New Citations | fNIRS in Mind & Muscle Research
fNIRS technology adds real-time imaging to your lab without the drawbacks of functional MRI or other imaging techniques that are expensive, time-consuming, and complex to set up and run. fNIRS optical imaging systems are ideal for research and education, to study the brain or muscle function. Here’s a sampling of recent fNIRS citations…
Similarities and differences in the induction and regulation of the negative emotions fear and disgust: A functional near infrared spectroscopy study. Scandinavian Journal of Psychology. Sklivanioti Greenfield, M., Wang, Y., & Msghina, M. (2022)
- In this multimodal study of emotion, researchers compared the induction (EI) and effortful regulation (ER) with reappraisal of fear and disgust in healthy subjects using functional near infrared spectroscopy (fNIRS) in conjunction with electrodermal activity (EDA). An imaging sensor was placed on the participant’s forehead to record different parts of the prefrontal cortical mantle. The sensor uses four infrared light sources emitting at two different wavelengths (730 and 850 nm) and ten detectors separated by a distance of 2.5 cm, giving a total of 16 channels of data.

Giuriato, G., Venturelli, M., Matias, A., Soares, E. M., Gaetgens, J., Frederick, K. A., & Ives, S. J. (2022).
- Researchers investigating how capsaicin influences neuromuscular fatigue monitored microvascular oxygenation as an objective physiological measure vs. subjective participant perception. The NIRS technique records continuous, noninvasive, microvascular oxygenation during muscle activation. Muscle oxygenation measurements include oxygenated (HbO2), deoxygenated (HHb), and total (Hbtot) hemoglobin levels.
Influence of Cognitive Task Difficulty in Postural Control and Hemodynamic Response in the Prefrontal Cortex during Static Postural Standing. Applied Sciences, 12(13), 6363. Saraiva, M., Paszkiel, S., Vilas-Boas, J. P., & Castro, M. A. (2022).
- When we perform two or more tasks concurrently, adequate postural control is essential for success. Researchers designed a study to evaluate and compare the center of pressure (CoP) behavior and the hemodynamic response of the prefrontal cortex during static postural standing while performing cognitive tasks of increasing levels of difficulty. They used an fNIRS System to measure oxyhemoglobin ([oxy-Hb]), deoxyhemoglobin ([deoxy-Hb]), and total hemoglobin ([total-Hb]) concentrations.
