eeg with Arduino

Hello,

Has anyone experience with EEG modules? I see there are modules with 80$ and others with 1000$. What difference do they have? Also, which Arduino is capable of some serious EEG DSP? Where to start from? I ask for your experience,suggestions...

Thank you

Get a ads1292R, it has respiro and RR detection. Price is ~$30-50.

Thank you,

Really, can ADS1292R give 24-bit resolution?

Thank you...

oops, sorry, error: ADS1292Ris for ECG not EEG.
