Does TR-fNIRS provide sufficient sensitivity to detect brain activity during motor imagery compared to fMRI in healthy subjects?
TR-fNIRS demonstrates high agreement with fMRI and good sensitivity for detecting brain activity during motor imagery, highlighting its potential as a portable brain-computer interface.
Abdalmalak et al. (2017) conducted an observational in Healthy subjects (n=15). Time-resolved functional near infrared spectroscopy (TR-fNIRS) vs. Functional magnetic resonance imaging (fMRI) was evaluated on Agreement between fMRI and TR-fNIRS and sensitivity in detecting brain activity during motor imagery. Time-resolved fNIRS demonstrated up to 86% agreement with fMRI and a sensitivity ranging from 64% to 93% for detecting brain activity during motor imagery.
