<prompt> According to Sherrington model of decerebrate rigidity is characterised by all exceptRigidity occurs all muscles of the bodyIncreased in the rate of discharge of the y efferent neuronIncreased excitability of the motor neuron poolDecerebration produces no phenomenon akin to spinal shock  <response>: A key feature of this decerebrate animal was that when the dorsal roots of spinal cord were cut differentiation the rigidity disappeared, showing that the cause of rigidity was a hyperactive stretch reflex in the antigravity muscles.
