Preferred Label : decerebrate state;
MeSH definition : A condition characterized by abnormal posturing of the limbs that is associated with
injury to the brainstem. This may occur as a clinical manifestation or induced experimentally
in animals. The extensor reflexes are exaggerated leading to rigid extension of the
limbs accompanied by hyperreflexia and opisthotonus. This condition is usually caused
by lesions which occur in the region of the brainstem that lies between the red nuclei
and the vestibular nuclei. In contrast, decorticate rigidity is characterized by flexion
of the elbows and wrists with extension of the legs and feet. The causative lesion
for this condition is located above the red nuclei and usually consists of diffuse
cerebral damage. (From Adams et al., Principles of Neurology, 6th ed, p358);
