Does Facebook’s “mind reading” project use NIRS?

Facebook just announced that they are experimenting with mind-reading technology using optical neuro-imaging systems. This technology will allow people to type words by thoughts at 100 words per minute. Check out the news here. Wow! This is unbelieva

Updated loadHitachiText.m

Some labs have been using our script readHitachiData.m to load NIRS data from Hitachi ETG machines. We recently found that some output MES data contains abnormal timestamp. For example, the timestamp should be like 16:49:25.406 But for some rows (alt

Chin rest (head holder) device for NIRS

When we set up our NIRS lab back in 2008, we needed a device to prevent participants’ head movement during the experiment and during the digitizer measurement. Even though NIRS is tolerant to head motion, we still want to minimize it. During th

We contributed to MatLab (wavelet toolbox)

We use MatLab a lot! It’s the major program for brain imaging data analysis in our lab. However, I never thought we could actually contribute to MatLab’s development. In MatLab 2016, there is a toolbox called Wavelet Toolbox. If you read

Communications between two MatLabs (1) over file

Ref to: Communications between two MatLabs (2): over socket It’s common that two MatLab programs needs to communicate. For instance, one program is collecting the brain imaging data but not display them, and the other program is to display the

Some tips to use wavelet toolbox

Wavelet toolbox is a useful tool to study hyperscanning data. Many recent publications on NIRS hyperscanning use wavelet coherence to quantify the relationship between two interacting brains (e.g. Baker et al 2016, Nozawa et al 2016). You can see mor

Just published a paper: Men vs Women, are they…

We just published a big and long study. It is a NIRS hyperscanning study aiming to investigate the brain difference between men and women during cooperation. We have scanned 222 people! And it is one of the largest NIRS study I have seen. And it is a
