 +=====Kluver-Bucy Syndrome=====
 +
 +Kluver-Bucy syndrome is a neuropsychological disorder that results from damage to the temporal lobes of the brain, specifically the amygdala, and hippocampus. The syndrome was first described by the American neuropsychiatrists, George Kluver and Paul Bucy, in the late 1930s, following studies of brain-damaged monkeys.
 +
 +The syndrome is characterized by a peculiar set of symptoms, including hypersexuality, hyperorality (increased oral exploration of objects), and a reduction in fear and aggression. Individuals with Kluver-Bucy syndrome may also experience changes in emotional and social behavior, including increased sociability and a decreased ability to recognize familiar objects or faces.
 +
 +Kluver-Bucy syndrome is believed to result from damage to the amygdala and hippocampus, which are important for the processing of emotional and social information, as well as for memory formation. The amygdala is responsible for processing emotions, including fear, aggression, and pleasure, and the hippocampus is responsible for forming new memories and for the consolidation of long-term memories.
 +
 +Damage to these regions can disrupt the normal functioning of the brain, leading to changes in emotional and social behavior, as well as memory deficits. For example, damage to the amygdala can result in a reduction in fear and aggression, while damage to the hippocampus can result in memory impairments.
 +
 +The exact mechanisms underlying Kluver-Bucy syndrome are not well understood, but it is thought to result from disruptions in the neural circuits that connect the amygdala and hippocampus to other regions of the brain, such as the frontal lobes and the thalamus.

 +=====Charles Whitman=====
 +
 +Charles Whitman was an American mass murderer who killed 16 people and injured 31 others in a shooting spree at the University of Texas at Austin on August 1, 1966. 
 +
 +Charles Joseph Whitman was born on June 24, 1941, in Lake Worth, Florida. He was the eldest of three brothers and was raised in a strict, disciplinarian household. As a child, he was an avid Boy Scout and showed an early aptitude for science and mechanics.
 +
 +Whitman joined the Marines at the age of 18 and served as a radar technician in Puerto Rico. After his discharge, he enrolled at the University of Texas at Austin, where he studied architecture and engineering. During this time, he also became a Scoutmaster and worked as a security guard.
 +
 +He was aged of 25 when he committed the mass shooting at the university. Just prior to the killings, Whitman had visited a psychiatrist and expressed concerns about his behavior and feelings of intense aggression and violence. Whitman's shooting spree was one of the first highly publicized mass shootings in modern American history and is often cited as a seminal event in the development of the American mass shooting phenomenon.
 +
 +An autopsy of Whitman's brain revealed that he had a glioblastoma, a type of brain tumor that had been pressing on his hypothalamus and amygdala. The hypothalamus and amygdala are important for regulating emotions and aggressive behavior, and it is believed that the tumor may have contributed to Whitman's violent behavior.
 +
 +However, it is also important to note that the relationship between brain disorders and violent behavior is complex, and that most individuals with brain tumors or other neurological conditions do not engage in violent behavior. Additionally, it is not possible to determine with certainty that the brain tumor was the sole cause of Whitman's behavior, as he had a history of depression and other psychiatric symptoms prior to the killings.
