Super high frequency waves at nonthermal intensity may alter the membrane potential of spinal cord neurons in cats. - GreenMedInfo Summary

The influence of super high frequency (SHF) waves (lambda = 3 sm) nonthermal intensity (1.6 mWt/sm2) on work of regulator systems of a spinal cord (SC) of cats was considered. The estimation of parameters of negative components of cord dorsum potential (CDP) is made for stimulus, which apply on peripheral nerves or dorsal root earlier and after the influence of SHF on SC. Change in work of population of segmentary and non-segmentary interneurons after the SHF irradiation with 30 minutes exposition was shown. The authors consider that the main influence SHF waves is directed on a changes of membrane potential of SC neurons. The specified effect carries temporary and convertible character.
