Cortical Functional Neuroimaging With SPM and FreeSurfer
While SPM and FreeSurfer are among the most popular programs used for the analysis of functional and structural brain imaging data, their integration in the context of modeling cortical task-related and intrinsic activity can pose significant procedural challenges. Cortical Functional Neuroimaging With SPM and FreeSurfer is an intermediate-level, 5-day workshop that will provide you with the essential skills required to use SPM and Freesurfer together for modeling fMRI data in native, MNI or cortical surface anatomical spaces It is designed for investigators having familiarity with the fundamental principles of fMRI measurement and design, with at least six months experience in functional neuroimaging data acquisition and analysis.
This strongly interactive workshop will focus on the use of SPM8, FreeSurfer and their extensions for preprocessing, statistical modeling, visualization and anatomical labeling. Demonstrative examples will be drawn from a wide range of the instructors' experimental work covering a range of basic and clinical fMRI experimental designs. Extensive coverage will be given to structural and functional MRI quality assurance methods to facilitate artifact detection and mitigation at various analysis stages.
A unique feature of the course will be thorough coverage of methods for automating analysis workflows using the Nipype, a novel and powerful image processing environment of rapidly increasing popularity.
As the presentations will include in-class demonstrations and homework assignments, participants are expected to bring a laptop with MATLAB, SPM8, FreeSurfer and MRIcron already installed. Detailed setup instructions can be found here.
Because of the highly interactive nature of this workshop, enrollment will be limited, so register now to reserve your spot.
