With these motivations as a driving force, the research into NIR based brain activity monitoring have blossomed in the past 20 years with growing number of potential applications. So far, brain activity monitoring has seen applications in physiological studies of brain disfunction, preterm neonatal care, education and training, and cognitive workload assessment. [Pg.342]

In this review, it is our goal to give an overview of the breadth of research conducted in the past 20 years. As with most review of this nature, we cover the breadth and do not intend to provide close in depth [Pg.342]

In order to better quantify the absolute value of chromophore concentrations, time of flight (TOF) must be measured in addition to light attenuation. This may be achieved using time-resolved or frequency domain methods. Time-resolved spectroscopy (TRS) was first pioneered by Delpy et. al. [19], Patterson et. al. [85] and Chance et al. [12, 13].
