About Neurotechnology:

Neurotechnology encompasses all technologies developed to understand the brain, visualise its processes and even control, repair or improve its functions.

• Neurotechnology refers to technologies that:
  • Directly interact with the human brain and nervous system
  • Can record, interpret, stimulate, or modify neural activity
  • Combine neuroscience + AI + computing + bioengine

Example:

• Brain-Computer Interface (BCI):
  • A direct communication pathway between the brain and an external device
  • Converts brain signals into digital commands

Applications:

• Neuronal biofeedback:
  • Using real-time EEG (Electroencephalogram) or fMRI,(Functional magnetic resonance imaging ) someone can be taught to control their central nervous functions, such as heartbeat.
• Next generation neuropharmacology:
  • Behavioural and molecular neuropharmacology are benefiting from a better understanding of the nervous system to develop more effective drugs.
•  Neuroprostheses:
  • These devices are able to replace motor, sensory or cognitive abilities damaged as a result of injury or disease.
• Neural interfaces:
  • Brain-computer interfaces are fundamental in the development of new sensors and prostheses, allowing signals to be sent and received in real time.

Why Neurotechnology Matters for India:

India faces a triple challenge:

1. High neurological disease burden
2. Rising ageing population
3. Growing digital + defence ambitions

India’s Neurological Burden:

• Stroke, epilepsy, spinal cord injury, Parkinson’s, depression
• Rising mental health disorders
• High cost of long-term rehabilitation

BCIs can enable:

• Stroke and spinal injury patients to recover motor function
• Paralysed patients to move robotic or prosthetic limbs
• Locked-in patients to communicate using thought
• Parkinson’s patients to receive deep brain stimulation

Economic and Industrial Benefits for India:

• High-Value Industry Creation:
  • Indigenous medical device manufacturing
  • Neuro-AI startups
  • Brain-inspired computing (neuromorphic chips)
• Employment Generation:
  • Neuroscientists
  • Biomedical engineers
  • AI researchers
  • Data scientists
  • Rehabilitation specialists
• Global Market Leadership Opportunity:
  • Global neurotech market is expanding rapidly
  • India can replicate its success in:
    • IT services
    • Space (ISRO)
    • Generic pharmaceuticals
• Military and Strategic Applications:
  • Enhanced battlefield communication
  • Faster response systems using neural control
  • Fatigue monitoring of soldiers
  • Neuro-rehabilitation of injured soldiers

International Level initiative:

• Human Trials of Brain–Computer Interface (BCI) by Neuralink:
  • In 2024, Elon Musk’s company Neuralink received regulatory approval to conduct human brain implant trials.
  • A paralysed patient successfully used a BCI implant to control a computer with thoughts.
• Global Neurotechnology Race: USA vs China
  • USA is advancing under its BRAIN Initiative (NIH, DARPA).
  • China is aggressively funding its China Brain Project (2016–2030)

India:

• India’s Deep Tech Startup Policy, BioE3 Policy, and Startup India are encouraging:
• Medical devices
• AI in healthcare
• Brain–machine technologies
• IITs, IISc, AIIMS, NIMHANS are scaling neuro-AI and brain research.
• Neurotechnology is now seen as a “sunrise sector” for India.

Concerns related to Neurotechnology:

• Mental Integrity: Unlike many other frontier technologies, it can directly access, manipulate and emulate the structure of the brain. 
• Personal Identity & Psychological Continuity: Protection of one’s sense of self (compromises freedom of thought) and memory including autonomy and privacy from Memory modification or manipulation changing “who a person is”. 
• Use of Neural Data: Corporations might exploit neural data collected through neurotech devices for targeted marketing or commercial gain.
• Social Inequalities: Unequal deployment of neurotechnology could intensify existing social divides, potentially leading to greater social tension and conflict.

UNESCO Recommendations:

• Legal Protection and Regulation: Enact laws to control neurotechnology use, especially beyond scientific, medical, or judicial purposes.
• Data Policy: Develop robust, fair and agile regulatory and legal frameworks to govern the collection, processing, sharing and all other uses of neural data. 
• Equitable Access: Promote equitable access to science- and evidence-based, safe and reliable neurotechnology.
