| decerebrate | 1. To cause decerebration. 2. Denoting an animal so prepared, or a patient whose brain has suffered an injury which renders him in his neurologic behaviour comparable to a decerebrate animal. (05 Mar 2000) |
|---|---|
| decerebrate reflex | <neurology, physiology> Spontaneous extension of elbows, wrists and legs which suggests damage to the diencephalon (midbrain). Seen in cases of stroke and some cases of encephalitis. The decerebrate reflex is a clinical finding characterised by rigid contraction of the extensor and other muscles which maintain an animal in the standing position (antigravity muscles), may be seen in association with a severe stroke, intracranial haemorrhage, cerebral haemorrhage, cerebral toxin or transection of the brain below the level of the anterior corpora quadrigemina but above the vestibular nuclei, clinically may be preceded by decortication.

| decerebrate state | A peculiar neurologic condition elicited in vertebrates as a consequence of the elimination of brain function by transecting the brainstem or interrupting function by other techniques. Clinically, brain damage can result in neurological signs resembling those of a decerebrate animal. The state consists of exaggerated postures, grossly abnormal reflexes, convulsions, and extreme muscular rigidity and spasticity. (12 Dec 1998) |

| decerebrate animal |
an experimental animal that has been subjected to decerebration; such an animal exhibits rigid extension of the legs, with strong tonic contraction of the extensor muscles and to some extent the flexor muscles. See also decerebrate, and see decerebrate rigidity, under rigidity.

| decerebrate rigidity |
the posture produced in an experimental animal by decerebration (qv), marked by rigid extension of the legs. In humans it occurs as a result of lesions of the upper part of the brain stem or of severe bilateral lesions of the cerebrum and is manifested as a posture of lying in rigid extension with arms internally rotated at the shoulders and pronated; elbows, knees, and hips rigidly extended; and fingers, ankles, and toes flexed. Cf. antigravity reflex.

| decerebrate posture |
Exaggerated posture of extension as a result of a lesion to the prepontine area of the brain stem, and is rarely seen fully developed in humans. In reporting, it is preferable to describe the posture seen.
