Variability in the analysis of a single neuroimaging dataset by many teams

Rotem Botvinik-Nezer, +220 more
- 04 Jun 2020 - 
TL;DR: The results obtained by seventy different teams analysing the same functional magnetic resonance imaging dataset show substantial variation, highlighting the influence of analytical choices and the importance of sharing workflows publicly and performing multiple analyses.
Journal ArticleDOI

Audio-visual integration of emotion expression.

TL;DR: Results of three experiments on multisensory perception of emotions using newly validated sets of dynamic visual and non-linguistic vocal clips of affect expressions indicate that the perception of emotion expressions is a robust multisENSory situation which follows rules that have been previously observed in other perceptual domains.
Journal ArticleDOI

Functional specialization for auditory–spatial processing in the occipital cortex of congenitally blind humans

TL;DR: It is concluded that some regions of the right dorsal occipital stream do not require visual experience to develop a specialization for the processing of spatial information and to be functionally integrated in a preexisting brain network dedicated to this ability.

Variability in the analysis of a single neuroimaging dataset by many teams (Preprint)

Rotem Botvinik-Nezer, +196 more
TL;DR: In this paper, the same dataset was independently analyzed by 70 teams, testing nine ex-ante hypotheses, and the results showed that analytic flexibility can have substantial effects on scientific conclusions, and demonstrate factors related to variability in fMRI.
Journal ArticleDOI

Cross-modal plasticity for the spatial processing of sounds in visually deprived subjects.

TL;DR: Recent results regarding the spatial processing of sounds in blind subjects are described to suggest that blind individuals may demonstrate exceptional abilities in auditory spatial processing and that such enhanced performances may be intrinsically linked to the recruitment of occipital areas deprived of their normal visual inputs.
