•Non-human primate (NHP) research needed to understand human brain and its diseases.•Neuroscience research in NHPs benefits from application of 3Rs.•UK neuroscientists using NHPs also actively engaged in using alternatives.•UK neuroscientists using NHPs also actively engaged in refining NHP research.•Application of 3Rs helps to ameliorate harms experienced in neuroscience procedures. This Feature focuses on UK neuroscience research using nonhuman primates (NHPs), and the application of the 3Rs, in the light of the recent EU SCHEER report and subsequent article by Prescott et al. (2017). The challenge of understanding the human brain and its disorders means that NHP research is still very much needed, although it is essential that this research is complemented by studies using other approaches, such as human volunteers and patients, and other alternatives to NHP use. Analysis of recent publications shows that these complementary approaches are already being actively exploited by NHP researchers in the UK. Application of the 3Rs has been led by the UK National Centre for the 3Rs (NC3Rs), with active participation of UK NHP researchers, who are constantly refining research methodology. However, not all refinements work, and those that do succeed need to be fully validated before they can be introduced more widely into current practice. More generally, the 3Rs have helped to ameliorate harm experienced by NHPs in procedures, although there is still more to do. Accumulating evidence from recent UK Home Office statistics suggests that most monkeys used in scientific procedures experience a moderate rather than a severe level of harm.
