Abstract

Ideally, measurements of brain function should be performed non-invasively and in environments that do not remove the task's context. For example, if we are interested in investigating a football player's brain, ideally, we should measure the brain during a match, thus providing ecological validity. In neuroscience, advances in instrumentation, computational power and signal processing methods have allowed for novel tools to investigate brain activity in real-time and everyday environments. In this context, techniques such as fMRI and PET are not ideal since they require expensive and extensive instrumentation. On the other hand, techniques such as NIRS and EEG provide portable, accessible ways of measuring brain function. To achieve this, a series of multidisciplinary challenges need to be addressed. In addition, neurophysiological signals have to be measured in a stable, safe and robust manner while not restraining the subject. To this end, this dissertation describes the design and development of technology for NIRS measurements in natural environments and provides a roadmap for the continuation of this work (AU)
