Wavelet Analysis of Ischemia and Reperfusion Injury Models
H.K. Park · 2005
Fourier transform of electroencephalography (EEG) restricts EEG analysis due to its stationary properties with time change. It makes analysis difficult to ascertain the global effects of transient change in ischemia and reperfusion model. This study examines that multi-resolution analysis distinguishes different depths of ischemic insult related to the degree of residual blood flow in animal models. The results suggest that multi-resolution analysis demonstrate that little blood flowing to the brain has more detrimental effect to the EEG properties than no blood flowing, which is contrary to the common sense.
