Background

The question of how language and music are represented in the human brain is one of the more challenging problems of contemporary cognitive neuroscience and neurolinguistics. During the past two decades, advances in neuroimaging technology have produced a greater understanding of higher cognition, including language and music. 

This project is unique in bringing together behavioral and neuroimaging research on language and music in both healthy subjects and patients with dementia. With recent studies showing that dementia affects approximately one in ten adults ages 65 and older in the United States – and over 55 million people worldwide – it is increasingly important to understand how language and music correlate with reduced prevalence of this condition.

Project Description

Building on the work of previous teams, this project team will use a combination of neuroimaging and behavioral data to establish language and music mappings in professional musicians who are either monolingual or highly proficient bi-/multilingual; and examine the effect of musical training and bi-/multilingualism on dementia and cognitive impairment.

This team’s experimental design includes data collection from human subjects through the use of neuroimaging, such as fMRI, DTI, rsfMRI, EEG, as well as behavioral data, such as interviews, recordings and language proficiency testing. The imaging protocol is designed to elucidate how languages and musicianship are processed in the human brain, including potential interactions in sensory-motor networks. The behavioral data collected from musicians will establish a relationship between extensive musical training and its possible advantageous effects on dementia symptoms.

Anticipated Outputs

Imaging and behavioral data; conference presentations; manuscripts for publication

Student Opportunities

Ideally, this project team will include 2 graduate students and 10 undergraduate students from disciplines such as neuroscience, linguistics, music and medicine. 

Students will have the opportunity to work across all research protocols, including behavioral data collection on multilingualism and musicianship; active learning of EEG technologies, data collection and analysis using NeuroGuide software; and comparisons of results from healthy subjects and patients. Students are expected to participate in both data collection and analysis, as well as in efforts leading to publications and grant applications. They may also have the opportunity to gain presentation experience at conferences. 

During full team meetings, students will participate in a journal club and discuss related academic literature as well as any obstacles they are facing in their research. Team members will be empowered to take ownership over specific aspects of each project.

Timing

Fall 2024 – Spring 2025

• Fall 2024: Add new students to Institutional Review Board (IRB) protocol; conduct fMRI, DTI, rsfMRI, EEG and behavioral data collection; begin data analysis
• Spring 2025: Continue data collection and analysis; prepare manuscript for publication
