A new study suggests carriers of a genetic mutation in the serotonin 2B receptor may be protected from obesity and insulin resistance.
Men with a more fragile sense of masculinity, or whose feelings of masculinity rely more on others, are more likely to act aggressively in order to prove their masculinity.
Researchers have identified 40 new genes they believe are related to aggressive behavior in both humans and mice. The findings deepen understanding of the genetic basis of aggressiveness.
Researchers have identified a novel neural circuit that detects male pheromone cues pertaining to inter-male aggression.
Researchers report that after an aggressive encounter, mice who 'won' a fight showed signs of new neuron growth in the hippocampus.
The effects of heavy drinking extend beyond those who use alcohol, a new study reports. Each year, one in five American adults are harmed as a result of someone else's drinking. People report threats of harassment, vandalism, physical aggression, financial and family problems, and harm from DUIs as main problems associated with other people's drinking. Researchers say the type of harm experienced differ by gender, with women more likely to report financial or family problems, and men reporting physical aggression and vandalism more often. Women are more likely to experience harm as a result of a family member's drinking, while men are more likely to be harmed as a result of alcohol use by a person outside the family. Even those who don't drink heavily are at three times higher risk of antisocial behaviors.
Neuroimaging reveals lower activation in the dorsolateral prefrontal cortex and angular gyrus in teenage girls with conduct disorder. Findings suggest that a reduction in prefrontal brain regions and functional connectivity during effortful emotional regulations contribute to behaviors associated with antisocial behavior in teenage girls.
Psychologists have developed a 12-point list of sexual assault prevention strategies aimed at reducing the risk of college-aged males embarking on sexually aggressive or risky sexual behaviors.
