Brain–Computer Interface (BCI):
India is exploring neurotechnology and Brain–Computer Interfaces (BCIs) as strategic tools for healthcare, economic growth, and technological leadership amid global advances led by the U.S., China, and Europe.A Brain–Computer Interface (BCI) is a system that interprets brain signals and converts them into digital commands to control external devices such as computers, robotic limbs, or wheelchairs.
BCIs form a two-way communication channel between the brain and machines, aiding restoration of lost functions or enabling new capabilities.Electrodes (invasive or non-invasive) record electrical activity from neurons Machine learning algorithms translate these patterns into intentions (e.g., move arm, select letter).The decoded signals activate an external device—robotic limbs, speech synthesizers, drones, or smart-home systems. Continuous decoding improves accuracy and enables real-time brain-machine interaction.
