“…The results of MMN latencies are in keeping with the findings of auditory cortex maturation found in normal hearing children (17,20), i.e., the MMN latency becomes shorter in association with normal auditory cortex development and 18 maturation (17,20,28). Moreover, such latency decreases from M3 to M6 correlated significantly with the increases in the CAP scores.…”

“…deviant stimulus vs. standard stimulus) in the auditory stimulus stream, and its largest amplitude is generally recorded over the fronto-central scalp areas at around 200ms post stimulus (13,14). It represents neurophysiologic changes in the brain's electrical activity in response to auditory discrimination (15), and therefore, it is considered to be an objective measurement to assess the auditory cortical function as well as central auditory processing function (16,17). Cheour et al (17) reported that the MMN presented in 8 of 12 full-term neonates (66.7%) and all of six 3-month-old infants (100%).…”

Objective: The aim of this study was to investigate auditory cortical development using mismatch negativity (MMN) in pre-lingual severe to profound hearing-impaired children from switching on the cochlear implantation (CI) and 6 months post-CIs Results: Although the MMN incidence was much lower at the periods of M0 and M1, significantly higher MMN incidence was found in M3 and M6. The MMN latencies decreased significantly from M3 to M6, but no significant difference in the amplitudes was found between these periods. There was a negative correlation between the increment of CAP scores and decrement of MMN latency from M3 to M6.Conclusions: MMN incidence increases and latency decreases are likely to be the objective and noninvasive indicators for evaluating auditory central development at an 4 early stage in children post cochlear implantation. Moreover, the latency decreases from M3 to M6 correlated significantly with the increases of the CAP scores, indicating a fast maturation period, which might be a key period for auditory rehabilitation.

Maturation of auditory perceptual and discrimination process within the first two years of life is investigated in healthy infants by examining event-related potentials (ERPs). High-density EEG signals were recorded from the scalp monthly between 3 and 24 months of age. Two types of stimuli (100 vs. 100 Hz for standard stimuli; 100 vs. 300 Hz for deviant stimuli; occurrence rate: 85:15%) were presented using an oddball paradigm. Latencies and amplitudes were compared across development. The results showed that latencies of P 150 , N 250 , P 350 , and N 450 components gradually decreased with increasing age. Amplitudes of the N 250 and P 350 components gradually increased and reached the maximum at 9 months, and then gradually decreased with the increase of age. Mismatch negativity was not obvious at 3 months of age, but was seen at 4-5 months and became robust after 6 months. Robust late positivity was recorded at all ages. These mismatch responses were noticeable in the frontal, central, and parietal areas, and the maximal MMN amplitude distribution gradually moved from the parietal area to the frontal area across the age range. Two important periods-one around 6 months and the other around 9 months are suggested in the maturation of auditory central system. Dynamical changes in the underlying source strengths and orientations may be principal contributors to ERP morphological changes in infants within the first 24 months.

“…Repetitive auditory stimulation in sleeping human newborns elicits a positive deflection in the event-related potential (ERP), with a latency of about 200-300 ms (Ohlrich et al, 1972;Ellingson et al, 1974;Kurtzberg et al, 1984;Novak et al, 1989;Cheour et al, 1998Cheour et al, , 2002aKushnerenko et al, 2002b). Recently, several studies showed responses at similar latencies (Lengle et al, 2001;Huotilainen et al, 2003;Cheour et al, 2004;Kujala et al, 2004;Pihko et al, 2004) in recordings of evoked magnetic fields (ERFs).…”
