Unraveling the secrets of a good night’s sleep

Researchers have identified a signaling pathway that regulates sleep. By studying genetic mutations in mice, they were able to show that an enzyme called histone deacetylase 4 (HDAC4), which is known to suppress gene expression, plays a key role in reg…

Scientists uncover possible neural link between early life trauma and binge-eating disorder

Research has revealed how a pathway in the brain that typically provides signals to stop eating may be altered by early life trauma. The discovery, obtained from studies in mice adds new perspective to binge eating and obesity.

Study explores how ‘me-time’ affects social interaction

Cholesterol-lowering drugs linked to lower risk of bleeding stroke

People who take cholesterol-lowering drugs called statins may have a lower risk of having a type of stroke called an intracerebral hemorrhage, according to a new study. An intracerebral hemorrhage is caused by bleeding in the brain.

Socialness is in the eye of the beholder

Although people are generally predisposed to perceive interactions to be social even in unlikely contexts, they don’t always agree on exactly which information is social, according to a new study. The findings show that much of the brain responds more …

Researchers reveal how trauma changes the brain

Researchers are learning more about how traumatic events may physically change our brains. Neurologists have revealed changes to a brain mechanism used for learning and survival may play a role in how someone responds to a threat following a traumatic …

Study identifies potential link between oral bacteria and brain abscesses

Researchers have examined the records of 87 patients admitted to hospital with brain abscesses, and found that the 52 patients for whom no cause had been found were about three times as likely to have oral bacteria present in their samples.
