Abstract: Purpose: The objective of this study was to assess the spontaneous cerebral oscillations based on the wavelet transform of near-infrared spectroscopy (NIRS) signals in subjects at risk for atherosclerotic stroke. Methods: A total of 32 subjects were recruited from the university to participate in this study: 20 were normal subjects (age = 59.6 ?? 10.2 year) and the other 12 were subjects at risk for ischemic stroke (age = 60.2 ?? 10.1 year).The cerebral oxygenation signal was monitored for 10 min from the left prefrontal lobe using NIRS. Results: With spectral analysis based on w
