New brain mapping method reveals links between brain activity and behavior

Researchers at the University of Birmingham have developed a new method for mapping brain activity that reveals how complex interactions among multiple brain regions contribute to higher-order functions like thought and language. This approach differs from traditional models that only examine pairwise connections. The new method was validated using fMRI data from 100 subjects, successfully identifying tasks, creating unique brain "fingerprints," and linking brain activity to individual behaviors. This advancement enhances understanding of brain function and could aid in studying neurodegenerative diseases. The findings were published in *Nature Communications*. The research demonstrates significant improvements in analyzing brain interactions, offering insights that traditional methods may overlook.
