In our article (Zawadzki and Adamczyk 2021), we analyzed threats that novel memory modifying interventions may pose in the future. More specifically, we discussed how optogenetics’ potential for reversible erasure/deactivation of memory “may impact authenticity by producing changes at different levels of personality.” Our article has received many thoughtful open peer commentaries for which we would like to express our great appreciation. We have identified two main threads of objections. They are related to the potential applicability of optogenetics as a (...) therapeutic memory modification technology (MMT) in humans—applicability thread, and the normative value of authenticity, that is, the assumption that preserving authenticity is valuable (either in general or in the particular approach we adopted)—normative thread. Both of these threads concern fundamental issues: The former deals with the scientific credibility of the case vignette on which our discussion is based, and the latter deals with the normative weight of our considerations. We think that addressing both of them can be instructive in a broader context as they reflect a more general disagreement among neuroethicists about the very purpose and method of our discipline.

This paper provides a justificatory rationale for recommending the inclusion of imagined future use cases in neurotechnology development processes, specifically for legal and policy ends. Including detailed imaginative engagement with future applications of neurotechnology can serve to connect ethical, legal, and policy issues potentially arising from the translation of brain stimulation research to the public consumer domain. Futurist scholars have for some time recommended approaches that merge creative arts with scientific development in order to theorise possible futures toward which current (...) trends in technology development might be steered. Taking a creative, imaginative approach like this in the neurotechnology context can help move development processes beyond considerations of device functioning, safety, and compliance with existing regulation, and into an active engagement with potential future dynamics brought about by the emergence of the neurotechnology itself. Imagined scenarios can engage with potential consumer uses of devices that might come to challenge legal or policy contexts. An anticipatory, creative approach can imagine what such uses might consist in, and what they might imply. Justifying this approach also prompts a co-responsibility perspective for policymaking in technology contexts. Overall, this furnishes a mode of neurotechnology’s emergence that can avoid crises of confidence in terms of ethico-legal issues, and promote policy responses balanced between knowledge, values, protected innovation potential, and regulatory safeguards.

Optogenetics is an invasive neuromodulation technology involving the use of light to control the activity of individual neurons. Even though optogenetics is a relatively new neuromodulation tool whose various implications have not yet been scrutinized, it has already been approved for its first clinical trials in humans. As optogenetics is being intensively investigated in animal models with the aim of developing novel brain stimulation treatments for various neurological and psychiatric disorders, it appears crucial to consider both the opportunities and dangers (...) such therapies may offer. In this review, we focus on the memory-modifying potential of optogenetics, investigating what it is capable of and how it differs from other memory modification technologies. We then outline the safety challenges that need to be addressed before optogenetics can be used in humans. Finally, we re-examine crucial neuroethical concerns expressed in regard to other MMTs in the light of optogenetics and address those that appear to be unique to the memory-modifying potential of optogenetic technology.

Brain-computer interfaces allow agents to control computers without moving their bodies. The agents imagine certain things and the brain-computer interfaces read the concomitant neural activity and operate the computer accordingly. But the use of brain-computer interfaces is problematic for criminal law, which requires that someone can only be found criminally responsible if they have satisfied the actus reus requirement: that the agent has performed some (suitably specified) conduct. Agents who affect the world using brain-computer interfaces do not obviously perform any (...) conduct, so when they commit crimes using brain-computer interfaces it is unclear how they have satisfied actus reus. Drawing on a forthcoming paper by Allan McCay, I suggest three potential accounts of the conduct that satisfies actus reus: the agent’s neural firings, his mental states, and the electronic activity in his brain-computer interface. I then present two accounts which determine how actus reus may be satisfied – one a counterfactual and the other a minimal sufficiency account. These accounts are lent plausibility because they are analogous to the but-for and NESS (Necessary Element in a Sufficient Set) tests for causation which are generally accepted tests for causation in legal theory. I argue that due to the determinations of these accounts and considerations regarding the relationship between the mind and brain, actus reus is satisfied by either the agent’s neural activity or brain-computer interface electrical activity. Which of these satisfies actus reus is determined by how well the brain-computer interface is functionally integrated with the agent. (shrink)

Lawrence and colleagues (2019) provide much-needed data in a topic area that is arguably overcrowded with ethical speculation but seldom populated by empirical data. The authors redirect us to the...

For nearly two decades, ethicists have expressed concerns that the further development and use of memory modification technologies (MMTs)—techniques allowing to intentionally and selectively alter memories—may threaten the very foundations of who we are, our personal identity, and thus pose a threat to our well-being, or even undermine our “humaneness.” This paper examines the potential ramifications of memory-modifying interventions such as changing the valence of targeted memories and selective deactivation of a particular memory as these interventions appear to be at (...) the same time potentially both most promising clinically as well as menacing to identity. However, unlike previous works discussing the potential consequences of MMTs, this article analyzes them in the context of the narrative relational approach to personal identity and potential issues related to autonomy. I argue that such a perspective brings to light the ethical aspects and moral issues arising from the use of MMTs that have been hidden from previously adopted approaches. In particular, this perspective demonstrates how important the social context in which an individual lives is for the ethical evaluation of a given memory-modifying intervention. I conclude by suggesting that undertaking memory modifications without taking into account the social dimension of a person’s life creates the risk that she will not be able to meet one of the basic human needs—the autonomous construction and maintenance of personal identity. Based on this conclusion, I offer some reflections on the permissibility and advisability of MMTs and what these considerations suggest for the future. (shrink)

Recent developments of three-dimensional printing of biomaterials in medicine have been portrayed as demonstrating the potential to transform some medical treatments, including providing new responses to organ damage or organ failure. However, beyond the hype and before 3D bioprinted organs are ready to be transplanted into humans, several important ethical concerns and regulatory questions need to be addressed. This article starts by raising general ethical concerns associated with the use of bioprinting in medicine, then it focuses on more particular ethical (...) issues related to experimental testing on humans, and the lack of current international regulatory directives to guide these experiments. Accordingly, this article considers whether there is a limit as to what should be bioprinted in medicine; examines key risks of significant harm associated with testing 3D bioprinting for humans; investigates the clinical trial paradigm used to test 3D bioprinting; analyses ethical questions of irreversibility, loss of treatment opportunity and replicability; explores the current lack of a specific framework for the regulation and testing of 3D bioprinting treatments.

What purpose can be served by empirically unsubstantiated speculation in ethics? In answering that question, we need to distinguish between the major branches of ethics. In foundational moral philosophy, the use of speculative examples is warranted to the extent that ethical principles and theories are assumed to be applicable even under the extreme circumstances referred to in these examples. Such an assumption is in need of justification, and it cannot just be taken for granted. In applied ethics, the use of (...) unrealistic scenarios is more difficult to justify. It can be positively harmful if it diverts our attention from more urgent issues. Neuroethics is one of the areas of applied ethics where speculative scenarios have taken up much of the attention that could instead have been devoted to problems that are relevant for the treatment and care of patients. Speculative ethics has often been defended with mere possibility arguments that may at first hand seem difficult to refute. It is shown with examples how such claims can be defeated with a combination of science and argumentation analysis. (shrink)

The idea that deep brain stimulation (DBS) induces changes to personality, identity, agency, authenticity, autonomy and self (PIAAAS) is so deeply entrenched within neuroethics discourses that it has become an unchallenged narrative. In this article, we critically assess evidence about putative effects of DBS on PIAAAS. We conducted a literature review of more than 1535 articles to investigate the prevalence of scientific evidence regarding these potential DBS-induced changes. While we observed an increase in the number of publications in theoretical neuroethics (...) that mention putative DBS-induced changes to patients’ postoperative PIAAAS, we found a critical lack of primary empirical studies corroborating these claims. Our findings strongly suggest that the theoretical neuroethics debate on putative effects of DBS relies on very limited empirical evidence and is, instead, reliant on unsubstantiated speculative assumptions probablyin lieuof robust evidence. As such, this may reflect the likelihood of a speculative neuroethics bubble that may need to be deflated. Nevertheless, despite the low number of first-hand primary studies and large number of marginal and single case reports, potential postoperative DBS changes experienced by patients remain a critical ethical concern. We recommend further empirical research in order to enhance theoretical neuroethics work in the area. In particular, we call for the development of better instruments capable of capturing potential postoperative variations of PIAAAS. (shrink)

Optogenetics is being optimistically presented in contemporary media for its unprecedented capacity to control cell behavior through the application of light to genetically modified target cells. As such, optogenetics holds obvious potential for application in a new generation of invasive medical devices by which to potentially provide treatment for neurological and psychiatric conditions such as Parkinson's disease, addiction, schizophrenia, autism and depression. Design of a first-in-human optogenetics experimental trial has already begun for the treatment of blindness. Optogenetics trials involve a (...) combination of highly invasive genetic and electronic interventions that results in irreversible and permanent modifications of an individual's nervous system. Given its novelty, its uncertain benefit to patients, and its unique risk profile of irreversible physiological alteration, optogenetics requires a reassessment of the ethical challenges for protecting human participants in clinical trials, particularly at formative stages of clinical evaluation. This study explores the evolving ethical issues surrounding optogenetics’ potential harm to participants within trial design, especially focusing on whether Phase 1 trials should incorporate efficacy as well as safety endpoints in ways that are fair and respectful to research trial participants.
