Published: July 18, 2016

Upon adequate stimulation, real-time maps of cortical hemodynamic responses can be obtained by functional near-infrared spectroscopy (fNIRS), which noninvasively measures changes in oxygenated and deoxygenated hemoglobin after positioning multiple sources detectors over the human scalp. This review is aimed at giving a concise simple overview basic principles fNIRS including features, strengths, advantages, limitations, utility for evaluating behavior. The transportable/wireless commercially available systems have time resolution 1 to 10 Hz, depth sensitivity about 1.5 cm, spatial up cm. has been found suitable many applications on beings, either adults or infants/children, field social sciences, neuroimaging research, medicine. Some examples present future prospects assessing cerebral cortex function during behavior different situations (in natural situations) will provided. Moreover, most recent studies investigating interpersonal interactions adopting hyperscanning approach, consists measurement brain activity simultaneously two more people, reported.

Major depressive disorder (MDD) is a global psychiatric with no established biomarker. There growing evidence that functional near-infrared spectroscopy (fNIRS) has the ability to aid in diagnosis and prediction of treatment response MDD. The aim this review was systematically review, gather from existing studies used fNIRS signals MDD, correlations depression symptomatology, monitoring response.PubMed, EMBASE, ScienceDirect, Cochrane Library databases were searched for published English articles 1980 June 2019 focused on application (i) differentiating depressed versus nondepressed individuals, (ii) correlating turn (iii) responses depression. Studies included if they utilized evaluate cerebral hemodynamic variations patients MDD any age group. quality assessed using Newcastle-Ottawa assessment scale.A total 64 12 being longitudinal, while rest cross-sectional. More than two-thirds (n = 49) had acceptable quality. consistently demonstrated attenuated changes compared healthy individuals. have also shown promise individual symptoms various responses.This provides comprehensive updated diagnostic predictive applications Future involving larger sample sizes, standardized methodology, examination more brain regions an integrative approach, longitudinal follow-ups are needed.

Graph Theory Analysis of Functional Connectivity in Major Depression Disorder With High-Density Resting State EEG Data

IEEE Transactions on Neural Systems and Rehabilitation Engineering, Journal Year: 2019, Volume and Issue: 27(3), P. 429 - 439

Published: Jan. 24, 2019

Existing studies have shown functional brain networks in patients with major depressive disorder (MDD) abnormal network topology structure. But the methods to construct still exist some issues be solved. This paper is explore reliable and robust construction of using different coupling binarization approaches, based on high-density 128-channel resting state EEG recordings from 16 MDD normal controls (NC). It was found that combination imaginary part coherence cluster-span threshold outperformed other methods. Based this combination, right hemisphere function deficiency, symmetry breaking randomized structure were MDD, which confirmed had aberrant cognitive processing. Furthermore, clustering coefficient left central region theta band node betweenness centrality temporal alpha significantly negatively correlated level. And these metrics ability discriminate NC, indicated might served as electrophysiological characteristics for probable identification. Hence, may provide offer potential biomarkers MDD.

State-Dependent Differences in Emotion Regulation Between Unmedicated Bipolar Disorder and Major Depressive Disorder

JAMA Psychiatry, Journal Year: 2015, Volume and Issue: 72(7), P. 687 - 687

Published: May 6, 2015

Major depressive disorder (MDD) and bipolar (BD) are difficult to distinguish clinically during the depressed or remitted states. Both mood disorders characterized by emotion regulation disturbances; however, little is known about differences between MDD BD. Better insight into these would be helpful for differentiation based on disorder-specific underlying pathophysiological mechanisms. Previous studies comparing often allowed medication use, limiting generalizability validity. Moreover, patients with BD were mostly compared depressed, but not remitted, state, while state might potentially modulate BD.To investigate positive negative in medication-free 2 states: remitted.A cross-sectional study conducted from May 2009 August 2013 behavioral functional magnetic resonance imaging data of 42 MDD, 35 BD, 36 healthy control (HC) participants free psychotropic recruited several psychiatric institutions across Netherlands.A voluntary task using pictures.Behavioral blood oxygen level-dependent responses regulation.In only showed impaired (t = 3.39; P < .001; Cohen d 0.70), irrespective type associated increased dorsolateral prefrontal cortex activity those (P .008).

A Brief Review of Research Using Near-Infrared Spectroscopy to Measure Activation of the Prefrontal Cortex during Emotional Processing: The Importance of Experimental Design

Frontiers in Human Neuroscience, Journal Year: 2016, Volume and Issue: 10

Published: Oct. 20, 2016

During the past two decades there has been a pronounced increase in number of published research studies that have employed near-infrared spectroscopy (NIRS) to measure neural activation. The technique is now an accepted neuroimaging tool adopted by cognitive neuroscientists investigate fields, one which study emotional processing. Crucially, brain region important processing information prefrontal cortex (PFC) and NIRS ideally suited measuring activity this region. Compared other methods used record activation, reduces discomfort participants, makes data collection from larger sample sizes more achievable, allows measurement activation during tasks involving physical movement. However, use links between emotion cognition revealed mixed findings. For instance, whilst some report increased PFC associated with negative information, others show relation positive information. Research shows differences different tasks, yet findings also vary within similar tasks. This work reviews selection recent both healthy individuals patient populations. It highlights key argues variations experimental design could be contributing factor results. Guidance provided for future area order improve consistency growing field.
