Amygdala

Amygdala (Aaron Helzinger) is a supervillain appearing in American comic books published by DC Comics, who is an opponent of Batman. He has reduced mental capacity, near superhuman strength and endurance, and is prone to outbursts of violence due to medical experimentation on his brain, chiefly the removal of his amygdala. Amygdala is briefly referenced in an article by Joseph LeDoux, a neuroscientist and expert in the role of the anatomical amygdala in fear processing, as testament to popular interest in the brain area. Aaron Helzinger appeared on the second season of Gotham portrayed by Stink Fisher and the second season of the Arrowverse series Batwoman portrayed by R. J. Fetherstonhaugh. Publication history Amygdala first appeared in Batman: Shadow of the Bat #3 and was created by Alan Grant and Norm Breyfogle. Fictional character biography Anatomically, the amygdala refers to the bundle of nerve cells in the brain that control emotional associations of many kinds. Aaron Helzinger's amygdala cluster was removed in an attempt to cure him of his homicidal rage. This procedure resulted in Amygdala becoming exceedingly angry and was the opposite of what the surgery was intended to achieve. Easily led due to his childlike nature, Amygdala has been the pawn of a number of Batman villains, but when properly medicated, he can be peaceful.
