Key result
Continuous-wave fNIRS reliably captured supplementary motor area activation during motor execution and motor imagery, demonstrating spatial specificity and task sensitivity comparable to fMRI.
Why the study?
Neurofeedback applications require that functional near infrared spectroscopy can measure signals from the target brain region of interest, such as the supplementary motor area.

Can continuous-wave fNIRS reliably measure supplementary motor area activation during motor execution and motor imagery compared to fMRI in healthy older adults?
Continuous-wave fNIRS is a valid tool for measuring supplementary motor area activation during motor imagery, supporting its potential use in neurofeedback applications.
Klein et al. (2022) conducted a cross-sectional in Healthy older adults (n=16). Continuous-wave fNIRS vs. fMRI was evaluated on Spatial specificity and task sensitivity of SMA activation. Continuous-wave fNIRS reliably captured supplementary motor area activation during motor execution and motor imagery, demonstrating spatial specificity and task sensitivity comparable to fMRI.
