Syllabus: Science and Technology — developments and their applications and effects in everyday life.
What is Neurotechnology?
- Neurotechnology refers to mechanical or digital tools that interact directly with the brain.
- It includes systems that record, decode, stimulate, or influence neural activity.
- Core element is the Brain–Computer Interface (BCI), translating neural signals into digital commands for computers, prosthetics, or mobility devices.
- BCIs may be non-invasive (EEG headsets) or invasive (implanted electrodes enabling precise control).
- Applications include diagnostics, neuroprosthetics, movement restoration, treatment of depression/Parkinson’s, and cognition studies.
Current and Potential Applications
- Assists paralysed individuals by enabling movement of robotic limbs.
- Stimulates neural circuits for mental health therapy, reducing long-term medication dependence.
- Enables rehabilitation after stroke or spinal injuries.
- Experimental research includes brain-to-brain communication in animals, showing future possibilities of enhanced cognition or military use (subject to ethics).
Why Does India Need Neurotechnology?
- India faces a high neurological disease burden, with rising non-communicable and injury-related neurological disorders (1990–2019).
- Stroke is India’s largest neurological contributor to DALYs.
- Neurotech offers prospects for mobility restoration, communication aids, and targeted therapy for millions.
- Economic potential exists at the intersection of AI, biotechnology, biomedical engineering, where India has emerging capabilities.
India’s Current Position
- IIT Kanpur developed a BCI-enabled robotic hand aiding stroke patients.
- National Brain Research Centre (Manesar) and IISc Brain Research Centre lead research.
- Start-up innovations include Dognosis, studying neural patterns in dogs to advance cancer detection techniques.
- Growing academic–industry ecosystem supports India’s potential role as a neurotechnology hub.
Global Developments
- U.S. BRAIN Initiative accelerates neurotech innovation.
- Neuralink trials show BCIs restoring motor function in paralysed patients.
- China Brain Project (2016–2030) integrates cognition studies with AI and clinical neuroscience.
- EU and Chile pioneering laws on neurorights, data protection, and cognitive liberty.
Policy and Ethical Requirements for India
- Need for clear regulatory pathways tailored to different types of BCIs.
- Framework must ensure data privacy, user autonomy, ethical oversight, and medical safety.
- Public engagement strategies essential for addressing risks, benefits, and societal expectations.
Conclusion
- Neurotechnology offers major opportunities in healthcare, industry, AI, disability support, and national innovation capacity.
- With strong research institutions and genetic diversity, India can emerge as a global neurotech leader—provided regulation evolves alongside innovation.
