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 ?

Cognitive subtraction
  • 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?

  1. Design specification (building/specifying the model appropriate for data)
  2. Estimation (frist reel analysis = subject specific)
  3. 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
Remember faster, study better. Scientifically proven.
