fNIRS (Functional Near-Infrared Spectroscopy) uses radio frequencies (RF), specifically intensity modulation in the radio frequency (typically around 100 MHz) range, in its Frequency Domain (FD-fNIRS) technique to measure brain activity by analyzing how light scatters and gets absorbed by hemoglobin, providing more detail than continuous-wave (CW) fNIRS by detecting phase shift and amplitude attenuation to better separate absorption from scattering, helping to reduce noise and understand hemodynamic changes.

fMRI (functional Magnetic Resonance Imaging) BCI signal acquisition measures brain activity by detecting the Blood-Oxygen-Level-Dependent (BOLD) signal, a proxy for neural activity, using powerful magnets and radio waves, offering high spatial resolution but slower temporal response than EEG, capturing metabolic changes related to thought or intent within a specialized scanner environment for closed-loop neurofeedback systems.
