Acute moderate exercise elicits increased dorsolateral prefrontal activation and improves cognitive performance with Stroop test (2010, methodology): “As a promising neuroimaging technique for investigating the acute effects of exercise on cognition, we introduced functional near-infrared spectroscopy (fNIRS): an optical method that non-invasively monitors cerebral hemodynamics by measuring changes in the attenuation of nearinfrared light passing ”
Neuroimaging: Decoding mental states from brain activity in humans (2006, neutral): “Of current technologies, only the recording of electrical or optical signals with EEG or near infrared spectroscop”
A Wearable Multi-Channel fNIRS System for Brain Imaging in Freely Moving Subjects (2013, background): “It has been promoted for its i) non-invasive, non-ionizing nature, ii) bed-side applicability (Obrig and Villringer, 2003; Steinkellner et al., 2010; Tobias, 2006; Toet and Lemmers, 2009), iii) relatively low costs, iv) ease of integration with other modalities such as electro encephalography (EEG)…”
The modified Beer–Lambert law revisited (2006, methodology): “The water content of the cortex is approximately 80%, the total haemoglobin concentration is about 90 µM and the average saturation is about 70% (Torricelli et al 2001, Obrig and Villringer 2003), i.e. Cwater = 0.80, cHb,0 = 27 µM, cHbO2,0 = 63 µM.”
NIRS-SPM: statistical parametric mapping for near infrared spectroscopy (2008, neutral): “However, these approaches also rely on time-line analysis approaches (Obrig and Villringer, 2003) for which specific differential path length factors (DPF) should be assumed.”
Optical brain monitoring for operator training and mental workload assessment (2012, neutral): “Scattering is high within the tissue but is generally assumed to be constant throughout the measurement (Obrig and Villringer, 2003).”
Illuminating the developing brain: the past, present and future of functional near infrared spectroscopy. (2010, background): “In adults, typically the increase in CBF exceeds the demand for oxygen (Obrig and Villringer, 2003; Raichle, 1998) leading to an fNIRS measured haemodynamic response as shown in Fig.”
Event-related functional near-infrared spectroscopy (fNIRS): Are the measurements reliable? (2006, methodology): “Like functional magnetic resonance imaging (fMRI), functional near-infrared spectroscopy (fNIRS) is a haemodynamic-based technique for the assessment of functional activity in the human brain (e.g. Hoshi, 2003; Obrig and Villringer, 2003; Villringer and Chance, 1997).”
A review on continuous wave functional near-infrared spectroscopy and imaging instrumentation and methodology (2014, background): “As mentioned above, this approximation does not hold true for measurements of the head, as discussed by e.g. (Boas et al., 2001; Obrig and Villringer, 2003).”
A brief review on the history of human functional near-infrared spectroscopy (fNIRS) development and fields of application (2012, neutral): “In 1999, the Humboldt University of Berlin built a 22-channel CW instrument that was utilized successfully for human visual cortex studies (Obrig and Villringer, 2003).”
Wavelet-based motion artifact removal for functional near-infrared spectroscopy (2012, background): “Functional studies in infants have many applications in areas such as brain development in infants (Obrig and Villringer 2003), speech perception (Gervain et al 2008), premature infant studies (Hintz et al 2001) and cognitive studies (Peña et al 2003).”
Resting-state functional connectivity in the human brain revealed with diffuse optical tomography (2009, background): “The portability and wearability (Obrig and Villringer, 2003) of fc-DOT systems could allow significant applications in populations that are not amenable to traditional functional neuroimaging, such as hospitalized patients and young children.”
Neuroimaging-aided differential diagnosis of the depressive state (2014, neutral): “The utility and limitations of NIRS have been discussed extensively in previous reports (Ferrari and Quaresima, 2012; Obrig and Villringer, 2003; Strangman et al., 2002a).”
Recent advances in diffuse optical imaging (2005, methodology): “The science and technology of phase measurement for NIRS and imaging has been comprehensively reviewed by Chance et al (1998b).”
Principles, techniques, and limitations of near infrared spectroscopy. (2004, methodology): “From this point of view, functional NIRS is giving a unique contribution considering that it has several advantages over existing technologies (MRI, PET, etc.) for brain imaging (Hoshi, 2003; Obrig and Villringer, 2003).”
Short separation channel location impacts the performance of short channel regression in NIRS (2011, background): “Over the past 15 years, Near-Infrared Spectroscopy (NIRS) (Gibson et al., 2005; Hillman, 2007; Hoshi, 2007; Obrig and Villringer, 2003; Villringer et al., 1993) has emerged as a complement to functional Magnetic Resonance Imaging (fMRI) for mapping the hemodynamic response associated with cerebral…”
Virtual spatial registration of stand-alone fNIRS data to MNI space (2007, background): “…tool for monitoring brain activity. fNIRS utilizes the tight coupling between neural activity and regional cerebral blood flow and monitors relative regional changes of hemoglobin concentration (reviewed in Hoshi, 2003; Koizumi et al., 2003; Obrig and Villringer, 2003; Strangman et al., 2002).”
