Hi Doug, Is it possible to run retinotopy-like analysis to reveal areas in the brain responsible for a certain phase of a presented stimuli? Say, instead of presenting 0 - 360 degrees of rotating wedge per cycle, we would like to present arbitrary scale of 0 - 100 of a particular stimulus feature, that does not necessarily differ in their retinotopic locations.
We thought, if we pretend that scale-0 is equivalent to a wedge of 0 degree, and scale-50 is equivalent to a wedge of 180 degrees, and so on, we would be able to map the cortical area corresponding to each value of the scale. However, the retinotopy protocol of freesurfer requires the input of a stimulus type “e.g. polar or eccen” and direction “e.g. pos or neg”, so our analysis won’t work as we intend.
