Invasive vs. Non-Invasive Brain-Computer Interfaces: The Signal-Risk Trade-Off That Shapes Medical Use

Brain-computer interfaces (BCIs) present a fundamental trade-off between signal quality and risk, dictating their medical applications. Invasive BCIs offer superior signal resolution for precise control but require surgery, while non-invasive systems are safer but yield lower fidelity, making the choice dependent on specific healthcare needs.
