Introduction

An important tool in functional brain mapping, FreeSurfer facilitates the visualization of the functional regions of the highly-folded cerebral cortex. It contains both volume based and surface based analysis, primarily using the white matter surface ^[1]. It has been suggested that this article or section be merged into Neuroimaging. ... Location of the cerebral cortex Slice of the cerebral cortex, ca. ...

Download

FreeSurfer runs on Mac OS and Linux. Registration and installation are easy. Related documentation can be found on the FreeSurfer Wiki ^[2].

Usage

The project's central process stream is called recon-all ^[3], which organizes raw MRI images into formats easily usable for morphometric and functional MRI statistical analysis with the FsFast package. It uses a morphed spherical method to average across subjects. Tkmedit and Tksurfer are the editing and visualization tools included in the package, but they will be replaced by Scuba when it is completed. The project also automatically segments the volume and parcellates the surface into standardized regions of interest (ROIs) that the Center for Morphometric Analysis has developed. This article or section does not cite its references or sources. ... Functional Magnetic Resonance Imaging (or fMRI) describes the use of MRI to measure hemodynamic signals related to neural activity in the brain or spinal cord of humans or other animals. ...

Interoperation

FreeSurfer is compatible with the FMRIB Software Library (FSL), which is a comprehensive library for image analysis, written by the Functional MRI of the Brain (FMRIB) group at Oxford, UK. The functional activation results obtained using FSL tools can be overlayed onto inflated, sphered or flattened cortical surfaces using FreeSurfer. Example FSL GUIs The FMRIB Software Library (FSL) is a software library containing image analysis and statistical tools for functional, structural and diffusion MRI brain imaging data. ...
