Related to Decerebration: decortication, Decerebrate posturing
severance of the brain above the medulla oblongata (along the anterior border of the quad-rigemina), used in experiments on animals in physiological research. Some time after decerebration, decerebrate rigidity of the muscles develops. Decerebration permits study of the reflex activity of the medulla oblongata and the spinal cord in the absence of influence from the interbrain and the cortex of the large hemispheres.
