From UPSC perspective, the following things are important :
Prelims level: Neuralink
Mains level: Not Much
Central Idea
- Elon Musk’s brain implant company Neuralink has announced it is one step closer to putting brain implants in people.
Neuralink’s Vision
- Neuralink uses tiny brain implants to control neural signals for movement.
- These implants translate thoughts into actions via a wireless app.
Science behind Brain-Computer Interfaces (BCIs)
- They use a tiny chip implanted in the brain.
- This chip reads and sends brain signals to an app, turning thoughts into actions.
- It starts with helping paralyzed individuals control a computer cursor using their thoughts.
- Some BCIs use sensor-filled structures like hairnets to detect brain signals.
- They can stimulate different parts of the brain, which showed promise in treating conditions like depression.
India’s Role in Brain Tech
- C-DAC in India is developing BCIs to capture brain signals that show intentions.
- The All India Institute of Medical Sciences is testing this project.
- BrainSight AI, an Indian startup, maps brain connections to understand neurological conditions.
Indian Innovations and Their Impact
- Indian BCIs, like Neuralink’s, aim to help paralyzed patients move and communicate.
- They could also treat mental disorders like schizophrenia.
- Indian hospitals are testing these technologies.
Challenges Ahead
- Invasive BCIs, like Neuralink’s, face rules and need lots of data.
- Non-invasive BCIs are moving faster.
- Indian institutions are actively testing these technologies and mapping the brain.
