[Eeglablist] EEG example data

[Jan Brogger]

Regarding the recent post on EEG samples from anesthesia. Is there an
interest in providing samples of clinical EEG data? We're a clinical
neurophysiology department with >2000 EEGs yearly, from a wide variety of
pathology including anesthesia/intensive care and epilepsy video long-term
monitoring. All outpatient and inpatient EEGs are described in a structured
database (EEG activity start/stop time and event classification) , so we
could extract EEGs including various types of spike activity, dysrhytmias,
demographic groups, clinical diagnoses and intensive care/SAH/postanoxic
injuries. There are now 20,000 EEGs in this database. We could also extract
just specific EEG segments with various pathologies.

The database is described in:
Aurlien H et al. Clin Neurophysiol. 1999 May;110(5):986-95 "A new way of
building a database of EEG findings."
Aurlien H et al. Clin Neurophysiol. 2004 Mar;115(3):665-73. "EEG background
activity described by a large computerized database." 

Would there be an interest in providing anonymized samples of EEGs from this
database? This would require ethical committee approval. But if there is a
substantial interest from the community, we may be able to do this. We have
a longer-term ambition to move into quantitative EEG, so please indicate if
you have any concrete projects as well. We just started using EEGLAB.
