However, when the amygdala was initially thought to be linked to fear, this gave way for research in the amygdala for emotional processes. Kheirbek [17] demonstrated research that the amygdala is involved in emotional processes, in particular the ventral hippocampus. He described the ventral hippocampus as having a role in neurogenesis and the ...
Amygdalotomy, also known as amygdalectomy, is a form of psychosurgery which involves the surgical removal or destruction of the amygdala, or parts of the amygdala.It is usually a last-resort treatment for severe aggressive behavioral disorders and similar behaviors including hyperexcitability, violent outbursts, and self-mutilation.
The amygdala is one of the best-understood brain regions with regard to differences between the sexes. The amygdala is larger in males than females, in children aged 7 to 11, [17] adult humans, [18] and adult rats. [19] There is considerable growth within the first few years of structural development in both male and female amygdalae. [20]

The skull of Phineas Gage, with the path of the iron rod that passed through it without killing him, but altering his cognition. The case helped to convince people that mental functions were localised in the brain. [208] The philosophy of the mind studies such issues as the problem of understanding consciousness and the mind–body problem.
S.M., sometimes referred to as SM-046, is an American woman with a peculiar type of brain damage that physiologically reduces her ability to feel fear.First described by scientists in 1994, [1] she has had exclusive and complete bilateral amygdala destruction since late childhood as a consequence of Urbach–Wiethe disease.
Social-emotional agnosia is mainly caused by abnormal functioning in a particular brain area called the amygdala. Typically this agnosia is only found in people with bilateral amygdala damage; that is damage to amygdala regions in both hemispheres of the brain. [citation needed] It can be accompanied by right or bilateral temporal lobe damage ...

Brain metastasis – cancer that has spread to the brain from another location in the body; Tuberous sclerosis – genetic disease that causes non-malignant tumors to grow in the brain and on other vital organs; Brain damage.
