Neuropsychology studies how the anatomy of the brain affects someone’s behavior, emotion, and cognition.Over the years, brain scientists have shown that different parts of the brain are responsible for specific functions, whether it’s recognizing colors or problem solving. Contrary to the ten-percent myth, scientists have proven that every part of the brain is integral for our daily functioning thanks to brain imaging techniques like positron emission tomography and functional magnetic resonance imaging.Research has yet to find a brain area that is completely inactive. Even studies that measure activity at the level of single neurons have not revealed any inactive areas of the brain. Many brain imaging studies that measure brain activity when a person is doing a specific task show how different parts of the brain work together.For example, while you are reading this text on your smartphone, some parts of your brain, including those responsible for vision, reading comprehension, and holding your phone, will be more active.Some brain images, however, unintentionally lend support to the ten-percent myth because they often show small bright splotches on an otherwise gray brain. This may imply that only the bright spots have brain activity, but that isn’t the case.Rather, the colored splotches represent brain areas that are more active when someone’s doing a task compared to when they’re not, with the gray spots still being active but to a lesser degree.A more direct counter to the ten-percent myth lies in individuals who have suffered brain damage – like through a stroke, head trauma, or carbon monoxide poisoning – and what they can no longer do, or do as well, as a result of that damage. If the ten percent myth is true, then damage to many parts of our brain shouldn’t affect your daily functioning.Studies have shown that damaging a very small part of the brain may have devastating consequences. If someone experiences damage to Broca’s area, for example, they can understand language but can’t properly form words or speak fluently.In one highly publicized case, a woman in Florida permanently lost her “capacity for thoughts, perceptions, memories, and emotions that are the very essence of being human” when a lack of oxygen destroyed half of her cerebrum – which makes up about 85 percent of the brain.
