Dear all and @rob-luke,
I am in need of advice for my PhD research, I would like to purchase the following fNIRS device, which the company provides data sheet about sensor. While my basic understanding suggests that the device is enough for PFC activity measures, I wonder whether you can confirm whether this device will be enough for the task. The reason I choose it is due to its price, and access to raw data. There is even cheaper device like Mendi but no matter how long I tried, I wont be given access because the company said they are too small and they don’t have man power to create actually such an API/SDK.
This is the device I would like your opinion about PLUX Biosignals | fNIRS Pioneer Kit
I am planing to get 2 sensors. So that I can connect right and left PFC.
Thank you so much all already for your input. I am really looking forward to your responses 
Best, David
