Quality control and assurance in functional near infrared spectroscopy (fNIRS) experimentation [PDF]

Physics in Medicine and Biology, 2010
Functional near infrared spectroscopy (fNIRS) is a rapidly developing neuroimaging modality for exploring cortical brain behaviour. Despite recent advances, the quality of fNIRS experimentation may be compromised in several ways: firstly, by altering the optical properties of the tissues encountered in the path of light; secondly, through adulteration ...

Measurement of Brain Function of Car Driver Using Functional Near‐Infrared Spectroscopy (fNIRS) [PDF]

Computational Intelligence and Neuroscience, 2009
The aim of this study is to propose a method for analyzing measured signal obtained from functional Near‐Infrared Spectroscopy (fNIRS), which is applicable for neuroimaging studies for car drivers. We developed a signal processing method by multiresolution analysis (MRA) based on discrete wavelet transform.
