The evoked potentials of spinal cord under influence of mechanical stimuli
Abstract
The electrical evoked potentials (EP) of spinal cord (SC) in reply to the mechanical activation were investigated. The energy of stroke variated from 1·10–3 up to 4·10–3 J. The registration of EP is realized in a L5 segment of SC, the point of stimulation was sequentially moved upwards along the SC. We have shown, that the augmentation of stimulus force produced the increase of amplitude of a potential and its duration. After excluding a place of stimulation from a place of registration the potential was decreased proportional to the square of the distance. We concluded that the mechanical percussions of the SC resulted in the development of long-term oscillating activity of neurones of SC.References
