    Hervé Chneiweiss, Research Director au CNRS, Neuro-Oncologist à l'Hôpital Universitaire Pitié-Salpêtrière, Président du comité d'éthique de l'Inserm

    Since 2015, the OECD has convened a panel of experts to develop a framework for responsible research and innovation in the field of neurotechnologies. This effort culminated in Recommendation 457 in 2019. In France, this recommendation has been implemented through the development of a Charter, which is poised to become European-wide. Additionally, an interactive toolkit has been recently introduced. Concurrently, the UNESCO International Bioethics Committee released a report in 2021 on the ethical implications of neurotechnologies. These findings serve as the foundation for ongoing efforts to adopt a recommendation in 2025, which will serve as legislative groundwork for member states. We will compare and contrast the approaches of both organizations, in which we have actively participated.

    Hervé Chneiweiss (MD-PhD) is a neurologist and neuroscientist, senior scientist at CNRS, he has been involved in neurogenetic research on diseases such as cerebellar ataxias and then the molecular mechanisms involved in astrocyte phenotype and plasticity, and the development of brain tumors, their epigenetic and metabolic drivers. Technical approaches include proteomics, metabolism, epigenetics, cell cultures, animal models, single cell. He has published over 170 original scientific papers (h=55, i10 112). He is currently director of the Neuroscience Paris Seine-IBPS research center (CNRS/Inserm/Sorbonne University). Hervé Chneiweiss is also involved in bioethics, adviser for life sciences and bioethics to the Minister of Research and Technology (2000-02), member of the Scientific Council of the French Parliamentary Office for Scientific and Techniques assesment (2003-16), member of the French National Ethics Committee (2013-17), member and chairman of the UNESCO International Bioethics Committee (2014-21), member of the WHO committee on Human genome governance (2019-21), expert for OECD on neurotechnology (since 2015), and currently as chairman of the Inserm Ethics Committee, EMBL Ethics Board, EBRAINS EESC and co-chair AHEG UNESCO for recommendation on neurotechnologies. Former editor in chief of Medicine/Sciences (2006-16). He has published several books for the general public (latest: Notre cerveau, L'Iconoclaste, 2019).

    As neurotechnologies transition from research labs to mainstream markets, they encounter a complex array of ethical considerations, regulatory frameworks, and market dynamics. The ethical and regulatory responses to the swift deployment of AI-powered neurotech are continually evolving. In this presentation, Oullier will build on his expertise in academia, policymaking, and business to champion proactive engagement with all stakeholders. This approach aims to ensure that the commercial expansion of neurotechnologies aligns with societal values and ethical principles, enhancing human capabilities while safeguarding fundamental rights. Additionally, he will address the risks posed by unregulated commercial practices as well as by poorly informed individuals involved in ethics and regulatory initiatives who are making non-evidence-based claims that could hinder both research and business progress in AI and neurotechnologies.

    Timothy Denison, Department of Engineering Science, University of Oxford

    The emerging field of bioelectronics provides a novel alternative to pharmaceutical intervention by using electronic hardware to intelligently sense and stimulate the nervous system.

    I will summarize the challenges and opportunities of translational bioelectronic systems face when bridging basic science, regulated technology, and health care economics – particularly for applications in paediatric medicine. This assessment motivates an innovation framework that leverages the unique capabilities of bioelectronic platforms -- from designing implantable scientific instruments that enable novel clinical neuroscience, to applying the resulting science to prototype new therapies. To provide an illustrative example of the platform and innovation framework, I will highlight experiences from the "Picostim-DyNeuMo," which is a collaborative, investigational research tool developed jointly by industry and academics. This system is targeting first-in-human clinical studies exploring challenging neurological disorders such as epilepsy, chronic pain, and disorders of consciousness, and the talk will emphasize the innovations required specifically for addressing paediatric epilepsy.

    Professor Denison holds a Royal Academy of Engineering Chair in Engineering Science and Clinical Neurosciences at Oxford, where he explores the fundamentals of physiologic closed-loop systems in collaboration with the MRC Brain Network Dynamics Unit. Tim serves as an advisor to several governments and industry boards on the field of translational medical devices; in particular, helping define strategies for mapping scientific discovery to product development roadmaps within the regulatory and economic constraints of medical systems. To support translation to the clinic, he is a director and chief engineer of Amber Therapeutics, which designs, manufactures, and distributes the Picostim-DyNeuMo investigational research system that is active in four first-in-human trials. Prior to joining Oxford, Tim was a Technical and Bakken Fellow at Medtronic PLC and Vice President of Research & Core Technology for the Restorative Therapies Group, where he helped oversee the design of next generation neural interface and algorithm technologies for the treatment of chronic neurological disease. In 2015, he was elected to the College of Fellows for the American Institute of Medical and Biological Engineering (AIMBE). He has an MS and PhD from MIT in electrical engineering, an AB in Physics and MBA from the University of Chicago.

    Résumé

    Des alternatives à l'électricité offrent de nouvelles opportunités pour la neuromodulation et la recherche en neurosciences, permettant des approches plus ciblées et parfois moins invasives.

    La stimulation magnétique utilise des champs magnétiques pour induire des courants électriques dans le cerveau. L'optogénétique combine la génétique et la lumière pour activer ou inhiber sélectivement l'activité neuronale. La neurostimulation acoustique utilise des ondes sonores ou ultrasons pour moduler l'activité ou permettre une ablation localisée d'une zone du cerveau sans endommager les structures adjacentes.

    Ces alternatives requièrent la mise au point de nouvelles technologies miniaturisées et multimodales.
