Briefing
Debate about neurotechnology and the protection of so-called neurodata is intensifying in Spain. International developments now provide concrete points of reference: on 11 November 2025 the UNESCO adopted the Recommendation on the Ethics of Neurotechnology, which sets minimum standards for the ethical use of brain technologies, transparency obligations and bans on coercive applications. Since then, the recommendation has served as a reference framework for governments and supervisory authorities.
At the same time, Spain’s data protection authority, AEPD has taken a more active role: in June 2026, the AEPD reported the adoption of a document by the Red Iberoamericana de Protección de Datos (RIPD), calling for stronger safeguards for the processing of neurodata in non-medical settings. This initiative highlights that existing data-protection categories are often not directly sufficient to address risks such as re-identification, misuse of data or informed consent in invasive procedures.
In Spain, scientists, ethicists and politicians are raising similar key questions: which data belong to the specially protected mental sphere, how should consent, purpose limitation and retention periods be regulated, and how can misuse – such as discrimination or indirect coercion – be prevented? Voices from research and business stress the therapeutic benefits of brain-computer interfaces for conditions such as Parkinson’s or in rehabilitation; at the same time, data protection authorities and ethicists are calling for strict safeguards.
Prominent voices in the debate, including neurobiologist Rafael Yuste, have shaped the concept of “neurorights” and helped foster public debate. Universities and civil society platforms are organising information and dialogue events to develop rules balancing research, clinical practice and the protection of fundamental rights.
To date, Spain has no comprehensive national laws specifically tailored to neurotechnology; recommendations, position papers and requests for review predominate. In light of the guiding principles set out in the UNESCO text and Ibero-American recommendations, the challenge will be to reconcile scientific progress with the guarantees of the rule of law and establish mental privacy as a distinct area of protection.
