Researchers report our brain is on high alert while listening to voices, finding we respond much faster to vocal aggression than normal or happy voices. The reason, researchers say, could be that our attention is more focused on threatening voices to help us recognize the location of a potential threat.
According to a new study, young adults who are hostile or don't deal too well with stress are at higher risk of thinking and memory problems in middle age.
A new study supports previous findings that show men have biological responses to becoming a parent. The study revealed men whose testosterone levels dropped during 9 months following birth were at higher risk of developing post partum depression. By contrast, those who experienced high testosterone were at higher risk of experiencing stress and tended to be more aggressive toward their partner.
Researchers have identified specific neurons and networks that regulate 'sundowning', a phenomenon commonly seen in Alzheimer's patients who exhibit worsening confusion and aggression levels at the end of the day.
Embedding a molecule called TRPM8 into the surface of some cells helps reduce aggression and sexual appetite in mice, a new study reports.
When aromatase+ neurons are depleted, both male and female mice are slower to show aggressive signs, a new study reports.
Social experience appears to be key for the development of separate, sex-specific neural populations and expression of aggression in male mice, a new study reveals.
Hard wired neural circuits in mice that govern aggression are strengthened following victories in aggressive encounters. Synapses in the hypothalamus show signs of LTP following aggression training.
Researchers have identified a correlation between brain stem volume and aggressive behavior in children with autism. Smaller brain stems appear to be associated with an increased likelihood of aggression.
