Research shows signalling mechanism in the brain shapes social aggression

Health Problems

Duke-NUS researchers have discovered that a growth factor protein, called brain-derived neurotrophic factor (BDNF), and its receptor, tropomyosin receptor kinase B (TrkB) affects social dominance in mice. The research has implications for understanding the neurobiology of aggression and bullying. “Humans and rodents are social animals. Our every interaction follows rules according to a social hierarchy. Failure to navigate this hierarchy […]

Study locates circadian clock that controls daily rhythms of aggression

Health Problems

Patients with Alzheimer’s disease and other forms of dementia commonly experience the sundown syndrome – a sudden worsening of confusion, agitation and aggression at the end of the day. Its daily pattern suggested that “sundowning,” as the phenomenon is also known, may be governed by the body’s internal biological clock. Synchronized by light and darkness, the circadian clock exerts control […]
