The rise of neurotechnology—the intersection of neuroscience and technology—has brought us closer than ever to the possibility of recording, interpreting, and even manipulating neural data. Neural data refers to the electrical activity generated by our brains, which can be captured through technologies like brain-computer interfaces (BCIs), electroencephalography (EEG), and functional magnetic resonance imaging (fMRI). These technologies can decode our thoughts, emotions, intentions, and other cognitive states, creating new opportunities for medical treatments, communication devices for those with disabilities, and even brain-based enhancements for healthy individuals.
However, as the potential to record and interpret brain activity grows, so too does concern about the privacy and security of our most personal data: our thoughts. Some experts argue that neural data should be subject to stronger legal protections to prevent misuse, including unauthorized access, manipulation, or exploitation of an individual’s thoughts.
What is Neural Data?
Neural data is essentially any type of information generated by the brain’s electrical activity, and it can be collected using various technologies:
- Brain-Computer Interfaces (BCIs): Devices that measure and interpret neural signals to allow communication or control of devices like computers or prosthetics. BCIs have been particularly transformative for people with paralysis, allowing them to control their environment through thought alone.
- Electroencephalography (EEG): A non-invasive technique that measures the electrical activity of the brain. EEG is often used in medical settings to monitor brain health, but it can also be used for research into cognitive states and intentions.
- Functional Magnetic Resonance Imaging (fMRI): A brain imaging technique that measures brain activity by detecting changes in blood flow, which can be used to infer neural activity related to specific thoughts, feelings, or behaviors.
The Risks and Ethical Concerns
As these technologies advance, they raise critical concerns about privacy, consent, and the potential for neural surveillance. Key ethical risks include:
- Invasions of Privacy: Neural data could reveal sensitive information about a person’s thoughts, memories, and intentions—far beyond what they might disclose willingly. This raises fears about unauthorized access, especially if this data is used for commercial or political purposes.
- Cognitive Manipulation: There are fears that the data could be used to influence people’s thoughts or decisions, leading to neural manipulation or brainwashing. For instance, advertising or political campaigns might use knowledge of an individual’s brain patterns to manipulate their behavior.
- Discrimination: Neural data could be misused for discriminatory purposes, such as profiling individuals based on brain activity associated with mental health conditions or cognitive states. Employers or insurers could use this data to make biased decisions.
- Security Concerns: As with any data, neural data could be subject to cyberattacks. If brain activity is hacked, malicious actors could manipulate or exploit individuals by altering their neural patterns or collecting private thoughts.
Protections for Neural Data in the EU
The European Union has taken significant steps to address these concerns through its robust data protection regulations, particularly the General Data Protection Regulation (GDPR), which is one of the most comprehensive privacy frameworks in the world. However, as neurotechnologies evolve, there are calls to strengthen protections around neural data specifically.
1. GDPR and Data Privacy
Under the GDPR, personal data is any information that can identify a person, and this includes neural data if it can be linked to an individual. The regulation grants individuals significant rights over their personal data, including the right to:
- Access: Individuals can request information on what personal data is being collected and how it is used.
- Rectification: The right to correct inaccuracies in the data.
- Erasure: The right to have personal data deleted in certain circumstances (e.g., when it is no longer needed).
- Data Portability: The right to transfer personal data between service providers.
The GDPR also classifies some types of data as “sensitive personal data,” including health-related data. If neural data is used for medical purposes or to assess cognitive or mental health, it could fall under this category, which provides additional protection (e.g., requiring explicit consent for processing).
2. Explicit Consent and Transparency
For neural data to be processed under the GDPR, explicit consent from the individual is required, particularly when the data is used for purposes like medical treatment, research, or any kind of cognitive monitoring. This ensures that individuals are fully informed about how their neural data is being used and can decide whether they want to share it.
3. The EU’s Artificial Intelligence (AI) Act
The EU is also working on the Artificial Intelligence (AI) Act, which could include specific provisions on how AI technologies—such as those used in neurotechnology—are deployed. The act aims to ensure that AI systems are developed and used in a way that is safe, ethical, and respects fundamental rights, including privacy and non-discrimination.
The AI Act categorizes AI systems based on risk, with high-risk systems subject to stricter oversight. While neural data is not explicitly mentioned, BCIs and neurotechnologies could be considered high-risk due to their potential for abuse or significant impact on privacy. This could lead to additional regulations on how neural data is collected, stored, and used.
4. The EU Charter of Fundamental Rights
The EU Charter of Fundamental Rights guarantees the right to privacy and protection of personal data. This includes the protection of an individual’s private life, which extends to their mental integrity and cognitive privacy. The right to privacy could be extended to neural data to prevent unauthorized access to an individual’s brain activity.
Calls for Greater Protection
Despite these existing protections, some experts and privacy advocates argue that neural data requires more specific and robust protections due to its unique and highly personal nature. Neural data isn’t just “data”—it is a direct reflection of our thoughts, emotions, and even subconscious processes, which makes it deeply intimate.
Some argue that existing privacy laws, such as the GDPR, may not fully account for the complexities of neurotechnologies, particularly as they become more sophisticated. Proposals for new legislation and regulatory frameworks that specifically address neural privacy are gaining traction. These could include:
- Stronger safeguards around the use of brain data, ensuring it is not exploited for commercial gain or political manipulation.
- Increased transparency about how neural data is used and shared, with more emphasis on informed consent.
- Special protections for vulnerable groups, such as those with mental health conditions, who may be more at risk of having their neural data misused or misinterpreted.
Conclusion
As neural data becomes increasingly accessible and actionable, it is essential that the EU continues to lead the way in safeguarding individual privacy and ensuring that technologies are developed in a responsible and ethical manner. While the GDPR and other regulations provide a strong foundation, further legal protections will be needed to address the unique challenges posed by neurotechnology, ensuring that our most private thoughts and cognitive states remain protected from exploitation or misuse.
