MADISON -- The human brain is wired with natural checks and balances that control negative emotions, but breakdowns in this regulatory system appear to dramatically heighten risk of impulsive violent behavior, according to findings of a University of Wisconsin-Madison study. As part of......he popular belief that human males are genetically wired to be more promiscuous than females.
