Which of the following is true regarding Renshaw inhibition?



A Collateral causes the inhibition

B Inhibition of feedback propagation

C Both

D None

Ans. C Both

Presynaptic and postsynaptic inhibition is usually produced by stimulation of certain ‘systems’ converging on a give postsynaptic neuron. For example, each spinal motor neuron regularly gives of a recurrent collateral that synapses with an inhibitory inter-neuron, which terminates on the cell body of the spinal neuron and other spinal motor neurons.

This inhibitory neuron is known as Renshaw cell after its discoverer.
