Mind-Reading Devices Are Revealing the Brain's Secrets

scientists have studied how brain-computer interfaces, such as this non-invasive cap, change brain activity

Although the main impetus behind the development of brain-computer interfaces is to help restore functions to paralyzed people, the technology also provides a unique way to explore how the human brain is organized.

Although the primary goal of brain-computer interfaces (BCIs) is to help patients with paralysis regain certain functions, BCIs are helping researchers learn more about brain anatomy.

For instance, Stanford University researchers found that a region of the brain thought to play a role in speech production and articulation contained little to no information about words, facial movements, or units of sound.

Meanwhile, researchers at the Netherlands' Maastricht University discovered that people who cannot speak may still be able to use a BCI by imagining speech.
