  1. # Distinct perceptual and conceptual representations of natural actions along the lateral and dorsal visual streams: an EEG-fMRI fusion study
  3. October 2025
  5. This project contains preprocessed EEG data and fMRI and EEG RDMs. During EEG and fMRI recordings, participants viewed 95 videos depicting everyday actions. Representational dissimilarity matrices (RDMs) were extracted using a searchlight approach (fMRI) and time-resolved approach (EEG). Feature RDMs used in representational similarity analysis are included in the datasets (`models.mat`). See https://www.biorxiv.org/content/10.1101/2025.09.17.676633v1 for details. Associated code is available on GitHub.

Code availability statement

The paper has a code availability statement. Its license (CC BY-NC-ND) does not allow reproducing it here; in short, from what the harvester recognized in it:

Read it in the paper: doi.org/10.1038/s42003-026-09834-1.

Tracing map

Proposed by the machine: these links were found in the paper and verified at the source, without human review. The map will receive a Zenodo DOI once one of the paper's authors has validated it with their ORCID.

What the map holds:

  • 1 repository of the authors' code, each at its verified commit, with its license and how the link was found in the paper;
  • 0 scripts, each with its path and the digest of its content;
  • no match between paragraphs and code yet;
  • neither the text of the paper nor the code itself.

Its JSON (tracing-map.json) is deposited on Zenodo with its DOI once the map is validated.

Data

No dataset and no data link were found in the paper.

Data availability statement
