Sham rage Sham rage is behavior such as biting, clawing, hissing, arching the back and "violent alternating limb movements" produced in animal experiments by removing the cerebral cortex. This behavior is reversed with small lesions in hypothalamus. The term was in use by Walter Bradford Cannon and Sydney William Britton as early as 1925. Cannon and Britton were doing research on emotional expression resulting from action of subcortical areas. Cats had their neocortices removed but still displayed characteristics of extreme anger resulting from mild stimuli. ==Symptoms== The physiological symptoms of sham rage include rise in blood sugar, pulse, respiratory rates, and blood pressure. These symptoms can occur spontaneously and may also be evoked by sensory stimulations. In some cases animals have suffered several convulsive attacks followed by withdrawal of sodium barbital. It has been concluded that the cerebral cortex may play a facilitating part in this type of convulsive process. These physiological effects happen alongside the rage-like symptoms of hissing, clawing, biting, etc.
