If you have digitizer data, then NFRI tool can be very useful to visualize these data on a brain. If you can’t access youtube, see below:
Honda has developed new brain-machine interface (BMI) technology that allows humans to control the Asimo humanoid robot simply by thinking certain thoughts. The technology is based on combined EEG and NIRS. The system reportedly has an accuracy rate
Raspberry Pi for research labs (3) Raspberry Pi for research labs (1) We recently used a smartphone to measure participants’ head motion during an NIRS experiment and got decent results. Smartphone is easy to use, but its size is relatively bul
Is NIRS able to measure signal from deep brain structure, such as amygdala? The short answer is no. NIRS is only able to measure the surface of the brain. This is a serious limitation of NIRS compared to fMRI which is able to measure the entire brain
Is it possible to use a smartphone to measure head motion in a NIRS study? Is it reliable? After all, smartphones are so popular right now and everybody has it. It would make head motion measurement much more convenient than a traditional stand-alone
We know the hemodynamic signal measured by fMRI (or NIRS) is delayed respective to the onset of stimuli. But how long is the delay? Many people think it takes about 2s for the signal to arise. Actually the delay varies from region to region. As shown
Description: The subject is myself. I did a simple finger tapping task. I continuously tapped my right hand on the table for 10s, then rest for 20s. Then repeat this tapping-rest cycle for 20 times. NIRS signals were recorded by Hitachi ETG-4000. The
We have an interesting challenge in one of our projects. In our neuroimaging experiment, we need the participant to play a computer game while his brain is scanned (using a NIRS device ETG 4000 in this case). As you can imagine, we need to start the
