Abstract Compared to functional magnetic resonance imaging (fMRI), near infrared spectroscopy (fNIRS) has several advantages that make it particularly interesting for neurofeedback (NFB). A pre-requisite NFB applications is with fNIRS, signals from the brain region of interest can be measured. This study focused on supplementary motor area (SMA). Healthy older participants (N = 16) completed separate continuous-wave (CW-) fNIRS and (f)MRI sessions. Data were collected executed imagined hand...
The expansion of functional near-infrared spectroscopy (fNIRS) methodology and analysis tools gives rise to various design analytical decisions that researchers have make. Several recent efforts developed guidelines for preprocessing, analyzing, reporting practices. For the planning stage fNIRS studies, similar guidance is desirable. Study preregistration helps transparently document study protocols before conducting study, including materials, methods, analyses, thus, others verify,...
The optical brain imaging method functional near-infrared spectroscopy (fNIRS) is a promising tool for real-time applications such as neurofeedback and brain-computer interfaces. Its combination of spatial specificity mobility makes it particularly attractive clinical use, both at the bedside in patients' homes. Despite these advantages, optimizing fNIRS use requires careful attention to two key aspects: ensuring good maintaining high signal quality. While detects superficial cortical...
Researchers using functional near infrared spectroscopy (fNIRS) are increasingly aware of the problem that conventional filtering methods do not eliminate systemic noise at frequencies overlapping with task frequency. This is a when signals averaged for analysis, even more so single trial data used as in online neurofeedback or BCI applications where insufficiently preprocessed means feeding back instead brain activity looking brain-behavior relationships on trial-by-trial basis. For...
Functional near-infrared spectroscopy (fNIRS) is a promising tool for neurofeedback (NFB) or brain-computer interfaces (BCIs). However, fNIRS signals are typically highly contaminated by systemic activity (SA) artifacts, and, if not properly corrected, NFB BCIs run the risk of being based on noise instead brain activity. This can likely be reduced correcting SA, in particular when short-distance channels (SDCs) available. Literature comparing correction methods with and without SDCs still...
A shared understanding of terminology is essential for clear scientific communication and minimizing misconceptions. This particularly challenging in rapidly expanding, interdisciplinary domains that utilize functional near-infrared spectroscopy (fNIRS), where researchers come from diverse backgrounds apply their expertise fields such as engineering, neuroscience, psychology. The fNIRS Glossary Project was established to develop a community-sourced glossary covering key terms, including...
The hepatic Na+-taurocholate cotransporting polypeptide NTCP/SLC10A1 is important for the uptake of bile salts and selected drugs. Its inhibition results in increased systemic salt concentrations. NTCP also entry receptor hepatitis B/D virus. We investigated interindividual SLC10A1/NTCP expression using various omics technologies. mRNA expression/protein abundance was quantified well-characterized 143 human livers by real-time PCR LC-MS/MS-based targeted proteomics. Genome-wide SNP arrays...
Neurofeedback allows individuals to monitor and self-regulate their brain activity, potentially improving human function. Beyond the traditional electrophysiological approach using primarily electroencephalography, haemodynamics measured with functional magnetic resonance imaging (fMRI) more recently, near-infrared spectroscopy (fNIRS) have been used (haemodynamic-based neurofeedback), particularly improve spatial specificity of neurofeedback. Over recent years, especially fNIRS has...
