In module 2, we explored the principles and applications of fMRI, including task-based and resting-state imaging. We learned how fMRI detects brain activity through BOLD signals, with clinical uses in diagnosing stroke, epilepsy, and psychiatric disorders. Real-world case studies demonstrate its role in recovery and surgical planning.

Principles of fMRI
Functional MRI (fMRI) measures brain activity by detecting changes in levels.
The delay of the hemodynamic response to peak after a stimulus is approximately seconds.
Techniques for Measuring Brain Activity
In resting-state fMRI, brain activity is measured when the participant is .
Using task-based fMRI, researchers can identify specific brain regions involved in functions such as and motor skills.
Clinical Applications of fMRI
fMRI has clinical applications in diagnosing by pinpointing the location of seizure foci for surgical intervention.
Altered connectivity in the Default Mode Network (DMN) is often associated with .
