Generalized tonic seizures mimic decorticate posturing; the majority are not associated with electrographic seizures. However, Reye's syndrome and traumatic brain injury can both cause decorticate posturing in children. There are two parts to decorticate posturing. Decerebrate and decorticate posturing are strongly associated with poor outcome in a variety of conditions. The disrupted brainstem can lead to decorticate posture, respiratory center depression and death. A brainstem damage above the red nucleus' level may cause decorticate rigidity. Decorticate animals show absence of this reflex. Decorticate rats were just as able as normal rats to accomplish the latent learning task. Decorticate posturing is also called decorticate response, decorticate rigidity, flexor posturing, or, colloquially, "mummy baby".
