Qualitative clinical assessments of the recovery of awareness after severe brain injury require an assessor to differentiate purposeful behavior from spontaneous behavior. As many such behaviors are minimal and inconsistent, behavioral assessments are susceptible to diagnostic errors. Advanced neuroimaging tools can bypass behavioral responsiveness and reveal evidence of covert awareness and cognition within the brains of some patients, thus providing a means for more accurate diagnoses, more… 
The Potential Role of fNIRS in Evaluating Levels of Consciousness
The goal of this review is to summarise the studies reported on functional near-infrared spectroscopy, to discuss the technical and ethical challenges of working with patients with disorders of consciousness, and to outline promising future directions in this field.
Resting-State NIRS–EEG in Unresponsive Patients with Acute Brain Injury: A Proof-of-Concept Study
It is suggested that NIRS–EEG for monitoring of acute brain injury in the ICU is worthy of further exploration and normalization of neurovascular coupling may herald recovery of consciousness after acute head injury.
Detecting Residual Awareness in Patients With Prolonged Disorders of Consciousness: An fNIRS Study
The feasibility of using portable fNIRS technology to detect residual cognitive ability in patients with prolonged DOC by active command-driven motor imagery is confirmed.
Applications of Functional Near-Infrared Spectroscopy (fNIRS) Neuroimaging in Exercise–Cognition Science: A Systematic, Methodology-Focused Review
This review aims to summarize the current methodological knowledge about fNIRS application in studies measuring the cortical hemodynamic responses during cognitive testing, and in cross-sectional studies accounting for the physical fitness level of their participants.
Shining Light on the Human Brain: An Optical BCI for Communicating with Patients with Brain Injuries
Preliminary results highlight the potential of TR fNIRS as a tool to probe consciousness and map brain activity at the bedside and identify patients that have detectable motor imagery activity by functional magnetic resonance imaging.
Assessing Time-Resolved fNIRS for Brain-Computer Interface Applications of Mental Communication
The findings suggest that TR-fNIRS could be suitable as a BCI for patients with brain injuries.
Effects of Acupuncture on Cortical Activation in Patients with Disorders of Consciousness: A Functional Near-Infrared Spectroscopy Study
The results indicated that acupuncture can increase the concentration of HbO in the PFC and strengthen the connection strength of the left cerebral cortex, but there was not a significant correlation between the cortical hemodynamic response and the severity of DoC.
The Neurology of Death and the Dying Brain: A Pictorial Essay
The aim is to provide the reader with a thorough understanding that the boundaries within the neurology of death and the dying brain are being pushed just like everywhere else in the clinical neurosciences.
A Mini-Review on Functional Near-Infrared Spectroscopy (fNIRS): Where Do We Stand, and Where Should We Go?
This mini-review is aimed at briefly summarizing the present status of functional near-infrared spectroscopy (fNIRS) and predicting where the technique should go in the next decade. This mini-review


Functional near infrared spectroscopy as a probe of brain function in people with prolonged disorders of consciousness
Bedside detection of awareness in the vegetative state: a cohort study
Making every word count for nonresponsive patients.
It is shown for the first time with functional magnetic resonance imaging that behaviorally nonresponsive patients can use selective auditory attention to convey their ability to follow commands and communicate.
Can time-resolved NIRS provide the sensitivity to detect brain activity during motor imagery consistently?
Results indicate up to an 86% agreement between fMRI and TR-fNIRS and the sensitivity ranging from 64 to 93% with the highest value determined for the mean time of flight, which highlights the potential of TR- fNirS as a portable brain computer interface for patients with disorder of consciousness.
Spatio-temporal dynamics of multimodal EEG-fNIRS signals in the loss and recovery of consciousness under sedation using midazolam and propofol
Compared with general anesthesia, the results provide insights into critical hallmarks of sedative-induced (un)consciousness, which have similar spatio-temporal EEG-fNIRS patterns regardless of the stage and the sedative used.
Neurophysiological and Behavioral Responses to Music Therapy in Vegetative and Minimally Conscious States
Comparing electroencephalogram, heart rate variability, respiration, and behavioral responses of 20 healthy subjects with 21 individuals in vegetative or minimally conscious states suggests that further investigation is warranted to explore the use of music therapy for prognostic indicators, and its potential to support neuroplasticity in rehabilitation programs.
Specificity of Hemodynamic Brain Responses to Painful Stimuli: A functional near-infrared spectroscopy study
Functional NIRS is used to evaluate brain activation to an innocuous and a noxious electrical stimulus on healthy human subjects and the results support the notion that functional N IRS has a potential utility as an objective measure of pain.
Dissociations between behavioural and functional magnetic resonance imaging-based evaluations of cognitive function after brain injury.
Observations reveal significant challenges in developing validated functional magnetic resonance imaging-based methods for clinical use and raise interesting questions about underlying brain function assayed using these methods in brain-injured subjects.
The role of the SMART and WHIM in behavioural assessment of disorders of consciousness: clinical utility and scope for a symbiotic relationship
This paper describes and proposes complementary use of two commonly used standardised neurobehavioural assessments that both have specific aims and play an important role in behavioural assessment across the care continuum and when used together appropriately promote best practice and strengthen behavioural assessment of consciousness.
