<prompt> Impulses which inhibit postsynaptic neuron itselfRenshaw cell inhibitionPresynaptic inhibitionDirect inhibitionIndirect inhibition  <response>: Ans. a Renshaw cell inhibitionRef: Ganong, 25th edp.122Renshaw cells are the inhibitory interneurons present in spinal cordRenshaw cells are excited by a motor neuron. In turn, Renshaw cells inhibit the same motor neuron which excites it. This stabilize the firing rate of the motor neuronsAlso called as negative feedback inhibition
