Noise removal methods in NIRS can be divided into 4 categories: reducing noise based on its temporal characteristics: The instrument noise is usually in the high frequency band and thus can be removed by band pass filtering. Band pass filtering can a
香港中文大学二年级博士生胡玥为大家介绍一篇方法学文献，即基于人工神经网络重構的多通道fNIRS信号运动伪影校正。该方法不仅对心理学，还对运动科学以及康复医学等领域的研究具有重要的参考价值，热烈欢迎大家
Chunming Lu’s lab in Beijing Normal University has published a paper titled “Shared neural representations of syntax during online dyadic communication” in NeuroImage. This is another fNIRS hyperscanning study within a month (check
Let’s be frank. Compared to fMRI, NIRS has a number of intrinsic weaknesses. The signal to noise ratio is lower, the spatial resolution is (10x) lower, it can’t measure the deep brain, and it only covers a portio
This is a guest post by Ning Liu from Stanford University. — For someone who has no imaging background and just began to use fNIRS, s/he might be surprised to find out that the imaging study design is so different with study designs in other fi
Before performing any data analysis, we should check the data quality first. Below are 3 ways to do so. 1. Visual check of the time series The best pattern detector is our eyes and brains! In many cases, if we visually see the data, we know what is w
I have a friend who has been using fMRI for more than 10 years and now a professor. He heard NIRS might be a good technology to measure human brain but knew little about it. So what is the difference between NIRS and fMRI? This is probably a common q

Back in 2009 we published a paper titled “Functional near infrared spectroscopy (NIRS) signal improvement based on negative correlation between oxygenated and deoxygenated hemoglobin dynamics“. In a nutshell, we found the oxy- and deoxy-H
