What is a brain-computer interface (BCI)?
A brain-computer interface is a direct communication pathway between the brain's electrical activity and an external device, such as a computer or robotic limb.
When did research on BCIs begin?
Research on BCIs began in the 1970s by Jacques Vidal at the University of California, Los Angeles (UCLA) under a grant from the National Science Foundation, followed by a contract from DARPA.
What are the different types of BCI implementations mentioned in the text?
Implementations of BCIs range from non-invasive (EEG, MEG, MRI) and partially invasive (ECoG and endovascular) to invasive (microelectrode array), based on how close electrodes get to brain tissue.
