TED-ED: How do we study living brains? - John Borghi and Elizabeth Waters

The video explores the complexity of studying the human brain, highlighting three key techniques: EEG, fMRI, and PET. EEG measures electrical activity and is fast but lacks spatial precision. fMRI provides detailed spatial information by tracking oxygen consumption but is slower. PET offers chemical insights using radioactive tracers but has the lowest time resolution. These methods help link brain activity to behavior, though they are limited by current technology. Future advancements may improve our understanding of brain functions and diseases like Alzheimer's.
