摘要

The low-frequency oscillation (LFO) has been observed a positive or negative pike around 0.1 Hz, which is related to the specified brain function activities. Functional near-infrared spectroscopy (fNIRS) was used to simultaneously and noninvasively detect LFOs of multiple cerebral hemodynamics parameters. Based on local Fourier transform (LFT), we extract the amplitude of deoxy-Hb concentration signal at 0.1 Hz in the frequency domain and found a phenomenon which is correlated to that accuracy/respond time (accuracy/ RT) was stable when the deoxy-Hb concentration is at low level in the middle. Afterwards, we propose two feasible applications after doing some research: monitoring the fatigue driving level and evaluating the brain activity potential of human. This study observed LFOs in brain activities and showed a strong potential of LFOs in exploring brain functions.
