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.
Running Freesurfer v5.3.0
Thank you
Walid
