I am working in the field of population receptive fields (pRF) [Dumoulin, S. O., & Wandell, B. A. (2008)]. I want to analyse an open source data for the V1 region only. I know that HCP dataset [Benson, Noah C., et al.] but I cannot really extract V1 region from it.
Furthermore, I need the data obtained with wedge/ring visual stimulus.
