Hi Marco,
right now I don;t have any ERP data, this weekend there will be a demonstration
by Deymed on the ERP software. From that moment on I will collect ERP data. I'm
willing to share it with you, PROVIDED that future clients approve of it.
I do have QEEG data, under different taskconditions (1 and 2 digit counting,
reading luod, reading silent, listening, Strrop color/word tests, Raven
pictures and some stimulation tasks as well: hyperventilation and
Photostimulation)
If you need it I will ask clients for permission. But only after I fully
checked medical -ethical matters.
Met vriendelijke groet/All the best/Ciao,

Subject: [esnr] Call for data
Hello,
I am working on a new method for studying (left/right) hemispheric
joint-involvements. The major advantage of the approach I am following, as
compared to usual interhemispheric asymmetry, coherence and phase measures, is
that the WHOLE hemispheric involvements (patterns of activation) are considered
simultaneously, and not just an electrode pair at a time.
The method is based on Matrix Decomposition methods and, possibly, extension
of Blind Source Separation (Independent Componenet Analysis).
For the study, I am looking for individual subject data, where each subject
is involved in, say, two tasks, where the two hemisphere should interact
differently. Examples are:
- Reading of words with emotional and non-emotional content
- Looking at face expressing emotions vs. neutral faces
- Analytic vs. Spatial tasks
- Maniac vs. Depressive phase of Bipolars.
etc.
Preferably, I would like to start analyzing ERP data, since they are shorther
and cleaner files.
Also because for ERP data it is possible to extend the method to study the
interaction of hemispheres with specific time-lags (e.g., study the
relationship if activity at peaks).
I cannot offer autorship to the records owner for possible methodological
papers coming out from this study.
However I will aknowledge and I will share any insight acquired with the data.
If then those insights are worth, an applied paper in co-authorship would be
more than welcome.
Thank you very much for your attention.
