AB  - BACKGROUND AND OBJECTIVE: The relationship between EEG source signals and 
      action-related visual and auditory stimulation is still not well-understood. The 
      objective of this study was to identify EEG source signals and their associated 
      action-related visual and auditory responses, especially independent components 
      of EEG. METHODS: A hand-moving-Hanoi video paradigm was used to study neural 
      correlates of the action-related visual and auditory information processing 
      determined by mu rhythm (8-12 Hz) in 16 healthy young subjects. Independent 
      component analysis (ICA) was applied to identify separate EEG sources, and 
      further computed in the frequency domain by applying-Fourier transform ICA 
      (F-ICA). RESULTS: F-ICA found more sensory stimuli-related independent components 
      located within the sensorimotor region than ICA did. The total number of 
      independent components of interest from F-ICA was 768, twice that of 384 from 
      traditional time-domain ICA (p < 0.05). In the sensory-motor region C3 or C4, the 
      total source signals intensity distribution values from all 14 subjects was 23.00 
      (Mean 1.64 +/- 1.17) from F-ICA; which was more than the 10.5 (Mean 0.75 +/- 0.62) 
      from traditional time-domain ICA (p < 0.05). Furthermore, the intensity 
      distribution of source signals in the C3 or C4 region was statistically 
      significant between the ICA and F-ICA groups (strong 50 vs. 92%; weak 50 vs. 8% 
      retrospectively; p < 0.05). In the Pz region, the total source signal intensity 
      distribution from F-ICA was 12.50 (Mean 0.89 +/- 0.53); although exceeding that of 
      traditional time-domain ICA 8.20 (Mean 0.59 +/- 0.48), the difference was not 
      statistically significant (p > 0.05). CONCLUSIONS: These results support the 
      hypothesis that mu rhythm was sensitive to detection of the cognitive expression, 
      which could be reflected by the function in the parietal lobe sensory-motor 
      region. The results of this study could potentially be applied into early 
      diagnosis for those with visual and hearing impairments in the near future.
