“…The use of NIRS electrodes on the forehead has been shown to be appropriate for monitoring changes in cerebral oxygenation in the prefrontal area. 18,19 The experimentalist visually ensured good contact for all light sources and photodetectors before the experiment started. In addition, the NIRS software included a module that identified channels Annals of Clinical Neurophysiology Volume 20, Number 2, July 2018 with saturated or low signals based on an empirically tested range of light intensities.…”

Near-infrared spectroscopy (NIRS) monitoring has been used mainly to detect reduced perfusion of the brain during orthostatic stress in order to assess orthostatic intolerance (OI). Many studies have investigated the use of NIRS to reveal the pathophysiology of patients with OI. Research using NIRS in other neurological diseases (e.g., stroke, epilepsy, and migraine) is continuing. NIRS may play an important role in monitoring the regional distribution of the hemodynamic flow in real time and thereby reveal the underlying pathophysiology and facilitate the management of not only patients with OI symptoms but also those with various neurological diseases.Key words: Orthostatic intolerance; Near-infrared spectroscopy; Clinical neurology INTRODUCTIONMany studies have investigated the hemodynamics and functions of the brain in various fields.1 Several noninvasive methods have been introduced in recent decades for measuring neuronal activity in the brain. 2 Neurophysiological techniques such as electroencephalography, magnetoencephalography, and event-related potentials offer the ability to measure overall changes in the electromagnetic field with an excellent time resolution, but these methods have poor spatial resolution. On the other hand, brain imaging techniques such as positron-emission tomography (PET) and functional magnetic resonance imaging (fMRI) have greatly increased our knowledge about neural circuitry. However, PET is highly sensitive to motion artifacts, confines the patient, and involves the injection of radioactive materials. Although fMRI is noninvasive and has excellent spatial resolution, it is expensive, highly sensitive to motion artifacts, and difficult to integrate with other imaging modalities. 3,4 Near-infrared spectroscopy (NIRS) was introduced as a new neuroimaging modality for Principle of NIRSNIRS is a noninvasive optical imaging tool for observing changes in the hemodynamics in the prefrontal area that is based on measuring the concentrations of HbO and HbR in the blood. Since Franz Jöbsis first studied the oxygenation of living tissues, NIRS has been extensively applied in imaging studies of brain activation. 6 The physiological activation of neurons leads to an imbalance between oxygen supply and utilization, increasing the concentration of HbO and decreasing the concentration of HbR. Most tissues are relatively transparent to light in the near-infrared range from 700 to 900 nm, and photons interact with tissues via absorption and scattering. This means that near-infrared light is less absorbed and scattered by tissue than is light at other wavelengths. 7 This range of wavelengths is often called an optical window since the light can easily pass through most tissues; however, it is reflected by HbO and HbR, and hence the absorption and scattering of light used for NIRS can provide information relevant to neural activity. 8 This light penetrates several centimeters through tissue and can still be detected (Fig. 1). The NIRS system consists of a light source and a photodetector. The l...

“…In the past twenty years, fNIRS has been rapidly developed to be an effective and easy-tooperate tool to monitor human brain function and has been widely applied in various fields, especially for studies on children with ASD [22,23]. In the present study, we employed fNIRS to detect the prefrontal response to joint and non-joint attention stimuli in terms of activation and functional connectivity and compared the differences between ASD and TD children.…”

“…A fMRI study has revealed that the ventromedial frontal cortex, the left superior frontal gyrus (BA10), cingulate cortex, and caudate nuclei of typical adults was activated during joint attention [11]. Although a fNIRS study support the role of right prefrontal cortex in self-face cognition [34]. In line with some previous studies, our results showed the importance of prefrontal cortex in joint attention experience of TD children, and revealed the atypical activation and connectivity pattern of the left prefrontal cortex during joint attention of children with ASD.…”

Autism spectrum disorder (ASD) is a neuro-developmental disorder, characterized by impairments in one's capacity for joint attention. In this study, functional near-infrared spectroscopy (fNIRS) was applied to study the differences in activation and functional connectivity in the prefrontal cortex between children with autism spectrum disorder (ASD) and typically developing (TD) children. 21 ASD and 20 TD children were recruited to perform joint and non-joint attention tasks. Compared with TD children, children with ASD showed reduced activation and atypical functional connectivity pattern in the prefrontal cortex during joint attention. The atypical development of left prefrontal cortex might play an important role in social cognition defects of children with ASD. ©2015 Optical Society of America

“…This configuration enabled us to detect signals from 16 differential channels spread over the bilateral frontal region. The center of the probe matrix was placed on Fpz (International 10-10 system), and the bottom left and bottom right corners were located around F7 and F8, respectively, in line with a previous report [23]. Detected NIRS signals were sent to a separate data collection computer.…”

Background: Executive function is an assemblage of high-level cognitive domains (inhibition, working memory, planning, fluency, and shifting) that facilitate the inhibition of incorrect behaviors and the selection of appropriate behaviors according to context and goals. A deficit in cognitive shifting might be a core symptom of attention-deficit hyperactivity disorder. However, previous studies addressing this issue used neurobehavioral tests, which might not be specific enough to measure cognitive shifting. The purpose of the present study was to compare cognitive shifting among children with attention-deficit hyperactivity disorder and typically developing children using a Dimensional Change Card Sort task while simultaneously measuring patterns of neural activity in the prefrontal cortex.
