on acquiring and analyzing dEEG data, and created a venue for clinicians to learn best practices from each other. Congratulations to Dr. Mintz and the staff at the CNNH for providing an open forum to discuss and debate how dEEG can impact patient care.

The workshop featured topics ranging from basic dEEG theory to the different possible applications of clinical dEEG. In addition, there were discussions of case studies illustrating how dEEG can change clinical practice and how care is given. Some of the discussion topics included how dEEG improves accuracy of source localization, identification of artifacts, and treatment of underserved populations.

If you are interested in attending an EEG Readers Course, please send an inquiry to This e-mail address is being protected from spambots. You need JavaScript enabled to view it . For those who could not attend the first event, we hope that the CNNH will offer another course prior to the AES annual meeting in December. We plan to offer EEG Readers courses throughout the year in various locations in 2012.

Customer Research Publications

Continuing customer success in publishing using dense array EEG is evident with over 45 publications in the first quarter of 2011. These publications cover a wide range of advances in neuroscience and medicine, including research on autism spectrum disorder, traumatic brain injury, speech processing, language, sleep, depression, anxiety, stress, memory, and brain computer interface.
