According to herrington classification the decerebrate rigidity is characterised by all except

  1. Rigidity occurs in all muscles of the body

  2. Increase in the rate of discharge of the '? efferent neuron

  3. Increased excitability of the motor neuron pool

  4. Decerebration produces no phenomenon akin to spinal shock

Explanation:

Decerebrate rigidity

  •    γ motor neuron discharge rate increased.

  •    Motor neuron pool excitability increased.

  •    Decerebration produces no phenomenon similar to spinal shock.

  •    Antigravity extensor muscles are involved in decerebrate injury.
