At the JEONG Lab, we investigate how people learn and use multiple languages, and how the brain supports these processes. Using neuroimaging techniques such as fMRI and behavioral experiments, we explore how memory, emotion, and social interaction influence language.
We also aim to uncover, from both neurocognitive and social perspectives, the mechanisms by which individuals learn languages, communicate, and make multilingual and culturally grounded behavioral choices in diverse and international contexts.

202501.16 Neural Mechanism for Integrating Syntax and Information in Sentence Comprehension (article in press) Posted in Publication

Using fMRI to examine linguistic theories, the collaborative research led by Professor Masatoshi Koizumi from the Graduate School of Arts and Letters at Tohoku University, titled “The crucial role of the left inferior frontal gyrus (BA44) in synergizing syntactic structure and information structure during sentence comprehension,” has been published in the international journal Brain and Language.

This study investigated how the brain integrates syntactic and information structures during sentence comprehension, focusing on Japanese sentences with different word orders (SOV and OSV). The findings revealed that the left inferior frontal gyrus (BA44) plays a crucial role in coordinating these processes.

The findings highlight the dynamic interplay between linguistic structures and informational structure in the human brain, contributing to a deeper understanding of the cognitive and neural foundations of language comprehension. Additionally, the study underscores the effectiveness of fMRI as a powerful tool for elucidating the neural mechanisms underlying language processing. (Jeong)
