Re: How to detect "Readiness Potential"

Hi Chuck, 
 
thank you very much for your reply. Yes, the procedure you explained should work but - I guess - only because the subject only makes a move. Morever, since the subject knows he is going to move, the development of the movement is slower then the "readiness potential" is amplified. There are several papers  about it. 
 
We actually would like to establish it in a "real" situation in which the subject has full movement and is not required to make any movement.
 
at the moment, we are trying with a spectral analysis just before the move. Have you any material (even in matlab) such as the "readiness potential" that you extracted, or something similar that you could pass to me?
 
Thanks again for your availability, 
 
 
Valerio
