Dynamic acoustic-to-categorical representations of phonemes and prosody along ventral and dorsal speech streams

This repository contains data and code accompaning: Baek, S-C., Kim, S-G., Maess, B., Grigutsch, M., & Sammler, D. (2026). Dynamic acoustic-to-categorical representations of phonemes and prosody along ventral and dorsal speech streams. Nature Communications, 17, 6082. https://doi.org/10.1038/s41467-026-75240-0 This study investigates cortical representational dynamics of phonemes and prosody using time-resolved representational similarity (RSA) and multivariate transfer entropy (mTE) analyses applied to MEG and behavioral psychophysical data. In this repository, we provide the auditory stimuli and individual behavioral responses collected during the MEG experiment, as well as the processed neural data including the neural representational dissimilarity matrices (RDMs) and time-resolved RSA and mTE results based on the regions of interest (ROIs). The scripts provided here are to replicate the ROI-based RSA and mTE analyses, as well as the main figures (Figs 1-6.).
