Hi all,

I am currently working on retinotopy data and I managed to get the maps but I don’t really understand the angle meanings in the polar case. Like is zero angle meaning horizontal or vertical stimulus.

The reason it is puzzling me is that I seem to get response over the whole 360 degrees from both hemispheres so I am thinking there is probably some error in the scale.

We use a double rotating wedge as our stimulus.

I would appreciate if some one would assist by giving an explanation of the output of the retinotopy analysis in FS.

Thank you,

Mohamed
