| 内容記述 | As with the brainstem evoked potentials (BEPs) and the late event-related evoked potentials (ERPs), recent investigations have shown that the middle latency components are also useful for the clinical diagnosis and the developmental (maturational) evaluation of sensory information processing in the sensory pathway, even though the anatomical origin is so little well known. The present study investigated the developmental changes of the MLAEP components (Pa, Nb, and Pb) to unattended acoustic stimuli in normal children as compared to adult subjects. Subjects, whose ages ranged from 3 to 24 years, included 63 normal children and 15 adult students. Click stimuli (100 dB SPL, 0.1 msec rise-fall time, 1 msec duration) were presented binaurally with the ISI 1 sec, during which the subjects watched silent color TV programs. MLAEPs were recorded monopolarly from midline placements over Fz, Cz and Pz with linked A1-A2 as the reference with bandpass filter of 5-300 Hz. In the MLAEP study, the amplitudes and latencies of Pa, Nb, Pb components were measured for 5 different age groups. The results showed that the MLAEP Pb latencies at Cz decreased progressively as a function of age, and the Pb amplitudes changed as an inverse U-shape function of age. However, there were no consistent statistical in differences in the characteristics of Pa and Nb components among the different age groups. These findings suggested that the earlier MLAEP components (Pa and Nb) and the Pb have different developmental time-tables and generator systems. The MLAEP Pb appears obviously to be a valuable tool for developmental evaluation and the investigation of the electrophysiological characteristics of brain maturation. | |||||||
