Research paper using EMSE mentioned on NPR
4.15.04 EMSE software has been used in a paper described on NPR's "Morning Edition". The paper, entitled "Neural Activity When People Solve Verbal Problems with Insight" by Mark Jung-Beeman et al., is published by the Public Library of Science. It investigates the neurological basis of the "Aha!" moment commonly encountered during problem solving when a solution appears suddenly, and seemingly without conscious intervention. The authors point out that this type of process also occurs in many other cognitive tasks such as memory, language comprehension and creativity. The researchers used EMSE 5.0 to remove ocular artifacts and to perform time-frequency (wavelet) analysis on the EEG data, as well as localizing EEG/ERP signals using a realistic head model derived from MRI data. You can listen to the story on NPR's website.

Dr. Richard Greenblatt brought a poster describing a new method for estimating electrical sources from wavelet-transformed data. Wavelet (time-frequency) analysis is a new feature of EMSE 5.0. Senior scientist Mark Pflieger also presented a poster detailing the use of predictive information to extract meaningful relationships between time series that are nonlinearly coupled, without making any prior assumptions about the underlying dynamics.

EMSE Workshop at IRCS, Univ. of Pennsylvania
04.05.03 We had a successful workshop at the Institute for Research in Cognitive Science; 25 participants brought their laptops for a unique hands-on demonstration/laboratory. Topics included multimodal (EEG/MRI) source estimation and dynamic imaging, time-frequency analysis using the wavelet transform, and 2D/3D tiling and boundary element models, and many other features of EMSE Suite  version 5.0, such as statistical nonparametric mapping. Our thanks to John Kounios for hosting the meeting, all the participants for their valuble feedback, and everyone else who helped make it happen. If you missed it, we hope to see you at the next one!
