Sažetak
Does the neonate's brain have left hemisphere (LH) dominance for speech? Twelve full-term neonates participated in an optical topography (OT) study designed to assess whether the neonate brain responds specifically to linguistic stimuli. Participants were tested with normal infant-directed speech, with the same utterances played in reverse and without auditory stimulation. We used a 24-channel OT device to assess changes in the concentration of total hemoglobin in response to auditory stimulation in 12 areas of the right-hemisphere (RH) and 12 areas of the left-hemisphere (LH). We found that LH temporal areas showed significantly more activation when infants were exposed to normal speech than to backward speech or to silence. We conclude that neonates are born with a LH superiority to process specific properties of speech.
