WebInfrared Spectroscopy (fNIRS) is a method with relatively precise spatial resolution (see Aslin & Mehler, 2005; Minagawa-Kawai et al., 2008). NIRS allows estimation of the hemodynamic response on the immediate cortical surface at a maximum depth of about 2.5–3cm from the light source. Thus, at least on the cortical surface, NIRS Web5 Feb 2024 · As to obtain higher temporal resolution for fNIRS-BCI, several studies demonstrated the detection of the initial dip may be useful. The initial dip refers to an early small decrease of the concentration of oxy-Hb and is closely associated with neuronal metabolism. fNIRS-based BCI using initial dip detection could reduce the command …
WebNear-infrared spectroscopy (NIRS) was originally designed for clinical monitoring of tissue oxygenation, and it has also been developed into a useful tool in neuroimaging studies, with the so-called functional NIRS (fNIRS). With NIRS, cerebral activation is detected by measuring the cerebral hemoglobin (Hb), where however, the precise correlation between …
