Summary: Researchers outline a range of neurotechnology uses—from criminal monitoring and workplace surveillance to metaverse interaction and cognitive enhancement—and discuss the legal, ethical and regulatory challenges these developments raise.

Dr Allan McCay, a criminal law scholar at the University of Sydney Law School, has published the first comprehensive overview of neurotechnology and its legal implications for courts, lawyers and policy makers.
Neurotechnology refers to devices and systems that interface directly with the brain or the wider nervous system. These technologies can record neural activity, monitor brain states, or actively influence neural function. They range from implanted devices to external hardware such as headsets, wristbands or helmets.
Clinically, neurotech is already established in treating movement disorders and epilepsy and shows promise for managing conditions such as schizophrenia, depression and anxiety. Beyond health care, however, the same capabilities invite use in settings such as criminal justice, the workplace, defence, entertainment and the emerging metaverse.
Potential non-medical applications include continuous monitoring of offenders, cognitive enhancement that could create social or professional divides between enhanced and non-enhanced people, workforce monitoring for productivity or safety, military use that augments soldier capabilities, and new forms of human-computer interaction for gaming or virtual environments.
Dr McCay warns that these advances require urgent legal and ethical attention. Commercial actors and technology investors are already pursuing neurotech opportunities, so regulatory frameworks and governance principles should be developed now rather than after harms appear. Decisions are needed at societal and corporate levels about acceptable uses, data governance, consent and human rights protections.
The world-first report, Neurotechnology, law and the legal profession, was commissioned by the Law Society of England and Wales.
Key legal and policy questions highlighted in the report include:
- Could an external device, such as a brain-monitoring bracelet, or an implanted system be used to track or influence an offender’s mental states?
- Could monitoring systems detect impulsive or dangerous thoughts and trigger interventions—technical, medical or legal?
- If a device is compromised, could a defendant claim their brain or neural device was hacked, and how would responsibility be attributed?
- When does a thought become an act? If neural activity leads to a physical crime, how should liability and punishment be determined?
- Might courts order continuous brain monitoring as a condition of community-based sentences or parole?
- Who controls neural data collected by these systems, how is it stored, and what protections ensure it is not misused?
- Do individuals have a right to mental or brain privacy, and how should law protect against intrusive access by corporations or states as predictive technologies improve?
- Could legal firms monitor or enhance lawyers’ cognition for productivity, and would billing models shift from hours to “units of attention” or similar metrics?
- Will lawyers adopt neurotechnology to remain competitive with AI-driven legal services, and what ethical constraints would apply?
Dr McCay emphasizes that governance must keep pace with innovation. He notes significant investors and companies involved in neurotechnology development, including figures and firms such as Elon Musk and Meta (Facebook), and calls for law reform bodies, policy makers and academics to scrutinize these technologies proactively.
To illustrate the kinds of legal puzzles neurotech poses, Dr McCay asks how traditional criminal law concepts apply when conduct originates in neural commands. For example, if a person uses thought alone to pilot a drone that causes injury, which element of conduct constitutes the actus reus? It is relatively straightforward to characterise physical manipulation, such as using a joystick, but neural control challenges existing categories.
Similar difficulties arise at sentencing and in corrections: would it be acceptable to monitor or intervene in offenders’ brains while they serve community sentences? These possibilities raise serious human rights concerns and prompt debate over whether current human rights protections are adequate to address brain monitoring, manipulation and the wider effects on privacy, autonomy and dignity.
