This study uses rapid phase-encoded fMRI to identify temporal delays in second language processing compared to first language across multiple brain networks.

This study uses continuous fMRI to analyze time-resolved hemodynamic responses during speech perception, production, and self-monitoring, identifying distinct neural components and their temporal dynamics.

This study maps neural ensembles for language and music production under varying rhythmic complexity and finds that higher complexity engages more language-related brain regions.

The paper compares the speed of information transfer between music and language using fMRI, finding musical codes travel faster than language codes through shared bilateral brain streams.

This paper develops phase-encoded fMRI techniques to track neural information flows during language processing with sub-second precision, revealing brain activity patterns as traveling waves.
