In the following text, medical, anthropological and ethical issues of deep brain stimulation, a medical technology in which electrodes implanted in the human brain electrically influence specified brain regions, will be discussed. After a brief account of the deep brain stimulation procedure and its chances and risks, anthropological and ethical aspects of the approach will be discussed. These relate to the reversibility of the procedure and to the patient’s capacity to control the effects it exerts in the brain, to modifications and fluctuations in a person’s character traits and individuality brought about by neurostimulation, and to the range of legitimate, adequate uses of the deep brain stimulation approach. The paper concludes that deep brain stimulation should be confined to therapeutic contexts and to severe, otherwise treatment-refractory disorders in which the aim is to normalize brain functioning. Apart from this, it should not be used to modify a person’s individual character traits and behaviour or to enhance human traits

In this paper, the results of a pilot interview study with 19 subjects participating in an EEG-based non-invasive brain–computer interface (BCI) research study on stroke rehabilitation and assistive technology and of a survey among 17 BCI professionals are presented and discussed in the light of ethical, legal, and social issues in research with human subjects. Most of the users were content with study participation and felt well informed. Negative aspects reported include the long and cumbersome preparation procedure, discomfort with the cap and the wet electrodes, problems concerning BCI control, and strains during the training sessions. In addition, some users reflected on issues concerning system security. When asked for morally problematic issues in this field of non-invasive BCI research, the BCI professionals stressed the need for correct information transfer, the obligation to avoid unrealistic expectations in study participants, the selection of study participants, benefits and strains of participation, BCI illiteracy, the possibility of detrimental brain modifications induced by BCI use, and problems that may arise at the end of the trials. Furthermore, privacy issues were raised. Based on the results obtained, psychosocial and ethical aspects of EEG-based non-invasive BCI research are discussed and possible implications for future research addressed

Academic performance enhancement or cognitive enhancement (CE) via stimulant drug use has received increasing attention. The question remains, however, whether CE solely represents the use of drugs for achieving better academic or workplace results or whether CE also serves various other purposes. The aim of this study was to put the phenomenon of pharmacological academic performance enhancement via prescription and illicit (psycho-) stimulant use (Amphetamines, Methylphenidate) among university students into a broader context. Specifically, we wanted to further understand students’ experiences, the effects of use on students and other factors, such as pressure to perform in their academic and private lives
