Deep brain stimulation (DBS) is a clinically established procedure for treating severe motor symptoms in patients suffering from end-stage Parkinson's disease, dystonia and essential tremor. Currently, it is tested for further indications including psychiatric disorders like major depression and a variety of other diseases. However, ethical issues of DBS(More)
Brain-Computer Interface (BCI) research and (future) applications raise important ethical issues that need to be addressed to promote societal acceptance and adequate policies. Here we report on a survey we conducted among 145 BCI researchers at the 4th International BCI conference, which took place in May-June 2010 in Asilomar, California. We assessed(More)
We are so surrounded by gadgetry that it is sometimes hard to tell where devices end and people begin. From computers and scanners to multifarious mobile devices, an increasing number of humans spend much of their conscious lives interacting with the world through electronics, the only barrier between brain and machine being the senses — sight, sound and(More)
PURPOSE OF REVIEW Progress in neurosciences, increasing computational power, and ongoing miniaturization of micro-technological components enable both a better understanding of human brain functions and development of new diagnostic and therapeutic tools. Research and development as well as clinical application of devices designed for recording neural(More)
Jens C. Clausen, David D. Keck, and William M. Hiesey’s biosystematic research on continental tarweeds (Madiinae; Compositae) provided diverse examples of evolutionary change for Clausen’s synthesis, Stages in the Evolution of Plant Species. Subsequent anatomical work by Sherwin Carlquist demonstrated that the tarweed lineage also includes a spectacular(More)
Harvesting human embryonic stem (hES) cells is a highly controversial field of research because it rests on the destruction of human embryos. Altering the procedure of nuclear transfer (NT) is suggested to generate hES cell lines without ethical obstacles by claiming that no embryo would be involved. While discussing the nature of an embryo and related(More)
r-nHE CARNEGIE INSTITUTION OF WASHINGTON is engaged in fundamental .1 research in the general fields of astronomy, the physical sciences, and the biological sciences. It was founded on January 28, 1902, by Andrew Carnegie and uses resources of over ninety million dollars "to encourage, in the broadest and most liberal manner, investigation , research, and(More)
Modern brain technology is a highly dynamic and innovative field of research with great potential for medical applications. Recent advances in recording neural signals from the brain by brain-machine interfacing presage new therapeutic options for paralyzed people by means of neural motor prostheses. This paper examines foreseeable ethical questions related(More)
One of the most controversial areas of animal research is the use of nonhuman primates for fundamental research. At the centre of the controversy is the question of whether the benefits of research outweigh the harms. We argue that the evaluation of harms and benefits is highly problematic. We describe some common procedures in neurological research using(More)
