The cycle of violence is built into mammalian brains, according to the latest issue of Behavioural Neuroscience. Scientists from Holland and Hungary have identified a fast, mutual positive feedback loop between stress hormones and a brain aggression control centre in rats.
They tested 53 rats in five experiments and found that if they stimulated the brain's aggression mechanism, they raised stress hormone levels. And if they raised hormone levels, the aggression centre went into overdrive. This would, they say, explain why aggressive behaviour escalates so easily, and why a hard day at the office could end in domestic violence.
"These stress hormones, in part by mobilising energy reserves, prepare the physiology of the body to fight or flee during stress," said Menno Kruk of the Leiden/Amsterdam Centre for Drug Research. "Now it appears these very same hormones talk back to the brain in order to facilitate fighting."
A select group of people have a unique ability to spot when someone is lying, US research shows.
A University of San Francisco study found only 31 people out of 13,000 could identify in nearly all cases when someone was lying.
The group used facial expressions, body language and ways of talking and thinking to spot liars while the others did little better than chance.
The team are now using them to help train police and other investigators.
