FMRI - Data analysis
3 important questions on FMRI - Data analysis
Why is analyzing fMRI data difficult?
- Large quantity of data
- weak signal of interest
- complex temporal + spatial noise structure
What are popular techniques in fMRI ?
- Signal (process) - Signal (baseline)
- BUT, this assumes pure additivity between processes = oversimplified assumption
Factorial (ANOVA) designs
- dissociations or interactions
Parametric modulation
- correlation of fMRI signal with additional measurements
What are the three steps fro general analysis of fMRI?
- Design specification (building/specifying the model appropriate for data)
- Estimation (frist reel analysis = subject specific)
- Group analysis ( second level anywise = group specific)
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
