TI  - Hemispheric balance in coding speech and non-speech sounds in Chinese 
      participants.

AB  - To study the role of neuromagnetic auditory approximately 100-ms responses 
      (N100m) in phonetic processing, we recorded N100m in 24 right-handed Chinese 
      participants using a whole-head neuromagnetometer. The stimuli included vowel /a/ 
      and consonant-vowels /ba/ and /da/, spoken by one Chinese speaker, and a 1-kHz 
      tone. N100m to tones was larger in the right hemisphere, whereas that to speech 
      sounds was bilaterally similar. The amplitude ratio of speech to non-speech N100m 
      was larger in the left hemisphere. N100m dipoles in the left hemisphere were 
      approximately 2 mm more anterior for speech than for tone stimuli. The results 
      suggest that N100m reflects both acoustics and phonetic processing. Moreover, the 
      ratio of speech to non-speech activation in individual hemispheres may be useful 
      for language lateralization.
