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
Assume you are doing a correlation study between two brain areas, A and B. For each subject, you get a single value, the correlation between A and B. And you have 100 subjects. How do you know if the mean of the correlation is significantly different

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
Undoubtedly some people are very successful in making money by developing a smartphone app. Back in 2012 I developed an app called “Handbook of Brain” which is a collected resources of brain anatomy, function and diseases. I put the app i
