Thanks a lot Elam and Keith. Then, can I ask you one more question?
Can I know about the stimulus size of the working memory task paradigm? I also want to know about the visual angle for this task paradigm. There was no information about it in the manual or any papers. Sincerely, Bo-yong Park. ᐧ 2016-12-24 3:15 GMT+09:00 Keith Jamison <[email protected]>: > The files that Jenn pointed to are the stimulus MASKS, which of course is > the most important aspect of the retinotopy stimulus, but it is worth > noting that the stimulus itself is not a standard checkerboard, but a > rapidly changing collage of real-world objects, faces, etc. You can find > more information about the stimulus here: http://kendrickkay.net/ > analyzePRF/ > > -Keith > > On Fri, Dec 23, 2016 at 12:50 PM, Elam, Jennifer <[email protected]> wrote: > >> Hi Bo Yong, >> >> Attached is the 7T Retinotopy protocol off the scanner and here is a >> summary of scan parameters: >> >> >> >> The stimulus size/diameter was 16.0 deg for HCP 7T, which is especially >> important for the retinotopy data.
