Marburg Co-speech Gesture IFG fMRI
The Role of the Left and Right Inferior Frontal Gyrus in Processing Metaphoric and Unrelated Co-speech Gestures
Task fMRI of adults judging whether speech and co-speech gestures in short videos match, collected to compare inferior frontal gyrus activation and laterality for metaphoric, iconic and unrelated gestures. Raw images are not shared; per-subject contrast maps are public.
Overview
This entry covers the functional MRI cohort of a 2021 NeuroImage study by Steines, Nagels, Kircher and Straube at the Department of Psychiatry and Psychotherapy of Philipps-Universität Marburg. The study asked how the left and right inferior frontal gyrus (IFG) respond to different kinds of co-speech gestures. It found that abstract speech with metaphoric gestures and concrete speech with unrelated gestures both raised bilateral IFG activation compared with concrete speech paired with fitting iconic gestures, with a leftward bias for the metaphoric condition and a rightward bias for the unrelated one. The raw scans are not released. The authors posted derived maps, masks, scripts and behavioral tables on OSF.
Composition
74 subjects took part. The paper abstract does not give sex, age or clinical status, so none of these are listed here. The OSF deposit has one first-level folder per subject, numbered sub-01 to sub-74.
Acquisition
During scanning, subjects watched 5 second video clips and judged whether the content of the speech and the gesture matched. The design has conditions for abstract speech with related metaphoric gestures, concrete speech with related iconic gestures and concrete speech with unrelated gestures; the OSF data also include an abstract speech with unrelated gesture condition that the paper does not analyse. Preprocessing in SPM12 covered realignment, normalization and smoothing. Scanner, field strength and sequence parameters could not be confirmed from an openly reachable source and are left out.
Annotations
The OSF project provides, per subject, SPM contrast and t maps for each of the four conditions, plus group-level flexible factorial results, eigenvariates from three IFG volumes of interest, left, right and bilateral IFG masks built from AAL regions, hit and false alarm rates, and item scores on the BAG gesture scale.
Known limitations
- Only derived statistical maps are public; raw and preprocessed functional images are not shared.
- No license or data use terms are stated for the OSF files.
- Demographics and scanner details are missing from this entry because the full paper text could not be opened.

The data are not available outside the institution or study that holds them
The OSF project holds only derived data: SPM12 first-level contrast and t maps for each of the 74 subjects, second-level group maps, eigenvariate files, anatomical IFG masks, analysis scripts and behavioral tables. Raw or preprocessed functional images are not part of it and no other route to them is given.
No published license or data use terms
The data holder has published no license and no data use terms. Any use, sharing or commercial right has to be agreed with the data holder, and nothing can be assumed to be allowed. Default copyright and data protection law still apply.
The OSF project states no license, and the deposited derived maps carry no data use terms. The paper itself is published under CC BY-NC-ND, which does not cover the data.
