Use of fNIRS to assess resting state functional connectivity

Reduced interhemispheric functional connectivity of children with autism spectrum disorder: evidence from functional near infrared spectroscopy studies

“…We cut and removed the motion segment from the data. Secondly, in order to remove possible physiological noise and signals beyond our study, a band pass filtered between 0.009 and 0.08 Hz [6][7][8][9] was used. Thirdly, the global signal, which was estimated by averaging the time series over all channels, was removed by linear regression [41].…”

“…fNIRS has high temporal resolution and reasonable spatial resolution. It also provides non-invasive and portable imaging environment which could be easily applied to clinical populations, children and neonates [6][7][8], especially on children with neurological disorder. So far, fNIRS has been applied to children with attention deficit hyperactivity disorder (ADHD), epilepsy, speech and language delay, preterm birth/early brain injury, ASD and infant at risk of ASD (for a review, see [9]), showing that fNIRS can be an effective tool to reveal the biological deficits underlying cognitive dysfunction of atypically developed brain and provide new perception for early diagnosis, assessment and treatment for the symptoms.…”

Functional Brain Imaging Using Non-Invasive Non-Ionizing Methods: Towards Multimodal and Multiscale Imaging

“…NIRS is a very portable technique (Atsumori et al, 2009) and has been proposed as a useful technology for non-invasive brain-computer interfaces (Power et al, 2010;Coyle et al, 2004Coyle et al, , 2007Sitaram et al, 2007;Utsugi et al, 2008). NIRS has been used to study brain activity in both event-related tasks and resting states (Boecker et al, 2007;Herrmann et al, 2005;White et al, 2009;Honda et al, 2010;Zhang et al, 2010;Lu et al, 2010). It has been also proposed as useful alternate in experimental paradigms which are difficult to perform in the MRI scanner, such as face-to-face communication (Suda et al, 2010) or driving (Tomioka et al, 2009).…”

Funtional Near Infrared Spectroscopy Study of Language, Joint Attention and Motor Skills

“…During the jaw movement (J) stimuli, the participants were asked to randomly move their jaw without actually speaking. During the rest (R), the participants were asked to minimize their thoughts and look at a white wall (Murias et al 2007;Lu et al 2010;Zhang et al 2010;Chaudhary et al 2011). …”
