Functional near-infrared spectroscopy

Recently, the self has become an important focus of conscious mind research. Neuroimaging studies reveal that the self emerges from the spontaneous activity of cortical midline structures (CMS). Prefrontal cortex structures are also mentioned prominently in consciousness theories such as higher-order and global workspace theories. This preliminary study aims to observe changes in frontal hemodynamics in response to self-related and non-self-related stimuli. The study included five healthy voluntary participants (mean age=25.6±5.986). Auditory stimuli containing the subject's own name (SON) wer

…Since hand flexion is the first functional recovery that can be observed, it is a promising task to evaluate the recovery process. fMRI has reported that the amplitude of neural activity varies with the intensity of movement, but the correlation between movement and neural activity itself has not been reported in functional near-infrared spectroscopy (fNIRS). To investigate this, the present study performed simultaneous fMRI and fNIRS measureme

Functional near-infrared spectroscopy (fNIRS) is now a common tool in neuroscience research, but due to the different analytical methods available, it is challenging to determine the best approach for data analysis. We investigated the effect of short channel (SC) correction on a block design experiment with auditory, visual, and audio-visual stimuli, by removing non-neuronal signals from fNIRS long channels. We tested three analysis pipelines with and without SC correction. fNIRS signal was deconvoluted using Generalized Linear Model (GLM) in which orthogonalized SC signal (first analysis), n

The amount of information exchange through the internet is less than face-to-face communication due to technical limitations of online communication. Previous studies have reported that online communication, compared with face-to-face communication, generated fewer turn-taking, less group satisfaction, and less likeable for members. Although behavioral and psychological studies which investigated the difference between online and face-to-face communication have been accumulated, the underlying neural correlates remain unclear. The purpose of this study was to investigate the difference between

…studies of social interaction using functional near-infrared spectroscopy (fNIRS) have associated increases in interbrain synchrony with positive outcome measures of cooperation, learning, and mutual understanding. Neurofeedback, a well-established method for modulating and training brain activity, has shown promise in improving cognitive functions. Consequently, it would be advantageous to determine the feasibility of creating a neurofeedback system for enhancing interbrain synchrony to potentially benefi
