[Eeglablist] EEG example data

[Ernesto Pereda]

I myself would be very interested in having access to samples for this 
database, especially data of patients under anaesthesia as well as EEG 
records during sleep (especially if the hypnogram is available in this 
later case), and would be delighted to collaborate in this regard. I am 
currently involved in studying changes in the relationship between 
scalp EEG sites in these two situations both pairwise and 
collectivewise using linear and nonlinear multivariate analysis 
techniques. Comparisons between normal subjects and subjects with 
pathologies would be especially interesting. If polysomnograophies are 
also at hand (i.e., not only the EEG but also Heart Rate and 
respiration during sleep), even better. Maybe I am asking too much!. 
Thanks in advance anyway
