One of the first steps in our fNIRS research is designing our probeset–deciding where sources and detectors should be placed on the head. Here are some of the methods we use to ensure that our probeset is suitable for the project:
The International 10-20 System
The International 10-20 System is useful for determining anchor points for your probe configuration. Positioning our probeset relative to anchor points will ensure that the probe is at the same anatomical location for each of our participants.

Depending on the needs of the projects, our lab uses different types of caps, ranging from band rubber caps to full easy caps. And our lab have caps with different sizes. This ensures that we target the region of interest effectively and remove any noise such as hair and reduce discomfort for the participants.
For most of our projects, we use the software E-Prime to develop and present our experimental paradigms. E-Prime has the capability to send triggers to the CW6 software, allowing us to mark when in our data certain things were presented by E-Prime. Click here if you want to learn how we do it.
