Brain-computer interface: Difference between revisions

A BCI output could enhance natural CNS output. For example, as a method to prevent the loss of attention when someone is engaged in a task that requires constant focus. A BCI could detect the brain activity that precedes break in attention and create an output (a sound for example) that would alert the person. It could also supplement natural CNS output, such as in the case of a person that uses a BCI to control a third robotic arm, for example, or to choose items when a user that is controlling the position of the cursor selects them. In these cases the BCI supplements the natural neuromuscular output with another, the artificial output. Finally, the BCI output could improve the natural CNS output. As an example, a person whose arm movements are compromised by a sensorimotor cortex damaged by a stroke could use a BCI system to measure signals from the damaged areas and then excite muscles or control an orthosis that would improve arm movement <ref name=”3”></ref>.
