  1. The Case Against Organoid Consciousness.Tim Bayne & James Croxford - 2024 - Neuroethics 17 (1):1-15.
    Neural organoids are laboratory-generated entities that replicate certain structural and functional features of the human brain. Most neural organoids are disembodied—completely decoupled from sensory input and motor output. As such, questions about their potential capacity for consciousness are exceptionally difficult to answer. While not disputing the need for caution regarding certain neural organoid types, this paper appeals to two broad constraints on any adequate theory of consciousness—the first involving the dependence of consciousness on embodiment; the second involving the dependence of (...)

  • Global Versus Local Theories of Consciousness and the Consciousness Assessment Issue in Brain Organoids.Maxence Gaillard - 2024 - Neuroethics 17 (1):1-14.
    Any attempt at consciousness assessment in organoids requires careful consideration of the theory of consciousness that researchers will rely on when performing this task. In cognitive neuroscience and the clinic, there are tools and theories used to detect and measure consciousness, typically in human beings, but none of them is neither fully consensual nor fit for the biological characteristics of organoids. I discuss the existing attempt relying on the Integrated Information Theory and its models and tools. Then, I revive the (...)

  • The Future of Human Cerebral Organoids: A Reply to Commentaries.Andrea Lavazza & Federico Zilio - 2023 - American Journal of Bioethics Neuroscience 14 (4):W1-W4.
    Human brain organoids (HCOs) are laboratory-grown biological entities that have been added to the catalog of living entities for just over a decade. How they are formed and may continue to develop for some time is not irrelevant, given their peculiarity, which is that they mimic the human brain with a high degree of similarity. Revolving around this key issue is the discussion on our target article (Zilio and Lavazza 2023), for which we are grateful to all the commentators.

  • Theoretical Neurobiology of Consciousness Applied to Human Cerebral Organoids.Matthew Owen, Zirui Huang, Catherine Duclos, Andrea Lavazza, Matteo Grasso & Anthony G. Hudetz - forthcoming - Cambridge Quarterly of Healthcare Ethics:1-21.
    Organoids and specifically human cerebral organoids (HCOs) are one of the most relevant novelties in the field of biomedical research. Grown either from embryonic or induced pluripotent stem cells, HCOs can be used as in vitro three-dimensional models, mimicking the developmental process and organization of the developing human brain. Based on that, and despite their current limitations, it cannot be assumed that they will never at any stage of development manifest some rudimentary form of consciousness. In the absence of behavioral (...)

  • Human Brain Organoids: Why There Can Be Moral Concerns If They Grow Up in the Lab and Are Transplanted or Destroyed.Andrea Lavazza & Massimo Reichlin - 2023 - Cambridge Quarterly of Healthcare Ethics 32 (4):582-596.
    Human brain organoids (HBOs) are three-dimensional biological entities grown in the laboratory in order to recapitulate the structure and functions of the adult human brain. They can be taken to be novel living entities for their specific features and uses. As a contribution to the ongoing discussion on the use of HBOs, the authors identify three sets of reasons for moral concern. The first set of reasons regards the potential emergence of sentience/consciousness in HBOs that would endow them with a (...)

    Human brain organoids are three-dimensional masses of tissues derived from human stem cells that partially recapitulate the characteristics of the human brain. They have promising applications in many fields, from basic research to applied medicine. However, ethical concerns have been raised regarding the use of human brain organoids. These concerns primarily relate to the possibility that brain organoids may become conscious in the future. This possibility is associated with uncertainties about whether and in what sense brain organoids could have consciousness (...)

    Advances in research on human cerebral organoids (HCOs) call for a critical review of current research policies. A challenge for the evaluation of necessary research regulations lies in the severe uncertainty about future trajectories the currently very rudimentary stages of neural cell cultures might take as the technology progresses. To gain insights into organotypic cultures, ethicists, legal scholars, and neuroscientists rely on resemblances to the human brain. They refer to similarities in structural or functional terms that have been established in (...)
