Acute and chronic experiments on lower spinal (T10–T12) cats were performed to investigate the effects of epidural stimulation of the dorsal surface of the spinal cord on the initiation of locomotor activity. A zone located at the border between segments L4 and L5 was identified, stimulation of which induces locomotor activity. The parameters of epidural(More)
Using mathematical simulation of motor unit potentials (MUPs), detected by a point and rectangular plate electrode, we have shown that the muscle tissue does not act like a low-pass frequency filter on MUPs. Depending on the electrode type and its longitudinal position, the relative weight of the terminal phases (reflecting the excitation extinction) in(More)
Electrical epidural stimulation of the dorsal surface of the spinal cord at the level of the second lumbar segment induced step-like movements accompanied by the corresponding electromyographic activity in the leg muscles in patients lacking supraspinal influences as a result of vertebral trauma. Triggering of stepping movements was shown to occur with(More)
Spinal neural networks activated by epidural electrical stimulation of the spinal cord (ESSC) are known to be able to take part in generating the stepping EMG pattern and controlling locomotor behavior. We show here that noninvasive transcutaneous stimulation of the spinal cord (TES) in the lumbosacral enlargement area can initiate locomotor activity in(More)
INTRODUCTION It is impossible to imagine a modern socially-active man who does not use mobile devices and/or computers with Wi-Fi function. The effect of mobile phone radiation on male fertility is the subject of recent interest and investigations. The aim of this study was to investigate the direct in vitro influence of mobile phone radiation on sperm DNA(More)
In patients deprived of supraspinal effects, electrical epidural stimulation of the spinal cord's dorsal surface at the level of 2nd lumbar segment induces step-like movements accompanied by respective electromyographic activity of the leg's muscles. Triggering of the step-like movements occurs at certain parameters of the stimulation. The data obtained(More)
INTRODUCTION Chronic prostatitis is a widespread urological disease with a lengthy course and a propensity to frequent recurrences. Adequate response to anti-inflammatory therapy is lacking in a high percentage of patients, which causes them to seek medical advice from different doctors. Thus, the physicians are challenged to look for other reasons causing(More)
The mechanisms of stepping pattern formation during epidural spinal cord stimulation in decerebrated and chronically spinal cord transected cats have been investigated. The features of the stepping performance in hindlimb muscles depending on the parameters of epidural stimulation and afferent input were determined. It was shown that, at nonoptimal(More)
