Abstract(in English) | Near-infrared spectroscopy (NIRS) is a non-invasive method for measuring relative changes in tissue concentration of oxygenated, deoxygenated and total hemoglobin. This method provides a non-invasive functional brain mapping technique because the brain activity is closely coupled with local hemoglobins concentration changes. Cerebral activation of auditory areas for phoneme and pitch contrasts were measured by multi-channel NIRS for 0-5 y.o. infants. The subjects of 1-5 y.o. showed left dominance for phoneme processing relative to pitch processing. This result was comparable to that of right-handed adults [Furuya et al., Neurosci Res S24: S77, 2000]. The subjects of the first year of life did not show significant left dominance. |
