Summary:
- This article discusses a new technology called "brain-computer interfaces" (BCIs) that allow direct communication between the brain and external devices.
- BCIs work by detecting and interpreting electrical signals from the brain, which can then be used to control or interact with computers, robots, or other technologies.
- The article explains how BCIs have the potential to revolutionize fields like healthcare, education, and entertainment, by enabling people to control devices using only their thoughts.
