fNIRS made easy


FNIRS device

The OctaMon is ideal for capturing brain activity while having the freedom to perform daily activities including exercise. The device consists of 8 channels covering the prefrontal cortex. Like the PortaLite, the OctaMon measures changes in oxygenation in terms of oxyhemoglobin, deoxyhemoglobin, and total hemoglobin. This device can be applied in a variety of dynamic settings as often required in neuroscience and sports science research.

This NIRS device is unique in it's kind. Other similar 8-channel NIRS systems are often non-portable, heavy, expansive, complicated and take a long time to set-up. Coming from the research field ourselves we wanted to change that. With the OctaMon we focussed on the usability and portability of NIRS while still providing the same quality of data as measured by large NIRS systems. The OctaMon is a lightweight and plug and plays device with no set-up time. It works with multichannel LED's, giving you continuous and real-time feedback in our data analysis software that is delivered with the system.



The Octamon research package makes monitoring oxygenation easy and accessible. Hyperscanning (monitoring multiple subjects at the same time) is also possible with the OctaMon, while our software provides you to combine different NIRS devices within one data stream. The subjects are able to perform physical activities like walking or running, while the device is connected to Bluetooth (up to 100 meters) to the laptop. 

The OctaMon is ideally suited to investigate cognitive functions, especially during dual tasking (for example combined with driving or walking). The prefrontal brain regions are in particular studied in working memory or attention tasks, but is also of particular interest for studying neuropathological disorders such as Alzheimer’s disease or ADHD. This is because of its strong interconnection with deeper brain regions, such as the Basal Ganglia. The headband covers a large area of the brain so it could also be used for detecting epileptic seizures.

how it works

Optical oximetry and near-infrared spectroscopy (NIRS) in particular is a tool for assessing the oxygenation status and hemodynamics of various organs, e.g. muscle and brain non-invasively. It relies mainly on two characteristics of human tissue. Firstly, the relative transparency of tissue for light in the NIR range, and secondly on the oxygenation dependent light absorbance of hemoglobin. Read more >
