Re: using triggers to start/stop the display (not the saving)

Re: using triggers to start/stop the display (not the saving)

Best wishes
Lena

Hi Anyone who can help, We are experiencing a weird event where ALL our triggers are showing up perfectly fine on the ActiView interface. However, when then loading the saved bdf file in any way we can think of, several triggers are missing. There are generally between 100 and 400ms between these tr...

Re: Biosemi for recording motor-evoked potentials

Hi, I would like to follow up on the suggested issue of ' electrode polarization' and the TMS threads mentioned. I am not entirely sure I understand what 'electrode polarization' is, how it comes to be or can be avoided (if at all possible). The only explanation I can find in the TMS threads relates...
