Aims and MethodsAims-Learn to implement block and event-related fMRI experimental designs
-Learn fMRI data pre-processing steps
-Learn fMRI data post-processing: GLM and group analysis
1) We learned the details of fMRI pre-processing steps. This course allowed for discussion and understanding of slice-time correction, motion correction, spatial smoothing
2) We learned the details of post-processing including the use of the GLM for modeling our fMRI experiment. We also learned the analysis of individual and group level data.
3) AFNI- A good tool for understanding the complicated steps of analysis.
4) There is no recipe for fMRI analysis. Each study design and each analysis is unique which requires detailed understanding of the processing steps.

How much movement is too much?
Depends on many things:
-the type of movement (sharp movement vs. drift)
-timing of the movement (during a trial vs. during a break period)
-the resolution of your data:
3 mm movement may be okay if you are collecting 3.2 X 3.2 X 3.2 mm3 resolution but may not if you are collecting 1.0 X 1.0 X 1.0 mm3
No specific criteria, the investigator must decide!!
