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.
Upcoming

powerful set of features. Topics included the wavelet transform,
spatial components analysis (PCA & ICA), tissue segmentation with hidden
Markov random fields, 2D and 3D tiling, and source estimation in the time,
frequency and time/frequency domains. Our thanks to Dr. Pangiotides and

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
