Nociceptive periods of excitation and inhibition in electromyogram in case of voluntary activation of hand muscles
The article reports a results of analysis of the characteristics of excitatory and inhibitory responses in the tonic muscles in the hands during painful electrical stimulation. It is concluded that the stimulation period, occurring after a period of silence in case of nociceptive stimulation, is an active process, mediated by descending supraspinal influences.
