Episode notes
Serendipitous Start in Neuroimaging
- Michael Fox accidentally started in brain imaging by knocking on the door of Mark Raichle to discuss a poster on the default mode network.
- This fortuitous encounter sparked his deep interest and career in neuroimaging research.
Power of Global Signal Regression
- Global signal regression dramatically enhances anatomical specificity in resting-state fMRI.
- This step transforms noisy data into clearer functional networks, validating resting-state signals as meaningful.
Choose Global Signal Regression Wisely
- Whether or not to apply global signal regression depends on the research question.
- Removing global signal can eliminate arousal-related signals but enhance underlying anatomical specificity.
