A landmark in the scientific literature, the Oxford Handbook of Neuroethics presents a pioneering review of a topic central to the biosciences. It breaks new ground in bringing together leading neuroscientists, philosophers, and lawyers to tackle some of the most significant ethical issues that face us now and will continue to do so.

Cognitive‐enhancing drugs are prescribed to patients with psychiatric disorders, such as attention deficit hyperactivity disorder (ADHD) and Alzheimer's disease, to treat cognitive deficits. This chapter discusses the use of pharmacological agents to improve the cognition of both those with cognitive impairments and of the general population, as well as some of the benefits, risks, and ethical issues associated with the use of cognitive‐enhancing drugs. The chapter also talks about a survey run by the journal Nature, which was prompted by a (...) commentary by the authors of this chapter, that asked readers for their views on the issues surrounding cognitive enhancement. It can be seen that the ethical issues surrounding the use of cognitive‐enhancing drugs are complex and require discussion among different groups. With the development of new drugs and methods of enhancing cognition, such as brain stimulation, the need for further research and discussion is likely to become more pressing. (shrink)

How do our brains make choices? How do factors such as Alzheimer's or depression impair decision-making? Presenting the latest research on 'hot' and 'cold' decision-making, Barbara Sahakian and Jamie Nicole LaBuzetta look at the therapeutic smart drugs now available, and raise concerns about their unregulated use to enhance mental performance.

Several previous studies have reported atypicality in resting-state functional connectivity in autism spectrum disorder, yet the relatively small effect sizes prevent us from using these characteristics for diagnostic purposes. Here, canonical correlation analysis and hierarchical clustering were used to partition the high-functioning ASD group into subgroups. A support vector machine model was trained through the 10-fold strategy to predict Autism Diagnostic Observation Schedule scores within the ASD discovery group, which was further validated in an independent sample. The neuroimage-based partition derived (...) two subgroups representing severe versus mild autistic patients. We identified FCs that show graded changes in strength from ASD-severe, through ASD-mild, to controls, while the same pattern cannot be observed in partitions based on ADOS score. We also identified FCs that are specific for ASD-mild, similar to a partition based on ADOS score. The current study provided multiple pieces of evidence with replication to show that resting-state functional magnetic resonance imaging FCs could serve as neural biomarkers in partitioning high-functioning autistic individuals based on their symptom severity and showing advantages over traditional partition based on ADOS score. Our results also indicate a compensatory role for a frontocortical network in patients with mild ASD, indicating potential targets for future clinical treatments. (shrink)

The new field of neuroethics has recently emerged following unprecedented developments in the neurosciences. Neuroimaging and cognitive enhancement in particular are demanding ethical debate. For example, neuroscientists are able to measure, with increasing accuracy, intimate personal biases and thoughts as they occur in the brain. Smart drugs are now available that can effectively and safely enhance mental functioning in both healthy and clinical populations. This article describes the scientific principles behind these technologies, and urges the development of ethical principles based (...) on a clear understanding of them. Europe should take the United States’ lead in devoting resources specifically intended to examine neuroethical concerns within European healthcare and legal frameworks. (shrink)
