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.

Der Beitrag arbeitet ein Problem der psychotherapeutischen Praxis – den Konflikt zwischen konfrontativer Traumatherapie und Strafverfahren – und das daraus resultierende traumatherapeutische Dilemma unter rechtlichen und therapeutischen Gesichtspunkten auf und skizziert einen Vorschlag, wie es in vielen Fällen gelindert werden kann. Das Dilemma erwächst aus dem Umstand, dass Traumatherapie die Glaubhaftigkeit von Zeugenaussagen unterminiert, da es ihre Bestätigung durch die Aussageanalyse aus methodischen Gründen verunmöglicht. Zur Umgehung dieses Problems wird vorgeschlagen, die traumatherapeutischen Behandlungsmethoden so weiterzuentwickeln, dass sie es ermöglichen, Aussagen (...) von Patienten innerhalb der Therapie, aber außerhalb der Justiz zu dokumentieren. Im besten Fall ist dies als Vorstufe zu konfrontativen Therapieabschnitten in die Manuale einzubetten. Als Form wird die Entwicklung einer die Aussage strukturierenden Software vorgeschlagen. Zudem sollten Patienten über nachteilige Auswirkungen von Traumatherapien auf Glaubhaftigkeitsbegutachtungen aufgeklärt werden. Im Zusammenspiel mit in Gesetz und Judikatur bereits angelegten, aber praktisch nicht immer wirksamen Verbesserungen für traumatisierte Zeugen ließe sich die Situation Betroffener in vielen Fällen spürbar verbessern.

Discussion of the ethics of memory modification technologies has often focused on questions about the limits of their permissibility. In the current paper, I focus primarily on a different issue: when is it rational to prefer MMTs to alternative interventions? My conclusion is that these conditions are rare. The reason stems from considerations of autonomy. When compared with other interventions, MMTs do a particularly poor job at promoting the autonomy of their users. If this conclusion is true, moreover, it provides (...) a fresh perspective on debates about the permissibility of MMTs. On the one hand, for those who would limit the use of MMTs to a narrow range of circumstances, the conclusion that MMTs are rarely preferable gives them further reason to eye MMTs with suspicion. On the other hand, for those who view MMTs as permissible in a wide range of circumstances, the conclusion may deflate their endorsement. (shrink)

It is a mistake to think that we cannot be morally responsible for forgetting because, as a matter of principle, forgetting is outside of our control. Sometimes we do have control over our forgetting. When forgetting is under our control there is no question that it is the proper object of praise and blame. But we can also be morally responsible for forgetting something when it is beyond our control that we forget that thing. The literature contains three accounts of (...) the blameworthiness of forgetting over which the agent has no control—the tracing account, the liberalized awareness condition, and attributionism. Even though these are competing accounts of the blameworthiness of harmful forgetting they are compatible with one another. In particular, it is possible to come up with a position that endorses the tracing account for certain kinds of harmful forgetting and attributionism for other kinds of harmful forgetting. (shrink)

Post-traumatic stress disorder is a “young” disorder formally recognized in the early 1980s, although the symptoms have been noted for centuries particularly in relation to military conflicts. PTSD may develop after a serious traumatic experience that induces feelings of intense fear, helplessness or horror. It is currently characterized by three key classes of symptoms which must cause clinically significant distress or impairment of functioning: persistent and distressing re-experiencing of the trauma; persistent avoidance of stimuli associated with the trauma and numbing (...) of general responsiveness; and persistent symptoms of hyper-arousal. One of the possible symptoms within the second class is difficulty in remembering an important aspect of the traumatic event.PTSD is not an uncommon condition, with an estimated lifetime prevalence of about 7-9% based on studies conducted in the United States and Canada, with women at higher risk than men. While not everyone who experiences a significant trauma will go on to develop PTSD, about a third will do so. Sexual assault, along with other forms of assaultive violence, pose a comparatively high risk of PTSD. (shrink)

The neurosciences not only challenge assumptions about the mind’s place in the natural world but also urge us to reconsider its role in the normative world. Based on mind-brain dualism, the law affords only one-sided protection: it systematically protects bodies and brains, but only fragmentarily minds and mental states. The fundamental question, in what ways people may legitimately change mental states of others, is largely unexplored in legal thinking. With novel technologies to both intervene into minds and detect mental activity, (...) the law should, we suggest, introduce stand alone protection for the inner sphere of persons. We shall address some metaphysical questions concerning physical and mental harm and demonstrate gaps in current doctrines, especially in regard to manipulative interferences with decision-making processes. We then outline some reasons for the law to recognize a human right to mental liberty and propose elements of a novel criminal offence proscribing severe interventions into other minds. (shrink)

(draft) In this chapter, I examine the most significant ethical questions surrounding memory, both at the collective and individual levels, as discussed in the literature. I begin by exploring the values associated with memory, including truth, accuracy, integrity, and broader social and political dimensions. I then address the concept of a duty to remember, particularly in the context of genocide and other human atrocities, and the complex questions this concept raises. Following this, I analyze the ethical challenges posed by forgetting, (...) focusing on its collective implications for forgiveness and its individual dimensions, such as the responsibility for forgetting and the right to be forgotten. After briefly discussing memory virtues—a topic that remains underexplored in the literature—I explore the ethical considerations surrounding the wishes of individuals with severe memory loss, such as those with dementia. Finally, I summarize ethical debates related to current and hypothetical cases of memory modification, erasure, and enhancement, highlighting their potential impacts on personal identity, agency, authenticity, moral responsibility, testimony, and their overall desirability.

Memory blunting is a pharmacological intervention that decreases the emotional salience of memories. The technique promises a brighter future for those suffering from memory-related disorders such as PTSD, but it also raises normative questions about the limits of its permissibility. So far, neuroethicists have staked out two primary camps in response to these questions. In this paper, I argue both are problematic. I then argue for an alternative approach to memory blunting, one that can accommodate the considerations that motivate rival (...) approaches even while avoiding the problems these rivals face. In addition to arguing for this primary thesis, the paper also aims to suggest something about neuroethics generally: despite what some neuroethicists claim, new discoveries in neuroscience may not typically upend traditional views of morality. Rather, discoveries in neuroscience often provide us with new occasions to reflect on enduring questions about what it means to be human. (shrink)

Since Freud, clinicians have understood that disturbing memories contribute to psychopathology and that new emotional experiences contribute to therapeutic change. Yet, controversy remains about what is truly essential to bring about psychotherapeutic change. Mounting evidence from empirical studies suggests that emotional arousal is a key ingredient in therapeutic change in many modalities. In addition, memory seems to play an important role but there is a lack of consensus on the role of understanding what happened in the past in bringing about (...) therapeutic change. The core idea of this paper is that therapeutic change in a variety of modalities, including behavioral therapy, cognitive-behavioral therapy, emotion-focused therapy, and psychodynamic psychotherapy, results from the updating of prior emotional memories through a process of reconsolidation that incorporates new emotional experiences. We present an integrated memory model with three interactive components – autobiographical (event) memories, semantic structures, and emotional responses – supported by emerging evidence from cognitive neuroscience on implicit and explicit emotion, implicit and explicit memory, emotion-memory interactions, memory reconsolidation, and the relationship between autobiographical and semantic memory. We propose that the essential ingredients of therapeutic change include: (1) reactivating old memories; (2) engaging in new emotional experiences that are incorporated into these reactivated memories via the process of reconsolidation; and (3) reinforcing the integrated memory structure by practicing a new way of behaving and experiencing the world in a variety of contexts. The implications of this new, neurobiologically grounded synthesis for research, clinical practice, and teaching are discussed. (shrink)

One of the ethical issues that has been raised recently regarding emerging neurotherapies is that people will be coerced explicitly or implicitly in the workplace or in schools to take cognitive enhancing drugs. This article builds on this discussion by showing how the law may pressure people to adopt emerging neurotherapies. It focuses on a range of private law doctrines that, unlike the criminal law, do not come up very often in neuroethical discussions. Three doctrines—the doctrine of mitigation, the standard (...) of care in negligence, and child custody determinations in family law—are addressed to show how the law may pressure people to consent to treatment by offering a choice between accepting medical treatment and suffering a legal disadvantage. The doctrines considered in this article apply indirect pressure to submit to treatment, unlike court-ordered medical treatment, which applies direct pressure and is not addressed here. The outcome of this discussion is to show that there is a greater range of social pressures that may encourage the uptake of novel neurotherapies than one might initially think. Once treatments that were developed and offered with therapeutic benefits in mind become available, their existence gives rise to unintended legal consequences. This certainly does not mean we should cease developing new therapies that may be of tremendous benefit to patients, but it does raise some questions for physicians and for legal policy-makers. How should physicians, who are required by medical ethical principles to obtain valid consent to treatment, react to a patient’s reluctant consent that is driven by legal pressure? From the legal policy perspective, are our legal doctrines satisfactory or should they be changed because, for example, they unduly promote the collective interest over individual freedom to reject medical treatment or because they channel us toward economically efficient treatments to the detriment of more costly but potentially superior approaches of dealing with behavioural problems?

This study deals specifically with one of the most relevant issues in neuro-ethics, namely the philosophical classification of so-called memory dampening, which refers to the attenuation of traumatic memories with the help of medication. Numerous neuroethical questions emerge from this issue. For example, how is a person’s identity affected by using such drugs? Does one still remain the same person? Would propranolol, for example, as a memory-dampening agent lead to a fundamental change in one’s identity? Are not a person’s negative (...) memories also part of their identity and present personality? These questions are examined from the perspective of the seventeenth-century Islamic philosopher, Mullā Ṣadrā. The goal is to shed light on the neuroethical foundations of memory dampening and personal identity from an Islamic philosophical perspective. (shrink)

Neuroscientific research on the removal of unpleasant and traumatic memories is still at a very early stage, but is making rapid progress and has stirred a significant philosophical and neuroethical debate. Even if memory is considered to be a fundamental element of personal identity, in the context of memory-erasing the autonomy of decision-making seems prevailing. However, there seem to be situations where the overall context in which people might choose to intervene on their memories would lead to view those actions (...) as counterproductive. In this article, I outline situations where the so-called composition effects can produce negative results for everyone involved, even if the individual decisions are not as such negative. In such situations medical treatments that usually everyone should be free to take, following the principle of autonomy, can make it so that the personal autonomy of the individuals in the group considered is damaged or even destroyed. In these specific cases, in which what is called the “conformity to context” prevails, the moral admissibility of procedures of memory-erasing is called into question and the principle of personal autonomy turns out to be subordinate to social interests benefitting every member of the group.

The National Institute of Mental Health reports that approximately 5.2 million Americans experience post-traumatic stress disorder each year. PTSD can be severely debilitating and diminish quality of life for patients and those who care for them. Studies have indicated that propranolol, a beta-blocker, reduces consolidation of emotional memory. When administered immediately after a psychic trauma, it is efficacious as a prophylactic for PTSD. Use of such memory-altering drugs raises important ethical concerns, including some futuristic dystopias put forth by the President's (...) Council on Bioethics. We think that adequate informed consent should facilitate ethical research using propranolol and, if it proves efficacious, routine treatment. Clinical evidence from studies should certainly continue to evaluate realistic concerns about possible ill effects of diminishing memory. If memory-attenuating drugs prove effective, we believe that the most immediate social concern is the over-medicalization of bad memories, and its subsequent exploitation by the pharmaceutical industry.

Emerging technologies raise the possibility that we may be able to treat trauma victims by pharmaceutically dampening factual or emotional aspects of their memories. Such technologies raise a panoply of legal and ethical issues. While many of these issues remain off in the distance, some have already arisen. In this brief commentary, I discuss a real-life case of memory erasure. The case reveals why the contours of our freedom of memory—our limited bundle of rights to control our memories and be (...) free of outside control—already merit some attention. (shrink)

Die Posttraumatische Belastungsstörung (PTBS) ist ein schwerwiegendes psychisches Krankheitsbild, das Betroffene nach dem Erleben traumatisierender Situationen entwickeln. Im Zusammenhang mit den Auslandseinsätzen der Bundeswehr ist die PTBS bei Soldaten in den letzten Jahren verstärkt in den Fokus der deutschen Öffentlichkeit gerückt. Auch zivile Traumata bergen ein großes PTBS-Risiko. Seit einigen Jahren werden Methoden zur medikamentösen Prävention der PTBS erforscht. Die beiden wichtigsten Ansätze, die Prävention mit zentralnervös wirkenden Betablockern und Glukokortikoiden, basieren auf der Idee, durch den Eingriff in neuroendokrine Stressachsen (...) Einfluss auf die Art und Weise zu nehmen, in der die Erinnerung im Gedächtnis konsolidiert wird. Durch eine Entemotionalisierung und Abschwächung entsprechender Gedächtnisspuren soll das spätere Auftreten einer PTBS verhindert werden. Beide Ansätze zeigen in Pilotstudien vielversprechende Ergebnisse. Angesichts der herausragenden Bedeutung des Gedächtnisses für Individuum und Gesellschaft sollten Ansätze zur medikamentösen Gedächtnismodifikation (MGM) unter neuroethischen Gesichtspunkten diskutiert und bewertet werden. Der Text beleuchtet die MGM zur PTBS-Prävention entlang von fünf Problemachsen: 1) der Einflussnahme von MGM auf den Prozess der normalen psychischen Verarbeitung traumatischer Erlebnisse, 2) der Gefahr einer Entkopplung von Erinnerung und Realität, 3) der Bedeutung von emotionaler Erinnerung für die Moral, 4) der sozialen, juristischen und historischen Relevanz einer wahrhaftigen Erinnerungskultur und 5) der potenziellen Förderung eines gesellschaftlichen Medikalisierungsprozesses. Trotz ernsthaft zu diskutierender ethischer Bedenken ist – vor dem Hintergrund der Schwere des Krankheitsbilds – aus unserer Sicht eine MGM zur PTBS-Prävention grundsätzlich begrüßenswert, sollte jedoch derzeit nur im Rahmen klinischer Studien erfolgen. Hierfür stellen wir acht forschungsethische Aspekte zur Diskussion, die bei solchen Studien zu berücksichtigen sind. (shrink)

In recent years, discussion around memory modification interventions has gained attention. However, discussion around the use of memory interventions in the criminal justice system has been mostly absent. In this paper we start by highlighting the importance memory has for human well-being and personal identity, as well as its role within the criminal forensic setting; in particular, for claiming and accepting legal responsibility, for moral learning, and for retribution. We provide examples of memory interventions that are currently available for medical (...) purposes, but that in the future could be used in the forensic setting to modify criminal offenders’ memories. In this section we contrast the cases of dampening and enhancing memories of criminal offenders. We then present from a pragmatic approach some pressing ethical issues associated with these types of memory interventions. The paper ends up highlighting how these pragmatic considerations can help establish ethically justified criteria regarding the possibility of interventions aimed at modifying criminal offenders’ memories.

Funding: Research funded by Canadian Institutes of Health Research, NNF 80045, States of Mind: Emerging Issues in Neuroethics. While there are those who object to the prospective use of propranolol to prevent or treat post-traumatic stress disorder (PTSD), most obstreperous among them the President’s Council on Bioethics, the use of propranolol can be justified for patients with severe PTSD. Propranolol, if effective, will alter the quality of certain memories in the brain. But this is not a serious threat to the (...) self understood in terms of narrative identity. A narrative identity framework acknowledges that memory is always being subtly altered or modified. For severe cases of PTSD propranolol may help victims who don’t respond to any other therapy or therapy combination regain their authentic self-narrative and engage once more in life activities. For those whose symptoms are not so severe the potential risks and side-effects of the drug may outweigh the benefits. Patients and family members should be allowed to decide, in consultation with their physician, whether this drug is appropriate in their case. (shrink)

Memory modification technology (MMT) refers to the use of neurotechnologies to intervene in memories. Many scholars have reflected on the ethical issues in MMT, but a comprehensive review of this topic has not been seen. This article presents the first scoping review study of ethical issues in MMT using a bibliometric and systematic approach. After thorough examination, 133 records of key literature are included in this scoping review. Six core ethical themes are extracted: (1) self, identity, and authenticity; (2) autonomy (...) and informed consent; (3) welfare and happiness; (4) safety and risks; (5) responsibility and obligation; (6) social and legal justice. More detailed analyses are conducted on the moral stances and reasons held by different scholars concerning these ethical themes. As can be seen, current debates exhibit certain shortcomings, including ambiguous ethical concepts and a restricted scope of analysis. Therefore, we call for deeper reflections on the philosophical foundations, more precise definitions of ethical terms, and more comprehensive examinations of neurotechnological applications, in order to better address the ethical challenges in the future.

The debate over the propriety of cognitive enhancement evokes both enthusiasm and worry. To gain further insight into the reasons that people may have for endorsing or eschewing pharmacological enhancement, we used empirical tools to explore public attitudes towards PE of twelve cognitive, affective, and social domains. Participants from Canada and the United States were recruited using Mechanical Turk and were randomly assigned to read one vignette that described an individual who uses a pill to enhance a single domain. After (...) reading the vignette, participants were asked how comfortable they were with the individual using the enhancement. People were significantly more comfortable when they read about enhancement of certain CAS domains than others. We found a modest negative correlation between comfort level and the degree to which the PE was perceived as changing core features of the person. We also found a modest correlation between comfort level and the degree to which the PE was perceived as improving success in life. Finally, using a sequential mixed method technique, we found that participants who felt uncomfortable about PE use overwhelmingly focused on a lack of need and, to a lesser degree, expressed concerns about safety; those who felt comfortable about PE use most frequently mentioned the safety of the pill and its ability to provide a positive outcome. The data provide novel insights into public enthusiasms and concerns over the use of PE. (shrink)

We like to think we own our memories: if technology someday enables us to alter our memories, we should have certain rights to do so. But our freedom of memory has limits. Some memories are simply too valuable to society to allow individuals the unfettered right to change them. Suppose a patient regains consciousness in the middle of surgery. While traumatized by the experience and incapable of speaking, he coincidentally overhears two surgeons make plans to set fire to the hospital. (...) Assuming there is no way to erase his traumatic memories of intraoperative awareness and still prosecute the surgeons, a patient may well have a moral duty to retain the memories for the greater good. And if the patient has such a moral duty, I argue in this brief comment, then the state plausibly has the right to limit our abilities to erase memories when necessary to protect public safety or prosecute offenders.

The neural basis of human memory is incredibly complex. We argue that the diversity of neural systems underlying various forms of memory suggests that any discussion of enhancing ‘memory’ per se is too broad, thus obfuscating the biopolitical debate about human enhancement. Memory can be differentiated into at least four major systems with largely dissociable neural substrates. We outline each system, and discuss both the practical and the ethical implications of these diverse neural substrates. In practice, distinct neural bases imply (...) the possibility, and likely the necessity, of specific approaches for the safe and effective enhancement of various memory systems. In the debate over the ethical and social implications of enhancement technologies, this fine-grained perspective clarifies—and may partially mitigate—certain common concerns in enhancement debates, including issues related to safety, fairness, coercion, and authenticity. While many researchers certainly appreciate the neurobiological complexity of memory, the political debate tends to revolve around a monolithic one-size-fits-all conception. The overall project—exploring how human enhancement technologies affect society – stands to benefit from a deeper appreciation of memory’s neurobiological diversity. (shrink)

In this chapter, I propose the mechanism of cognitive enhancement based on studies of cognitive-enhancing drugs and behavioral training. I argue that there are mechanistic differences between cognitive-enhancing drugs and behavioral training due to their different enhancing effects. I also suggest possible mechanisms for cognitive-enhancing drugs and behavioral training and for the synergistic effects of their simultaneous application.

The United States has been waging the “War on Terror” for nearly two decades. Obscured among the more obvious costs of that war is the moral injury borne by many of the soldiers who have fought and participated in it. Unlike post-traumatic stress disorder, which is rooted in fear, moral injury is rooted in shame, shame for having committed a moral transgression, a violation of the moral code. Haunted by the memory of their misdeeds, these soldiers are plagued by all (...) manner of illness and infirmity, from anxiety and depression to substance abuse and suicide. In this article, I explore whether these soldiers have a right to forget, one that would entitle them to use pharmacological or psychological manipulation to cleanse their minds of the memory that they have dirtied their hands, and in that way relieve themselves of the anguish and torment from which they suffer.
