How can we study the brain without causing any harm?
In short: Within our solar system, the human brain remains the sole entity complex enough to conduct its own study. This video explores how scientists use tools like EEGs, fMRIs, and PET scans to investigate the brain's billions of cells without harming the person.
Investigating a living brain presents unique challenges because it is protected by the skull and wrapped in tissue. To understand how these complex systems function, researchers must use non-invasive methods.
This video examines the mechanics behind key neuroimaging technologies, including electroencephalography (EEG), functional magnetic resonance imaging (fMRI), and positron emission tomography (PET), which allow us to observe neural activity safely.
