| 1 | STOCHASTIC RESONANCE MEASURED BY THEMUTUAL INFORMATION IN THE NEURONSTHAT TRANSMIT CHAOTIC SPIKE TRAINS显示文摘The spike trains generated by a neuron model are studied by the methods of nonlinear time series analysis. The results show that the spike trains are chaotic. To investigate effect of noise on transmission of chaotic spike trains, this chaotic spike trains are used as a discrete subthreshold input signal to the integrate-and-fire neuronal model and the FitzHugh-Nagumo(FHN) neuronal model working in noisy environment. The mutual information between the input spike trains and the output spike trains is calculated, the result shows that the transformation of information encoded by the chaotic spike trains is optimized by some level of noise, and stochastic resonance(SR) measured by mutual information is a property available for neurons to transmit chaotic spike trains. | Gong Pulin Xu Jianxue Hu Sanjue(Institution of Nonlinear dynamics, School of Civil Engineering and Mechanics,Xi’an Jiaotong University, Xi’an 710049, China)(Department of Physiology, Fourth Military Medical University, Xi’an, 710032, China) | 1999 | 生物物理学报1999，15，4： | 3 |

| 5 | Lower limb pain in sympathetic-sensory coupling显示文摘Previous studies have shown that sympathetic nerves are related to certain types of pain,and this phenomenon is referred to as sympathetic-sensory coupling.Chronic pain resulting from nerve injury can be exacerbated by sympathetic stimulation or relieved by sympathetic inhibition.In the present study,the correlation between pain and sympathetic nerves was analyzed in patients with severe pain in lower limbs,as well as in a chronically compressed dorsal root ganglion(CCD)rat model(model of low back pain and sciatica).Patients with severe pain in the lower limbs underwent chemical lumbar sympathectomy(CLS),and the analgesic effects of CLS were compared with painkillers.Results demonstrated significantly relieved lower limb pain following CLS,and the analgesic effects of CLS were superior to those seen with painkillers.In the CCD rat model,dorsal root ganglion neuronal activity significantly increased as a result of electrical stimulation to the sympathetic nerves.These results suggest that sympathetic nerves are closely associated with pain,and sympathetic-sensory coupling is likely in lower limb pain in both patients and rat models of CCD. | Hongjun Yang Kairun Peng Sanjue Hu Li Xuan | 2011 | Neural Regeneration Research2011，6，2： | 0 |
