The influence of extra-cerebral vasculature on the efficacy of the short-separation regression approach applied to fNIRS data analysis
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Functional near-infrared spectroscopy (fNIRS) is a non-invasive, portable, and inexpensive optical neuroimaging technique with respectable spatial and temporal resolution. fNIRS is, however, susceptible to extra-cerebral physiological noise, potentially compromising its sensitivity to detect task-related brain activation. Previous studies have addressed this issue by correcting fNIRS signals with additional information recorded exclusively from extra-cerebral regions using short-distance channels (SDCs). This method, termed short-separation regression (SSR), can improve fNIRS-signal quality and the sensitivity to detect task-related brain activation. However, it is unclear whether the efficacy of SSR depends on factors such as the presence of blood vessels in the channel’s vicinity. Here, we combined anatomical, functional and angiograp' .
