This repository contains the code and data for the paper titled; "Hierarchical microstructural tissue growth of the white and gray matter of human visual cortex during the first year of life (2025)" Authors: Karla Perez, Ahmad Allen, Christina Tyagi, Sarah S.

This project examines the development of microstructural tissue properties in gray and white matter of three visual processing streams - the dorsal, lateral, and ventral streams - during the first year of human life.
The repository is organized as follows:
code/: Contains analysis scripts for each figure in the paper (MATLAB scripts for all figures)
data/: Contains the necessary data files (in .mat format) to run each analysis
Tool Requirements
- MATLAB (Code was written and tested using MATLAB R2020b, and it should be compatible with both older and more recent MATLAB versions).
- For infant brain surface reconstruction and analysis, we used a specialized version of FreeSurfer: freesurfer-linux-centos7_x86_64-infant-dev-4a14499-20210109. This is a developmental version of FreeSurfer specifically optimized for infant brains. More information about infant Freesurfer can be found at: https://surfer.nmr.mgh.harvard.edu/fswiki/infantFS
