New LTM Recommendations
EGI announces new guidelines for Long-Term Monitoring (LTM) recordings with our Geodesic EEG System 300 (GES 300) and HydroCel Geodesic Sensor Net 120 LTM (HCGSN 120 LTM).
Upon the completion of systematic skin safety testing with our 256-channel adult (small, medium, and large) and pediatric large sizes, we are increasing our maximum recording time to 24 hours with a single net application.
Additional testing is underway for our Nets of other channel counts (128, 64, and 32) and sizes. Until that testing is complete and EGI release new guidelines for these nets, they remain covered by the 12 hour maximum recording duration.
Multiday recordings are feasible by removing and reapplying the Nets following EGI's standard procedures for LTM recordings. A new quick reference placard will soon be available to customers. As with all electrodes applied to the skin, each patient should be evaluated periodically during recording to verify that excessive skin irritation is not occurring. This is particularly true with young patients whose skin is not fully mature. The guide includes a maintenance schedule for long-term recordings and procedures for assessing skin condition and data quality.
The new HCGSN 120 LTM session maintenance placard joins EGI's series of placards, which are designed to improve clinical workflow. For a list of available Net placards for clinical customers, see below. These materials represent one of the many layers of EGI customer support. In addition to EGI’s standard support, which includes phone and email support, installation and training visits, full system documentation, and more, EGI also offers educational events, podcasts, white papers, training videos, and more.

Learning in Sleep / Lernen im Schlaf
Does sleep play an active role in consolidating what we learn during the day? Do the nerve cells need to relax during sleep in order to absorb new information? Watch the video on Prof. Reto Huber's work on sleep and learning at the Kinderhopital in Zurich. You can also download the pdf of the English translation of this video. To learn more about the work of Dr. Huber's group at the University Children's Hospital in Zurich go to www.kispi.uzh.ch/sleep.
Hat der Schlaf eine aktive Funktion und festigt das, was wir tagsüber aufnehmen? Oder erholen sich die Nervenzellen im Schlaf, um wieder neue Informationen aufnehmen zu können? Im Zentrum für Schlafmedizin des Kinderspitals Zürich werden Kinder und Jugendliche mit Elektroden verkabelt und absolvieren vor dem Zubettgehen spezielle Lerntests.

EGI's First Customer Receives the US National Medal of Science
Dr. Michael I. Posner of the University of Oregon named as one of nine eminent researchers to receive national award.
EGI's first customer was Dr. Posner, who in the early 1990's recognized the value of dense array EEG for psychological research. Dr. Posner is currently Professor Emeritus at the University of Oregon and Adjunct Professor at the Weill Medical College in New York in the Sackler Institute. His current work deals with the development of brain networks underlying attention and self regulation. Dr. Posner has long been regarded as an authority in the field with over 500 articles and citations on his work on understanding attention and self regulation.
Dr. Posner has been invited to the White House on October 7, where President Obama will award him with the National Medal of Science. Dr. Don M. Tucker, CEO and CSO of EGI, said "Many of us have long been aware of Mike's importance not only to dEEG studies but to cognitive neuroscience generally. It is gratifying to see this recognition at the highest national level."

The Brain as the Ultimate Computer Interface
EGI’s Geodesic Sensor Net (GSN) is prominently featured in a riveting story on brain-computer interfaces (BCIs) in the November issue of Scientific American. Once restricted to the imagination of science fiction writers, commercial BCI technologies are now emerging from several lines of research. EGI’s recent release of Amp Server Pro for real-time EEG streaming is now supported by BCI2000, making it clearer than ever that EGI’s dense-array technology will continue to play a pivotal role in shaping this fascinating technology.
Mapping Sexual Desire with Dense-Array EEG
The November cover of NeuroImage highlights the research of EGI customer Dr. Stephanie Ortigue of UC Santa Barbara. In this novel study, Dr. Ortigue and colleague Dr. Francesco Bianchi-Demicheli used dense-array EEG to track the spatio-temporal dynamics of sexual desire using visual evoked potentials and a behavioral desire decision task. Using the LAURA distributed linear inverse, the scientists found recruitment of the superior temporal sulcus (STS) and temporoparietal junction (TPJ) within 200 ms of viewing desired images. Because the STS and TPJ are known to be involved in social cognition, attention, integration of body-related information, and self-processing, Ortigue asserts that those functions must play a crucial role in the coding of sexual desire.

On a Mindbender
Talk about a noisy environment! EGI's acquisition system successfully collected EEG data from individuals riding Mindbender, the world's largest indoor high-speed, triple-loop roller coaster. The EEG work was part of a study to collect and compare the brainwaves of thrill-seeking and thrill-adverse individuals as they rode the giant roller coaster housed in Canada's West Edmonton Mall.
Mindbender, and the EEG work, was featured in "SuperCoasters," a TV special that aired on the National Geographic Channel. More details and a video are available at http://channel.nationalgeographic.com/episode/supercoasters-2619/Overview and http://news.nationalgeographic.com/news/2006/05/060524-coasters_2.html.
GSN in Wall Street Journal and on PBS
An article in the March 24, 2006, issue of the Wall Street Journal profiled a PBS program called "The New Medicine." Accompanying the article was a photo of Buddhist monk Barry Kerzin wearing a GSN. According to "The New Medicine" website, Kerzin participated in a study to examine how meditation can help us train our minds to make us more resilient.
"The New Medicine" profiles other alternative approaches and explores the shift in health care toward a more holistic approach that treats the whole person, not just the disease. The website says that patients and doctors alike are promoting this integrative approach, which encourages patients to become active participants in the care of their own health.
Measuring Tissue Conductivity
In collaboration with the University of Oregon Neuroinformatics Center, EGI scientists are developing methods for measuring the conductivity of the tissue of the human head. Accurate skull conductivity is particularly important in evaluating data from infants and children.
The initial report on implementing this conductivity scanning approach with high-performance computing won the "Best Paper" award at the 2005 International Conference in Computational Science. A summary of this report was recently published in Advances in Clinical Neuroscience and Rehabilitation.
Dense-Array EEG in Lie Detection
The February 6, 2006, issue of the New York Times magazine explored the art and science of lie detection, a topic of current interest to federal agencies concerned with "credibility assessment."
Featured on the magazine cover is EGI's Geodesic Sensor Net, which researchers at the University of South Carolina are using to study deception. The article discusses other tools such as functional magnetic resonance imaging machines, thermal scanners, eye trackers, the old-fashioned polygraph, and the even-older practice of face reading (receiving a twenty-first-century updating by the Facial Action Coding system, a precise categorization of 10,000 or so facial expressions).
