Existential risk assessment for advanced neurotech systems

Introduction

Advanced neurotechnology refers to technologies that interact directly or indirectly with the human nervous system to monitor, interpret or influence brain activity. These systems include brain-computer interfaces (BCIs), neural implants, neurostimulation devices, artificial intelligence-based brain monitoring tools and advanced neuroprosthetics.

Existential risk assessment for advanced neurotechnology involves examining whether the development or misuse of such systems could create threats to human survival, human autonomy, social stability or fundamental rights on an exceptionally large scale. Although most present-day neurotechnology applications are designed for medical and scientific purposes, future systems may raise serious concerns involving mental privacy, cognitive liberty, manipulation, cybersecurity and human control over technological systems.

The objective of legal regulation is therefore to encourage beneficial innovation while preventing potentially irreversible harm.

Meaning and scope of existential risk assessment

Existential risk assessment is a systematic process for identifying and evaluating threats that could permanently damage humanity's ability to maintain its existence or fundamental conditions of civilisation.

In advanced neurotechnology, such assessment extends beyond ordinary medical safety evaluation. It examines risks arising from increasingly powerful systems capable of collecting neural information, influencing cognitive processes or connecting human nervous systems with artificial intelligence.

Important areas include:

Unauthorised access to neural information.

Manipulation of cognitive processes through neurostimulation.

Loss of individual autonomy and mental privacy.

Large-scale cybersecurity attacks involving connected neural devices.

Excessive dependence on automated decision-making.

Military or coercive applications of neurotechnology.

Unequal access and potential discrimination based on neural information.

Not every neurotechnology risk is existential. Many are individual, medical or societal risks. However, interconnected systems deployed at a large scale may create broader systemic threats.

Major legal and ethical concerns

1. Mental privacy and cognitive liberty

Advanced neurotechnology may collect information about brain activity, attention, emotional responses and certain cognitive patterns. Such information can reveal highly personal details.

Unauthorised access or commercial exploitation may interfere with individual privacy and personal autonomy. Therefore, neural data should receive strong protection through informed consent, purpose limitation and secure processing.

2. Manipulation and human autonomy

Neurostimulation technologies may influence neurological activity for therapeutic purposes. However, their misuse could raise concerns about coercion, behavioural manipulation and interference with independent decision-making.

Legal safeguards should ensure that individuals retain meaningful control over interventions affecting their nervous systems.

3. Cybersecurity and systemic risks

Connected neural devices may depend on software, wireless communication and cloud-based systems. Weak cybersecurity could expose sensitive information or interfere with device functioning.

Large-scale dependence on interconnected neurotechnology creates additional risks if software vulnerabilities or coordinated attacks affect multiple systems.

4. Military and national security applications

Neurotechnology may have applications in military medicine, human performance research and defence-related activities. However, using neural technologies for coercive interrogation, behavioural control or involuntary experimentation raises serious human rights concerns.

Regulation must distinguish legitimate medical applications from harmful or non-consensual uses.

Legal framework in India

1. Article 21 of the Constitution

Article 21 protects life and personal liberty. Its interpretation includes privacy, dignity and personal autonomy.

The constitutional framework is relevant to neurotechnology because interventions affecting brain activity may directly influence bodily integrity and individual decision-making. Any state action involving such technology must satisfy applicable constitutional requirements.

2. Digital Personal Data Protection Act, 2023

The DPDP Act regulates the processing of digital personal data. Neural information linked to an identifiable individual may fall within its scope.

The Act provides obligations concerning lawful processing, security safeguards and individual rights. However, it does not establish a separate comprehensive legal category for neural data. Its application must also be considered alongside commencement notifications and applicable rules.

3. Information Technology Act, 2000

The Information Technology Act addresses several forms of unauthorised access, data-related misconduct and cyber offences. Its provisions may become relevant where connected neurotechnology systems are compromised or sensitive digital information is unlawfully accessed.

4. Medical Devices Rules, 2017

Neurotechnology products intended for medical purposes may fall within the medical-device regulatory framework. Depending on their classification and intended use, they may require licensing, quality controls, safety evaluation and post-market monitoring.

5. Biomedical research ethics

The ICMR National Ethical Guidelines for Biomedical and Health Research Involving Human Participants, 2017, provide principles concerning informed consent, participant protection, risk assessment and Ethics Committee oversight.

These principles are particularly important for experimental neural implants and research involving direct intervention in brain activity.

Important case laws

1. Justice K.S. Puttaswamy v. Union of India (2017)

The Supreme Court recognised privacy as a fundamental right under the Constitution. The judgment is highly relevant to neurotechnology because neural information may reveal intimate details about an individual's mental and physical condition. It supports strong safeguards against unnecessary collection, processing and disclosure of such information.

2. Selvi v. State of Karnataka (2010)

The Supreme Court examined the constitutionality of involuntary narcoanalysis, polygraph examinations and brain electrical activation profile tests. It held that involuntary administration of these techniques violated constitutional protections, including Article 20(3) and Article 21. This decision is particularly important for protecting mental privacy and preventing coercive use of neurotechnology.

3. Samira Kohli v. Dr. Prabha Manchanda (2008)

The Supreme Court explained the importance of informed consent in medical treatment. The judgment is relevant to invasive neurotechnology because patients must receive appropriate information about proposed interventions, their risks and available alternatives before consenting.

4. Common Cause v. Union of India (2018)

The Supreme Court recognised the importance of individual autonomy and dignity in end-of-life medical decisions. Its reasoning supports the broader principle that medical technologies must respect individual choice and personal dignity.

5. A.P. Pollution Control Board v. Prof. M.V. Nayudu (1999)

The Supreme Court highlighted the importance of scientific expertise when courts and regulators deal with complex risks and scientific uncertainty. Although the case concerned environmental regulation, its precautionary reasoning is relevant by analogy to emerging neurotechnology systems whose long-term consequences may not be fully understood.

Risk assessment and regulatory safeguards

A comprehensive assessment should examine the entire lifecycle of a neurotechnology system, from research and development to commercial deployment and eventual discontinuation.

The following safeguards are particularly important:

Independent scientific and ethical review before human experimentation.

Strong informed-consent procedures.

Encryption and restricted access to neural datasets.

Independent cybersecurity testing.

Continuous monitoring of adverse effects.

Clear accountability for manufacturers and healthcare providers.

Emergency procedures for system failure.

Periodic reassessment of long-term societal risks.

Regulators should also consider whether certain applications require prohibition or stricter restrictions because they create unacceptable threats to human dignity and autonomy.

International developments

The UNESCO Recommendation on the Ethics of Neurotechnology, adopted in 2025, provides an important international framework for responsible neurotechnology development. It addresses human rights, mental privacy, informed consent, safety and equitable access.

The OECD Recommendation on Responsible Innovation in Neurotechnology, adopted in 2019, also encourages responsible research, transparency, safety and public engagement.

These frameworks are influential policy instruments but do not automatically operate as binding domestic legislation in India.

Conclusion

Existential risk assessment for advanced neurotechnology is essential for ensuring that scientific progress does not undermine human dignity, autonomy and security. Indian constitutional principles, particularly Articles 21 and 20(3), provide important protections against coercive technological interventions. Decisions such as Puttaswamy and Selvi establish valuable foundations for protecting mental privacy and personal liberty. A forward-looking regulatory framework should combine scientific evaluation, ethical oversight, cybersecurity safeguards and meaningful human control to ensure that advanced neurotechnology develops responsibly.
