# Data for "Modeling 2D Spatio-Tactile Population Receptive Fields of the Fingertip in Human Primary Somatosensory Cortex" Susanne Stoll, Falk Luesebrink, D. Samuel Schwarzkopf, Hendrik Mattern, Peng Liu, Johanna Noelle, and Esther Kuehn --- This repository contains - data as reported in our manuscript, which is available as a [preprint](https://doi.org/10.1101/2025.05.24.655840) and [journal article](https://doi.org/10.1162/IMAG.a.1210). - data not presented in our manuscript but related to it, such as fMRI data that were not smoothed or goodness-of-fit values that were statistically adjusted for model complexity and not via a cross-validation procedure. Please report any issues by sending an email to stollsus@gmail.com. Thank you!
