Reproducibility of results is one of the keystones in science and, in fact, is what makes science advanced over the centuries. The search for high reproducibility of the same experimental protocol across different sessions is particularly critical for longitudinal studies in functional neuroscience and in different clinical applications so that one can disentangle the variability caused by systematic errors due to instrumentation/protocol from the intrinsic variability due to the research question. Specifically for fNIRS studies, we have found several contributors to systematic errors over the past ten years, such as motion artifacts, extra cortical contamination, and global systemic physiology. More recently, we have found that the lack of spatial information of the optodes on the head can also introduce a major confounding source to the results and lead to misinterpretation of data. In this talk, we will discuss the major problems that contribute to systematic errors in fNIRS, and present recent solutions we implemented to reduce variability in fNIRS protocols - including the integration of a real-time neuronavigator system to guide probe placement of optodes in fNIRS.
