1.The recent studies showed that SSR’s afferent nervous pathway was in the spinal cord and its central afferent pathway was closely correlated to the central afferent pathway of bladder sensation, which has provided us a new idea on the study of bladder sensory function.
2.For example, outside the afferent nerve fiber in week nerve passes into sensory information centre, the instruction information that efferent nerve fiber issues centre spreads effect implement, convey with the form of nerve impulse, and the biology report that nerve impulse calls behavioral potential one kind namely changes, it is the mark of nerve excitement.
3.Conclusions The results of our study suggest that the damage of sensory pathways exist in ALS. Central abnormalities of SEP were more obvious than peripheral abnormalities. SEP examination had some value in localization of sensory lesion in ALS patients.
4.Axoplasmic transport of nerve fibers; Nutrition of nerve fibers; The function of neuroglia cells; Eletrical synapse; Contact ways of central neurons; Local circuit neurons; Central facilitation; Body sensory afferent pathway, Visceral sensation; The regulation system of somatic motor, The central regulation of visceral sensation; pain sensation; The function of basal ganglia; Evoked cortical potential and electroencephalogram.
5.Conclusion The conduction path of MEP in the spinal cord is mainly the central motorius of the corticospinal bundle, while that of CSEP is the conduction bundle of the central sensation.
6.The present results indicated that the Vi, which received the afferent projections from both peripheral and central nervous system, might be involved in the information modification and play a role in primary sensory information convergence.
