Question

Quizplus · Accepted Answer

PET and fMRI brain scans do not show that most people use only 10 percent of their brain capacity. This is a popular myth that has been debunked by scientific research. Both PET and fMRI scans provide images of brain activity, but they do not show overall brain capacity or usage. Researchers are working on creating digital brain maps that show both brain structures and their associated functions, but this technology is still in development and is not yet widely available. However, fMRI images have been used in experiments to detect lying, and both fMRI and PET scans are important tools for studying the brain.
