Over its short history, the young field of “neuroethics” has enjoyed remarkable public support within neuroscience. For instance, since 2006 the Annual Meeting of the Society for Neuroscience has h...

Brain-Computer Interface is a set of technologies that are of increasing interest to researchers. BCI has been proposed as assistive technology for individuals who are non-communicative or paralyzed, such as those with amyotrophic lateral sclerosis or spinal cord injury. The technology has also been suggested for enhancement and entertainment uses, and there are companies currently marketing BCI devices for those purposes as well as health-related purposes. The unprecedented direct connection created by BCI between human brains and computer hardware raises various (...) ethical, social, and legal challenges that merit further examination and discussion. To identify and characterize the key issues associated with BCI use, we performed a scoping review of biomedical ethics literature, analyzing the ethics concerns cited across multiple disciplines, including philosophy and medicine. Based on this investigation, we report that BCI research and its potential translation to therapeutic intervention generate significant ethical, legal, and social concerns, notably with regards to personhood, stigma, autonomy, privacy, research ethics, safety, responsibility, and justice. Our review of the literature determined, furthermore, that while these issues have been enumerated extensively, few concrete recommendations have been expressed. We conclude that future research should focus on remedying a lack of practical solutions to the ethical challenges of BCI, alongside the collection of empirical data on the perspectives of the public, BCI users, and BCI researchers.

Medical interventions are usually categorized as “invasive” when they involve piercing the skin or inserting an object into the body. Beyond this standard definition, however, there is little discussion of the concept of invasiveness in the medical literature, despite evidence that the term is used in ways that do not reflect the standard definition of medical invasiveness. We interviewed psychiatrists, patients with depression, and members of the public without depression to better understand their views on the invasiveness of several psychiatric (...) electroceutical interventions (treatments that involve electrical or magnetic stimulation of the brain) for the treatment of depression. Our study shows that people recognize several kinds of invasiveness: physical, emotional, and lifestyle. In addition, several characteristics of therapies influence how invasive they are perceived to be; these include the perceived capacity of an intervention to result in harm; how localized the effects of the intervention are; the amount of control retained by the person receiving the intervention; how permanent its effects are perceived as being; and how familiar it seemed to participants. Our findings contribute to a small literature on the concept of invasiveness, which emphasizes that categorizing an intervention as invasive, or as noninvasive, evokes a variety of other normative considerations, including the potential harm it poses and how it compares to other potential therapies. It may also draw attention away from other salient features of the intervention. (shrink)

As early-career neuroethicists, we come to the field of neuroethics at a unique moment: we are well-situated to consider nearly two decades of neuroethics scholarship and identify challenges that have persisted across time. But we are also looking squarely ahead, embarking on the next generation of exciting and productive neuroethics scholarship. In this article, we both reflect backwards and turn our gaze forward. First, we highlight criticisms of neuroethics, both from scholars within the field and outside it, that have focused (...) on speculation and lack of skepticism; the dearth of consideration of broader social issues such as justice and equality, both with regard to who speaks for neuroethics as a field and who benefits from its recommendations and findings; and the insufficient focus on the practical impact of our ethical work. Second, we embrace the concept of “translational neuroethics” to outline a vision for neuroethics that is integrated, inclusive, and impactful. Integration can help us identify more pertinent, real-world issues, and move away from speculation; inclusivity can help ensure that the questions we attend to are not merely relevant to a single subgroup but aim toward just distribution of benefits; and impact can help us think beyond guidelines and recommendations to focus on implementation. Our goal is for this call to action to help shape neuroethics into a discipline that develops rigorous research agendas through relationships with interdisciplinary partners, that is broadly inclusive and attends to issues beyond novel neurotechnologies, and that is devoted to the translation of scholarship into practice.

Invasive neural devices offer novel prospects for motor rehabilitation on different levels of agentive behavior. From a functional perspective, they interact with, support, or enable human intentional actions in such a way that movement capabilities are regained. However, when there is a technical malfunction resulting in an unintended movement, the complexity of the relationship between the end user and the device sometimes makes it difficult to determine who is responsible for the outcome – a circumstance that has been coined as (...) “responsibility gap” in the literature. So far, recent accounts frame this issue around the theme of control but more work is needed to explore the complicated terrain of assigning responsibility for neural device-mediated actions from this control perspective. This paper aims at contributing to this tendency by offering more fine-grained distinctions of how that control capacity is facilitated by the machine and how it can be exercised by the end user. This results in a novel framework that depicts an in-depth exploration of the control aspect of responsibility in a way that incorporates the diversity of relationships between neurotechnologies, the various conditions they treat, and the individual end user’s experience.

The relation between the notions of (medical) invasiveness and (actual or potential) harm has not been systematically discussed nor theoretically grounded, despite its importance to clinical-ethical practice. This paper aims to clarify the notion of invasiveness beyond the traditional notion of invasiveness as breaking skin or inserting mechanical objects into the body. The traditional notion of invasiveness is challenged by counterexamples. Three approaches to the notion of disorder applied here are: deviation from what is common; deviation from what is considered (...) ideal; and disruption of self-organization. Assuming that more extreme measures are related to more harm, all three approaches to the notion of disorder suggest that invasiveness is proportional if not identical to harm, and show no clear relation to the traditional notion of invasiveness. In conclusion, the notion of invasiveness may best be eliminated from medical terminology, replacing it with a detailed understanding of the notion of harm. (shrink)

We have long used mechanical devices to compensate for physical disability. Soon, however, it may be possible to augment mental capacity—to add memory or upgrade processing power. We should ponder the enormous moral implications of the machine‐assisted mind now, before it is accomplished.

Deep brain stimulation (DBS) of the globus pallidus interna and subthalamic nucleus has restored some degree of motor control in many patients in advanced stages of Parkinson’s disease. DBS has also been used to treat dystonia, essential tremor (progressive neurological condition causing trembling), chronic pain, obsessive-compulsive disorder, Tourette’s syndrome, major depressive disorder, obesity, cerebral palsy, and the minimally conscious state. Although the underlying mechanisms of the technique are still not clear, DBS can modulate underactive or overactive neural circuits and restore (...) disrupted communication between and among groups of neurons in interacting regions of the brain. This can control and relieve many symptoms associated with a range of neurological and psychiatric disorders.But the procedures of implanting and stimulating the electrodes are brain-invasive and entail significant risks. Some patients receiving DBS have experienced intracerebral hemorrhage, infection, cognitive disturbances such as impulsive behavior, and affective disturbances such as mania. It is not known whether continuous electrical stimulation of the brain would reshape synaptic connectivity and permanently alter neural circuits in ways that may not be salutary. The risk of these effects indicates that DBS should be used only when a patient’s condition is refractory to all other interventions and when there is a high probability that the technique will benefit the patient and improve his or her quality of life. If a patient’s quality of life is poor and all other treatment options have been exhausted, then the likelihood of benefit can justify physicians’ exposing patients to some risk. The clinical and ethical significance of the risk in DBS underscores the obligation of physicians to obtain fully informed consent from patients undergoing the procedure. (shrink)

There is mounting evidence that non-invasive brain stimulation devices - transcranial direct current stimulation and transcranial magnetic stimulation could be used for cognitive enhancement. However, the regulatory environment surrounding such uses of stimulation devices is less clear than for stimulant drugs—a fact that has already been commercially exploited by several companies. In this paper, the mechanism of action, uses and adverse effects of non-invasive neurostimulation devices are reviewed, along with social and ethical challenges pertaining to their use as cognitive enhancements. (...) Two regulatory approaches that could be used to facilitate responsible use of these devices as products and services are outlined. Apart from establishing the urgently needed comprehensive regulatory framework, they might provide a starting point for establishing long term physiological and social effects of enhancement uses of tDCS and TMS.
