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.
