A study of the maturation of the somatosensory pathway by evoked potentials.

摘要: We investigated the somatosensory evoked potentials (SSEPs) in 62 healthy children, ten days to twelve years old. Our control group consisted of adults, sixteen thirty-six The stimulus was applied at median nerve wrist and cerebral SSEPs were recorded by electrodes placed on contralateral parietal scalp region, while for cervical SSEP recording over skin C6-C7 vertebral region. reference electrode FZ according 10-20 system. study revealed a significant change early components (NI PI) between groups different ages. latency duration NI wave form PI inversely correlated with age. These changes are most likely due gradual maturation afferent nervous system From difference latencies peak we able calculate sensory conduction time central found progressive decrease relation increase This is development postnatal myelination fibres pathway.
