Final answer:
Functional magnetic resonance imaging (fMRI) is a brain imaging technique that examines the brain's structure and function and their relationship to personality.
Step-by-step explanation:
Functional magnetic resonance imaging (fMRI) utilizes brain imaging techniques to examine the brain's structure and function and how they relate to personality. By measuring brain activity while performing tasks, fMRI generates a map of the most active areas in three dimensions, showing changes in tissue over time. It provides detailed images of the brain's structure and tracks blood flow and oxygen levels, allowing comparisons between healthy individuals and those with psychological disorders.
