Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Functional magnetic resonance imaging (fMRI) is a non-invasive test used to detect changes in brain activity by taking picture of changes in blood flow. The imaging helps doctors better understand how the brain works. Task based fMRI (TB fMRI) prompts patients to perform different activities (e.g. word selection in a reading task), and is routinely performed on patients in preparation for a Neurological surgery (surgery that involves the nervous system, brain and/or spinal cord). The purpose is to locate areas of the brain that control speech and movement; these images will help make decisions about patient surgeries. However, there are however gaps in knowledge specific to the language areas of the brain, especially for non-English patients and bilingual patients (those who are fluent in more than one language). This study proposes to evaluate if resting state fMRI (RS fMRI) that does not require any tasks, along with a novel way to analyze these images using "graphy theory," may provide more information. Graph theory is a new mathematical method to analyze the fMRI data. The overall goal is to determine if graph theory analysis on RS fMRI may reduce differences in health care treatment and outcomes for non-English speaking and bilingual patients. We hope that the results of this study will allow doctors to perform pre-operative fMRI in patients who do not speak English.

Bilingual Participants with Glioma

Bilingual (English and Spanish speaking) patients will be recruited from the clinical service of the Department of Neurosurgery of MSK. All patients on the Neurosurgery service scheduled to undergo a resection of a tumor in or adjacent to the primary language areas will be screened to participate in this study.

The study will be performed in concert with patient's regularly scheduled clinical care for his/her brain tumor. Clinical care (which will be performed whether or not the patient participates in the current study) will include: 1) pre-operative routine (anatomical) MRI and fMRI, 2) the surgery to remove the tumor, 3) intra-operative cortical stimulation to identify the essential motor and/or language areas. It should be stressed that neither the brain tumor surgery, nor the intra-operative cortical mapping will be changed in any way from routine practice.

Multilingual Aphasia Examination

Intervention Type BEHAVIORAL

For patients only prior to MRI scans.

The MAE contains eleven subtests in five categories which may be used to assess both languages in bilinguals and the participant's primary language in monolinguals: Oral Expression, Spelling, Oral Verbal Understanding, Reading, and Rating Scales. Subtests are scored for accuracy of individual items on a three-point scoring system (0, 1, 2). Contained within these domains are The Token Test, Aural Comprehension of Words and Phrases and Visual Naming which naturally parallel fMRI and direct cortical stimulation behavioral assays already in place for clinical use (phonemic fluency, auditory responsive naming and confrontation naming respectively). The MAE is expected to take under 50 minutes.

Language paradigms + RS fMRI

Intervention Type DIAGNOSTIC_TEST

10 monolingual patients: 2 language paradigms + RS fMRI = 7x3 = 21 minutes 10 early bilingual patients: 2 language paradigms+ RS fMRI = 7x3 = 21 minutes 10 late bilingual patients: 2 language paradigms+ RS fMRI = 7x3 = 21 minutes

Healthy Volunteers

Normal, healthy volunteers who express interest in participation and who meet the eligibility criteria will be recruited for this study. It is anticipated that healthy volunteers will mostly consist of medical professionals. They will consist of 10 monolinguals (defined as native English speakers), 10 early bilinguals (defined as acquiring proficiency in the second language before 10 years of age), and 10 late bilinguals (defined as acquiring proficiency in the second language after 10 years of age).

Language paradigms + RS fMRI + one anatomical sequence

Intervention Type DIAGNOSTIC_TEST

10 monolingual English volunteers: 2 task language paradigms\* + 1 Resting State fMRI + one anatomical sequence for a total of approximately 25 minutes.

10 late bilingual volunteers: 4 language paradigms (2 English + 2 Spanish) + 1 Resting State fMRI + one anatomical sequence for a total of approximately 39 minutes.

10 early bilingual volunteers: 4 language paradigms (2 English + 2 Spanish) + 1 Resting State fMRI + one anatomical sequence for a total of approximately 39 minutes.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

All patients and volunteers will be recruited by listed consenting professionals. Volunteers do not need to be MSK employees.

* Patients/ healthy volunteers ≥ 18 years old
* Patients/ healthy volunteers must be able to perform the language paradigms on cue while inside the scanner
* Patients/ healthy volunteers who are monolingual English speakers, early bilinguals (English and Spanish) or late bilinguals (English and Spanish)
* Patients must be newly diagnosed with a glioma (from prior histology) or must be suspected to have a glioma on imaging (to be confirmed by post-operative histology)
* Patient's location of the tumor must involve the expected location of Broca's area (left pars opercularis and/or pars triangularis). This determination will be made on the basis of a pre-operative MRI by a fellowship-trained Neuroradiologist
