Brain Differences in Monolingual and Highly Proficient Multilingual Speakers

# README

## About the data/participants:
# Data:
The set of data includes T1 weighted images from 30 participant adults. Data was collected at a 3T Skyra scanner, in 2020
# participants:
15 of these participants (subject numbers sub-01 - sub-15 ) are monolinguals English speakers,
the next 15 (sub-16 - sub-30) are multilinguals, they all speak Romanian as a native language,
Russian as an early L2, English as a late L3,
and all know at least two or more additional languages (i.e., see Midrigan-Cichina et al., 2023 and Midrigan-Ciochina et al., 2024, for a table with additional background information)

## Overview

#Project Name:
Multilignuals Study
The project ran 1 year, we have collected functional data ( for a linguistic task in which participants were listening to sentences in English, Russian, and Romanian).
We have also collected resting state MRI ( the data included in this set is only T1 and DWI; we are still working on the other manuscripts).
# Project Goal:
The project's objective was to understand the brain restructuring patterns and functional differences, that are associated with high proficiency in multiple languages.
# Methods:
MRI data acquisition:
The participants were scanned with a Siemens 64-channel 3-Tesla "Skyra" MRI System, (Siemens Healthcare, Erlangen, Germany) at the Imaging Research Center of the University of California, Davis.
For the structural data, a T1-weighted imaging sequence was used, with an MR-RAGE (TfL) sequence with a voxel size = 0.9x0.9x0.9 mm3, FOV = 243 × 243 mm, 208 sagittal slices, 7-degree flip angle, TR = 2500msec, TI = 1100 msec, and TE = 4.44 msec, Bandwith 160 Hz/Px; GRAPPA = 2, 32 reference lines.
