Interesting rate for clinical purposes are today below 60 amp/s - and forresearch purposes
up to 128 samp/s ( in acquisition theory sampling rate must be bigger thandouble of freq of interest , but in practice should be at least 3 or 4 times more ) .
I think 256 samp/rate is a good rate - maybe we should reserve some bandwidth for future additional
channels ( for more electrodes or other feedback sensors) -
eg. a "weird interfeedback" where the one's data
control stimuli of other's ( in a harmonizing session maybe through Internet , where the feedback
practitioner stays on one side and the user/patient stays on the other ) allowing reach more people .
( or, from the incoming patient data , OpenEEG database could select the best therapist possible for
that kind of sample , or goal desired )

Don't you think the sampling rate 256Hz (3.9ms) is too low????
40 Hz is sampled only 6.4 time/cycle
20 Hz is sampled 12.8 times/cycle
If we use 1024 Hz (0.976ms) sampling rate
40 Hz will be sampled 25.6 times/cycle
Is there any technical difficulty using 1024Hz sampling??
