MAASTRICHT. Neuroethics – all ethical questions concerning brain research – is a field of study that is becoming more and more important with all the technological and other developments. The more we know about the brain, the more we should think about what we are going to do with that information. What are the consequences for research, applications, patients, and humanity as a whole? That is what the NeuroEthics Symposium on 4 May is about, which is organised by students from the research master’s of Cognitive and Clinical Neuroscience.
