Tracking bilingual brain processing at high spatiotemporal resolution reveals where and when second language slows down

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

Neural ensembles for music production recruit more language instruments as rhythmic complexity increases

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.

Phasor diagrams clock oscillatory hemodynamic switching between overt speech production and micro resting states

This study uses rapid phase-encoded fMRI and phasor diagrams to show dynamic switching between the default mode network and language network during speech production and micro resting states.

Hemodynamic traveling waves transport musical codes faster than language codes via shared bilateral streams

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.

Phase-encoded fMRI tracks down brainstorms of natural language processing with sub-second precision

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.

Word structure tunes electrophysiological and hemodynamic responses in the frontal cortex

This study investigates how word structure affects brain activity in Chinese speakers using EEG and fNIRS, finding distinct patterns for morphological priming and word structure effects.
