Assessing NIRS signal quality – Implementation of the Signal Quality Index (SQI)

Achieving good signal quality is crucial for (f)NIRS data acquisition and analysis, but often difficult to determine. Therefore, we developed an algorithm named SQI (Signal Quality Index) which rates NIRS signal quality. Read this blogpost to learn more on how this SQI is specified and how it can be implemented in your research.

The use of Inertial Measurement Unit (IMU) to detect motion artifacts

Due to its portability, NIRS and fNIRS devices are often used to measure brain and muscle activity during studies that involve movement. To detect motion artifacts that might occur during these experiments, some of our devices, for instance, Brite and PortaLite MKII, incorporate an inertial measurement unit (IMU). Read this blog post, to learn more about the technology behind IMU and how it is used to detect motion artifacts.

Measuring brain activity during playing a competitive checker game – a fNIRS hyperscanning mini study

In hyperscanning, brain activity and connectivity of multiple subjects are measured simultaneously during social interaction, for instance in competitive situations. fNIRS is often used as neuroimaging technology for hyperscanning in cognitive studies due to its portability and relative insensitivity to movement artifacts. In an internal mini-study, we tested the use of Brite Frontal to perform hyperscanning while participants played a competitive game of checker.

Combining Virtual Reality and wearable fNIRS

The application of Virtual Reality (VR) is becoming increasingly important in clinical and psychological research, for instance in exposure therapy or neurorehabilitation. fNIRS can be used to monitor brain activity during application of VR. We tested simultaneous use of VR and fNIRS with our new device, the Brite Frontal. Read in this blogpost, how this went and which advantages using fNIRS during VR application can demonstrate.

The PROHEALTH Project – Investigating orthostatic hypotension in elderly by performing continuous NIRS measurements in a home-based setting

Orthostatic hypotension is a form of low blood pressure that is characterized by drops in blood pressure when standing up from a lying or sitting position and frequently occurs in elderly subjects. The PROHEALTH project aims to implement home-based and continuous Near-Infrared-Spectroscopy (NIRS) measurements to detect orthostatic hypotension using the PortaLite (MKII). Read this blog post more about the PROHEALTH project and which targets are followed to reach the goal.

The Starstim fNIRS - Combining tES brain stimulation and EEG + fNIRS neuroimaging in one headcap

Starstim fNIRS is the most adaptable solution to combine tES brain stimulation with EEG and fNIRS neuroimaging in one single wireless and wearable system – and what makes it the most versatile solution for researchers and clinicians in many application areas. The possibility to combine tES with multiple neuroimaging modalities in one device facilitates altering human behavior and acquiring a more complete picture of the brain. It further increases application possibilities and reduces set-up and measurement time.
