Hi,
Apologies - not a direct SPM question but I am hoping a subscriber will have the information I need.
My aim is to combine tDCS with FMRI and I am trying to determine how long tDCS effects persist? Assuming a protocol of 2 amps anodal stimulation for 20 mins (and then transfer the subject to the scanner ~10 mins. Our tDCS system is not MR compatible). How long can I then scan for and be reasonably confident of picking tDCS effects?
Many thanks
