Brain-Computer Interfaces

Brain-computer interfaces (BCI) allow communication between the brain and external devices using electroencephalography (EEG) to measure brain activity. BCIs can help patients with neuromuscular disorders by using remaining brain pathways to provide new channels for communication and control. Non-invasive BCIs use EEG electrodes placed on the scalp to detect patterns in frequency bands associated with events like movements to control devices. Invasive BCIs are implanted in the brain but non-invasive options avoid risks of surgery.
