Binaural interaction (BI) components in brain-stem auditory evoked potential (BAEP) and their changes with stimulus intensity and repetition rate were examined in human adult. Seven BI components were identified, which occurred between the latency range of 5 and 11 ms and coincided consistently with the latency range of BAEP waves IV-VII. Waves DV and DVII,(More)
AIM To clarify further the influence of intrauterine growth retardation (IUGR) on early neural development. METHODS In 30 small-for-gestational age (SGA) preterm infants at term, brainstem auditory-evoked responses (BAERs) were recorded with clicks of different repetition rates. All infants had a birthweight < 3rd centile, without any other major(More)
Auditory neural responses to acoustic stimuli of different rates were studied by analyzing changes in brainstem auditory evoked responses (BAER) with increasing repetition rate of clicks, or rate-dependent changes, in 62 very preterm babies (gestation 24-32 wk). None had perinatal asphyxia or major complications at the time of testing (37-42 wk(More)
Relative maturation of peripheral and central regions of the neonatal brainstem was studied using brainstem auditory evoked responses in 174 healthy preterm infants (gestational age 30-36 wk). From 30- to 42-wk postconceptional age (PCA), I-III and III-V intervals shortened with increasing age. It was difficult to detect any apparent differences in(More)
OBJECTIVE To examine brain-stem auditory function at term in very preterm infants who suffered chronic lung disease (CLD). METHODS Brain-stem auditory evoked response (BAER) was recorded at term with clicks in 25 very preterm infants with CLD and no concomitant other major perinatal problems. RESULTS Compared to those in normal term controls, BAER wave(More)
AIM To examine the process of change in hearing threshold during the neonatal period after perinatal hypoxia-ischaemia. METHODS The threshold of brainstem auditory evoked responses (BAER) was measured serially during the first month after birth in 92 term babies who suffered hypoxia-ischaemia. RESULTS The mean BAER threshold in these babies was(More)
OBJECTIVE To examine whether late preterm infants with perinatal problems are at risk of brainstem auditory impairment. METHODS 68 high-risk late preterm infants (gestation 33-36 weeks) with perinatal problems or conditions were studied at term using maximum length sequence brainstem auditory evoked response. The controls were 41 normal term infants and(More)
Genetic polymorphisms of methylenetetrahydrofolate reductase (MTHFR) have been suggested as being associated with cerebral palsy (CP) but the evidence is uncertain. The purpose of this study was to investigate whether MTHFR gene polymorphisms contribute to the development of CP in Chinese infants. For this study, 169 health controls and 159 infants with CP(More)
Neurons in the deeper layers of the superior colliculus (SC) have spatially tuned receptive fields that are arranged to form a map of auditory space. The spatial tuning of these neurons emerges gradually in an experience-dependent manner after the onset of hearing, but the relative contributions of peripheral and central factors in this process of(More)
AIM The aim of this study was to detect any differences in brainstem auditory evoked responses (BAERs) to different click rates between moderately preterm and term infants. METHODS BAER was recorded with 21-91/s clicks at term age (37-42 weeks postconceptional age) in 39 moderately preterm infants (gestation 33-36 weeks). The results were compared with 37(More)
