Abstract:

A decrease of variation coefficient for the amplitudes of dorsal root potentials and cord dorsum potentials (CDP) was found in anaesthetized spinal cats. Reduction of the number of spikes in neurons, which are suggested to take part in generation of CDP in response to repetitive stimulation of cutaneous nerves was also seen. A maximum decrease of variation coefficient was observed at low frequency of stimulation (0.1-5 Hz). The effects observed can be due to homosynaptic depression.
