Extracting heartrate from optical signal of functional near-infrared spectroscopy based on mathematical morphology [PDF]
Journal of Innovative Optical Health Sciences, 2018 Functional near-infrared spectroscopy (fNIRS), as a new optical functional neuroimaging method, has been widely used in neuroscience research. In some research fields with NIRS, heartrate (HR) (or heartbeat) is needed as useful information to evaluate ...

Similarity analysis of functional connectivity with functional near-infrared spectroscopy [PDF]
Journal of Biomedical Optics, 2015 One of the remaining challenges in functional connectivity (FC) studies is investigation of the temporal variability of FC networks. Recent studies focusing on the dynamic FC mostly use functional magnetic resonance imaging as an imaging tool to investigate the temporal variability of FC.

Spatial Release From Informational Masking: Evidence From Functional Near Infrared Spectroscopy
Trends in Hearing, 2018 Informational masking (IM) can greatly reduce speech intelligibility, but the neural mechanisms underlying IM are not understood. Binaural differences between target and masker can improve speech perception.

Subject-independent decoding of affective states using functional near-infrared spectroscopy.
PLoS ONE, 2021 Affective decoding is the inference of human emotional states using brain signal measurements. This approach is crucial to develop new therapeutic approaches for psychiatric rehabilitation, such as affective neurofeedback protocols.

Evaluating feasibility of functional near-infrared spectroscopy in dolphins
Journal of Biomedical Optics, 2023 Using functional near-infrared spectroscopy (fNIRS) in bottlenose dolphins (Tursiops truncatus) could help to understand how echolocating animals perceive their environment and how they focus on specific auditory objects, such as fish, in noisy marine settings.To test the feasibility of near-infrared spectroscopy (NIRS) in medium-sized marine mammals ...

Development of an fNIRS-Based Neurofeedback System to Modulate Prefrontal Asymmetry
IEEE AccessFunctional near-infrared spectroscopy (fNIRS) is promising for neurofeedback (NF) applications and warrants further investigation. In this study, we developed an fNIRS-based NF system to modulate the hemodynamic asymmetry of the prefrontal cortex, which ...
