Jan 1, 2025 · Sham rage is a physical and behavioral response in mammals that resembles anger, caused by the separation of the hypothalamus from the control of upper brain structures such as the cerebral cortex.

(A) Transection through the midbrain, disconnecting the hypothalamus and brainstem, abolishes “sham rage.” (B) The integrated emotional responses associated with “sham rage” survive removal of the cerebral hemispheres as long as the caudal hypothalamus remains intact.

The Shame-Rage Cycle is a self-perpetuating pattern where anger and destructive behaviors temporarily alleviate the feelings of shame. However, these behaviors often exacerbate shame in the long run, causing a vicious feedback loop.

Apr 1, 2006 · Two cases of "sham rage" in human beings are presented; one following insulin hypoglycemia, the other following carbon monoxide poisoning.

Jan 30, 2010 · Sham rage is defined as an affective and pathological aggressive state characterized by manifestations of fear and anger that lead to drastic physiological and behavioral changes.
